What is a multi-service over a single fiber optical multiplexer?

A multi-service over a single fiber optical multiplexer is an optical multiplexer that packs four types of services—video, telephone, data, and Ethernet—into the same pair of optical fiber transmission channels. It replaces the previous practice of separately deploying video optical multiplexers, telephone optical multiplexers, and data multiplexing equipment, converging the transmission tasks previously accomplished by stacked devices into one device and one optical fiber.

IDM-Video Phone multi-service video optical multiplexer is designed exactly along these lines: the device carries bidirectional single-channel video signals, 2 telephone channels, and 2 data channels over the optical link, with optional 2 Ethernet channels and 2 high-fidelity audio inputs. The site side no longer needs separate transmission devices for video, telephone, and data, simplifying cabling and equipment box space in industrial private networks.

The difference between a multi-service over a single fiber optical multiplexer and an ordinary optical multiplexer that only transmits video lies in the variety of services and the number of interfaces. IDM-Video Phone multi-service video optical multiplexer provides bidirectional single-channel video signals, 2 telephone channels, and 2 data channels. The telephone section provides FXO and FXS interfaces, while the data section provides three types: RS-232, RS-422 (4-wire), and RS-485 (2-wire).

IDM-Video Phone multi-service video optical multiplexer also offers optional 2 Ethernet channels and 2 high-fidelity audio inputs, so video, calls, data acquisition, and network backhaul can be completed simultaneously over one optical fiber link. The interface types and quantities are determined by the on-site service list.

The way a multi-service over a single fiber optical multiplexer maintains high-quality images is through all-digital uncompressed video transmission. The video signal of IDM-Video Phone multi-service video optical multiplexer is sent into the optical channel without compression encoding, avoiding the loss of detail and encoding and decoding delay caused by compression.

IDM-Video Phone multi-service video optical multiplexer has a video sampling bit width of 8bit, a video bandwidth of 0Hz to 6.5MHz, and a video SNR ≥70dB (weighted), compatible with NTSC, PAL, and SECAM formats. Its transparent data encoding makes it compatible with the products of major camera manufacturers.

How to Select a Multi-Service over a Single Fiber Optical Multiplexer?

To select a multi-service over a single fiber optical multiplexer, first check the number and direction of services to be connected against the on-site service list, then determine the optical module configuration and model grade according to transmission distance and environmental conditions, and finally check the power supply mode and installation space. The selection of the Raytrans IDM-Video Phone multi-service video optical multiplexer can proceed along the following three dimensions, helping users quickly lock in the right optical multiplexer model.

Determine the Base Model by Number and Direction of Video Channels

The number and direction of video services determine the base configuration of the device. When images need to be transmitted in both directions between two points, choose the bidirectional single-channel video configuration; when only one image needs to be sent back in one direction, the unidirectional video configuration is sufficient; when the remote image must be sent back on site while the opposite end simultaneously sends back one image, choose the bidirectional video configuration.

The video interface of the IDM-Video Phone multi-service video optical multiplexer is BNC, 75Ω unbalanced, consistent with the video interface forms of common cameras, optical multiplexer transmit/receive ends and display devices; connect according to the input/output direction. As a professional optical multiplexer manufacturer, Raytrans provides complete interface descriptions and wiring diagrams in its product showcase, making it easy for engineering personnel to select models by comparison.

Equip Services by Telephone, Data and Ethernet Interfaces

The number of service interfaces must align with the actual needs of on-site telephones, control devices and the network. The IDM-Video Phone multi-service video optical multiplexer comes standard with 2 telephone and 2 data; telephones connect to an SPC exchange or telephone via FXO and FXS interfaces. For scenarios requiring multiple telephone access, the Raytrans telephone optical multiplexer series can also be selected for flexible expansion.

The data port of the IDM-Video Phone multi-service video optical multiplexer supports three types of interfaces: RS-232, RS-422 (4-wire) and RS-485 (2-wire), and can connect to PTZ control, access control and data acquisition terminals; when the network also needs to be sent back on site, add 2 Ethernet (10M/100M adaptive) and 2 high-fidelity audio connections per the optional configuration list, and a single optical fiber can simultaneously enable video, telephone, data and network services. This multi-service optical multiplexer design is particularly suited to the multi-service convergence transmission needs of government private network optical fiber communication solutions.

Determine the Optical Module and Model Grade by Transmission Distance and On-Site Environment

Transmission distance and environmental conditions determine the choice of optical module and unit grade. The IDM-Video Phone multi-service video optical multiplexer comes standard with 20Km single-mode transmission; for longer distances, long-distance optical modules can be optionally installed to achieve longer-distance optical fiber transmission, and when the link needs to be extended in the middle, a video lossless regenerative repeater can be used.

For outdoor equipment boxes, outdoor mounting poles or plants with large temperature fluctuations, an industrial-grade wide-temperature configuration (-40℃ to +85℃) is recommended, and confirm whether the power supply mode is AC220V or DC-48V. Before installation, also check whether the 110mm×168mm×28mm unit dimensions match the on-site installation position; the compact structure makes it easy to fit into narrow equipment boxes or cabinets. As an experienced optical multiplexer manufacturer, Raytrans provides detailed model specification comparisons on its product showcase pages, helping users quickly determine the configuration grade according to the actual environment.

How to Calculate a Single-Fiber 20Km Repeaterless Link, and How to Extend It When the Distance Is Insufficient?

The transmission distance of a multi-service over a single fiber optical multiplexer depends on the margin among the optical module's transmit optical power, receiver sensitivity and line loss. The IDM-Video Phone multi-service video optical multiplexer comes standard with single-fiber 20Km transmission, corresponding to a 155M optical interface, transmit optical power of -15 to -8dBm, and receiver sensitivity better than -32dBm.

The available optical power margin left between the two ends of the IDM-Video Phone multi-service video optical multiplexer is the margin portion of the link budget; the actual achievable distance must also be calculated in combination with factors such as optical cable loss, the number of fiber adapters and splice points, and termination quality.

A single-fiber 20Km link can extend its coverage in three ways: first, install long-distance optical modules to achieve longer-distance optical fiber transmission; second, use a video lossless regenerative repeater to segment the long link and amplify it through regeneration, so that video quality does not degrade due to regeneration; third, first measure the received optical power on site, then decide based on the measured value whether to add a repeater or replace the optical module.

In engineering practice, it is recommended to leave a certain optical power margin at both ends of the link to avoid insufficient link margin after optical cable aging or connector contamination. Transmission distance calculation should be considered together with service direction; the IDM-Video Phone multi-service video optical multiplexer simultaneously carries video, telephone, data and Ethernet services over a single optical fiber, and a link interruption affects all services, so the design phase should incorporate the optical cable route, the number of patch points and spare fiber cores into the solution. In government private network optical fiber communication solutions and military emergency communications vehicle solutions, accurate calculation of the link budget is particularly critical, and Raytrans can provide targeted technical support.

For lines with high reliability requirements, spare fiber cores and backup devices can be reserved in the solution to facilitate fast switchover when a failure occurs.

How Much Power Does a Multi-Service over a Single Fiber Optical Multiplexer Consume, and How to Choose Power Supply and Environmental Conditions?

The overall power consumption of a multi-service over a single fiber optical multiplexer is ≤6W, with power supply modes of AC220V/DC-48V. Operating temperature range, power supply mode and line protection together determine whether the device can operate online over the long term at unattended sites.

The industrial-grade configuration of the IDM-Video Phone multi-service video optical multiplexer covers an operating temperature of -40℃ to +85℃, with a standard operating temperature of -15℃ to +65℃, a storage temperature of -25℃ to +75℃, and a relative humidity of 0 to 95% (non-condensing). The device can be used in outdoor equipment boxes, plant mounting poles and equipment rooms with large temperature fluctuations.

Power supply modes support AC220V and DC-48V; communications equipment rooms and private network cabinets can directly draw DC -48V power, and an overall power consumption of ≤6W puts less pressure on cabinet power supply and heat dissipation. The IDM-Video Phone multi-service video optical multiplexer adopts a self-recovering fuse circuit design with lightning protection; after protection is triggered by a lightning strike or line abnormality, the circuit can recover automatically, reducing downtime caused by manual replacement of fuse components.

Wide-temperature and line protection conditions need to be determined at the design stage together with the optical cable laying method. Aerial optical cables or those laid along poles are more likely to be affected by induced lightning current; for such routes, equipotential grounding treatment is recommended inside the equipment boxes at both ends, and industrial-grade models should be selected according to the on-site environment. Point-to-point links inside equipment rooms usually meet requirements with a standard temperature grade, and the construction quality of power and ground lines also affects long-term operation performance of the device. Raytrans, as an optical multiplexer manufacturer, clearly marks the power consumption and environmental parameters of each model in its product showcase, making it easy for users to select models as needed.

How to Wire and Deploy a Multi-Service over a Single Fiber Optical Multiplexer?

The wiring of a multi-service over a single fiber optical multiplexer can be matched item by item according to service type: video over BNC coaxial, telephone over telephone cable, data over data cable, Ethernet over network cable, and the optical path over optical fiber patch cords, with both ends configured as a pair. The on-site wiring correspondences of the IDM-Video Phone multi-service video optical multiplexer are shown in the table below.

Service	Equipment-Side Interface	On-Site Connection	Description
Video	BNC, 75Ω unbalanced	Camera, optical multiplexer, display device	Connect according to the on-site signal flow direction for input/output
Telephone	FXO, FXS	SPC exchange, telephone	Audio range 300Hz to 3400Hz, A-law companding in ITU G.711
Data	RJ-45	PTZ controller, access control and data acquisition terminal	Wire according to RS-232, RS-422 (4-wire), RS-485 (2-wire)

Figure 2: Close-up of the video, telephone and data interface layout on the rear panel of the IDM-Video Phone optical multiplexer

The deployment of the IDM-Video Phone multi-service video optical multiplexer is mainly point-to-point direct connection. Deploy one device at each end, connect them directly with a single optical fiber, connect a camera, telephone, control device and network at one end, and connect a display device, switch and telephone network at the other end, to complete end-to-end transmission of video, telephone, data and Ethernet.

Point-to-point direct connection offers clear networking and few points of failure, and is suitable for occasions where the distance between a monitoring point and a duty room is relatively long and multiple types of services need to be sent back together. During deployment, first complete the device power-on self-test and confirmation of the received optical power on the optical path, then enable video, telephone, data and network services item by item; when on-site capacity expansion is needed, simply add Ethernet and high-fidelity audio interfaces per the optional configuration list. In military emergency communications vehicle solutions, such a rapidly deployable multi-service optical multiplexer with complete interfaces is particularly important, and Raytrans can provide complete product showcases and solution support for video optical multiplexers and multi-service optical multiplexers.

Typical Application Scenarios

Video Surveillance Private Network Along Electric Power and Rail Transit Lines

The monitoring points of electric power and rail transit are distributed across substations, traction substations, pump stations and along the lines, with large spacing between stations and most being unattended; cabinets usually have no air conditioning or permanent staff. The IDM-Video Phone multi-service video optical multiplexer uses a single optical fiber to send back bidirectional single-channel video, 2 telephone, 2 data and optional 2 Ethernet to the dispatch end together; as a multi-service convergence product in the optical multiplexer family, a single device can achieve the composite access capability that previously required multiple product showcases.

On-site images, dispatching calls, device status data and network services share a single fiber core, eliminating the need to lay separate lines for each type of signal, and reducing duct occupation and excavation along the route accordingly. The device's industrial-grade operating temperature covers -40℃ to +85℃ and relative humidity 0 to 95% (non-condensing), and it can be deployed as an industrial-grade wide-temperature model in field cabinets and outdoor equipment boxes, adapting to environments with large temperature differences between winter and summer along the route.

Safe City and Expressway Unattended Sites

The monitoring points of Safe City and expressways are distributed in a belt along the route, and the distance from intersection equipment boxes to the surveillance center often exceeds the usable range of coaxial cable and twisted pair. The single-fiber 20Km repeaterless capability of the IDM-Video Phone multi-service video optical multiplexer can cover the typical distance between adjacent toll stations, tunnel portals and the surveillance center, with front-end camera images traveling along a single fiber core directly to the center without the need for repeaters and routing/switching equipment along the way.

Video, telephone, and data services are multiplexed over a single optical cable, reducing road excavation and duct occupation; broadcast intercom and emergency telephone between the tunnel and the toll station can be connected to the telephone optical multiplexer channel, while the data channel is used for backhaul of PTZ and device status at the opposite end. Cabinets along the line are mostly installed outdoors, and the industrial-grade wide-temperature and self-recovering lightning protection fuse circuit design adapt to long-term online operation under wind, frost, and thunderstorm conditions; when the link is longer, long-distance optical modules can be added or video lossless regenerative repeaters used to extend it in segments.

Field Mobile Command Communications for Military and Public Security

Field mobile command scenarios for military and public security involve temporary setup and quick deployment, and the site often has no fixed equipment room or mains power. The IDM-Video Phone multi-service optical multiplexer adopts a compact 110mm×168mm×28mm structure, making it easy to carry in a vehicle and deploy quickly. A single optical fiber can backhaul on-site video, command calls, data, and network services to the command vehicle or temporary command post, meeting the practical requirements of military emergency communications vehicle solutions for rapid deployment and multi-service convergence.

For power supply, AC220V/DC-48V dual power supply is optional, and the overall power consumption is ≤6W, making it easy to get power according to on-site power conditions and to deploy under vehicle-mounted direct current power or temporary generator conditions.

The IDM-Video Phone multi-service optical multiplexer is compatible with NTSC, PAL, and SECAM formats and can interface with camera equipment of different formats on site; its transparent data encoding makes it compatible with the products of major camera manufacturers, facilitating coordinated operation with existing communications equipment.

Summary

The IDM-Video Phone multi-service optical multiplexer is a multi-service-over-one-fiber optical multiplexer that aggregates video, telephone, data, and Ethernet services onto a single optical fiber. All-digital uncompressed video transmission brings picture quality up to broadcast-grade standards, and single-fiber 20Km transmission with video lossless regenerative repeaters supports long-distance coverage.

Industrial-grade wide temperature, self-recovering lightning protection circuits, and AC220V/DC-48V dual power supply address harsh on-site conditions such as video surveillance private networks along electric power and rail transit lines, unattended sites in Safe City and expressway projects, and field mobile command communications for military and public security. When interface configuration, power supply mode, and transmission distance need to be checked per project, they can be confirmed item by item based on the actual service list and the manufacturer's technical documentation.
