What Kind of Device Is the Broadband Fiber Optic Multiplexing Module, and What Services Can It Access?
The broadband fiber optic multiplexing module concentrates the common service interfaces on an 86mm×71mm board with robust connectors, so that after connection only a pair of optical fibers is needed to complete service backhaul between the remote station and the center. The standard version provides the following interfaces by default:
- Ethernet: 2 Ethernet interfaces sharing 100M bandwidth, used to carry IP data and video.
- Telephone: 2 automatic telephone interfaces, optionally configurable as FXS for connecting telephones, FXO for connecting exchanges, MAG for connecting magneto telephones, or for 2-wire audio access.
- Data: 2 RS422 interfaces, used to carry low-speed synchronous or asynchronous data.
- High-fidelity audio (optional): an optional 1-channel HiFi high-fidelity stereo audio channel is available.
What Services Can the Dual Expansion Interfaces Extend?
The two expansion interfaces are where services are tailored per project; the same broadband fiber optic multiplexing module can be configured with different service combinations for different projects. The available expansion directions include:
- Bidirectional analog video input and output interfaces, used for video image backhaul.
- Up to 4 E1 interfaces, used to carry E1 circuit services, compliant with ITU-T G.703.
- 8 I/O input and output components, used to collect on/off signals and output control signals.
Other expansion directions can be proposed per project and customized by the manufacturer as required.

How Is a Business-Card-Size Embedded Board Installed into User Equipment?
The broadband fiber optic multiplexing module is delivered in board-level form, so that integrators can add a fiber multiplexing channel directly into their own equipment instead of adding a separate unit. The key points for installation and power supply access are as follows:
- Board dimensions: the PCB measures 86mm×71mm, comparable to the size of a business card (90mm×54mm), so it can be easily installed into the user's equipment.
- Power supply: the circuit board is powered by +5V; the power supply access is determined by the power structure of the user's equipment.
- Interface mounting: the user interfaces use robust connectors, for reliable connection in vibration environments.
- Fiber configuration: the fiber can be configured as single-fiber or dual-fiber, selected according to the project's optical fiber resources and link protection requirements.
- Industrial-grade customization: the module can be customized to industrial-grade standards; requirements such as temperature range and protection can be discussed with the manufacturer.

Typical Application Scenarios
The applications of the broadband fiber optic multiplexing module center on two types of sites: one is where the equipment itself lacks a fiber multiplexing board and a 250M multiplexing channel needs to be embedded into an existing unit; the other is where a remote station carries many types of site services and laying multiple cables separately is costly. The following describes the wiring and deployment approach by industry.
Airborne and Marine Equipment Integration
Airborne and shipborne equipment have high requirements for board size, power supply and connection reliability. The broadband fiber optic multiplexing module has a PCB measuring 86mm×71mm, comparable to the size of a business card, uses +5V power supply and robust connectors for the user interfaces, and can be embedded directly into the enclosure of airborne or shipborne communications equipment. One board is enough to bring the onboard telephone, Ethernet and RS422 data into a pair of optical fibers, reducing the number of harnesses in the cabin; when video backhaul is required, the two expansion interfaces can be configured as bidirectional analog video input and output interfaces.
Unattended Communication Relay
Unattended relay stations usually require no on-site maintenance, and the station carries only telephones, serial port data and a small amount of IP services. The broadband fiber optic multiplexing module concentrates 2 telephone interfaces, 2 RS422 interfaces and 2 shared 100M Ethernet interfaces on one board, so that with a pair of optical fibers the service backhaul between the relay station and the center is completed, and the station does not need a separate unit for each type of service. The fiber can be configured as single-fiber or dual-fiber: the single-fiber option saves optical fiber resources, while the dual-fiber option is convenient for building a redundant link.
Security Surveillance
Security surveillance sites are scattered, and the site often needs to backhaul video, intercom audio and control signals at the same time. The expansion interfaces of the broadband fiber optic multiplexing module can be configured as bidirectional analog video input and output interfaces, used for image backhaul; the 2 telephone interfaces can connect intercom or dispatch telephones; the 2 RS422 interfaces are used for serial port data such as PTZ control; and the 2 shared 100M Ethernet interfaces carry IP camera data. The services are concentrated on an 86mm×71mm board, making it easy to install into the equipment box at the front end.
OEM Manufacturing of Industrial Private Network Equipment
When industrial private network equipment manufacturers need to add fiber multiplexing capability to their own products, they can embed the broadband fiber optic multiplexing module directly into the unit. The module supports industrial-grade customization, the user interfaces use robust connectors, and the interfaces and extended services can be tailored per project; 2 shared 100M Ethernet interfaces, 2 telephone interfaces and 2 RS422 interfaces cover the common service combinations of private network equipment. Equipment manufacturers complete power supply access and mounting according to the structure of their own products, thus filling in the fiber multiplexing channel with a relatively low amount of change.
Conclusion
The broadband fiber optic multiplexing module carries 250M fiber multiplexing bandwidth on a business-card-size board, bringing 2 shared 100M Ethernet interfaces, 2 telephone interfaces and 2 RS422 interfaces into a pair of optical fibers, and leaving two expansion interfaces that can be customized as required, configurable with 4 E1 interfaces, 8 I/O or bidirectional analog video. For projects that need to embed fiber optic multiplexing capability into their own equipment, such as airborne and shipborne equipment integration, unattended communication relay, security surveillance and OEM manufacturing of industrial private network equipment, the IDM_OPTIMUX_SKY broadband fiber optic multiplexing module provides a board-level integration approach with +5V power supply and customizable interfaces.
