What Kind of Device Is a Dual-10G Mutual-Backup Optical Multiplexer?

A dual-10G mutual-backup optical multiplexer is a device that packs services of multiple different interface types into the same optical fiber channel for transmission. One unit is placed at each end: one end multiplexes E1, Ethernet and telephone voice signals onto a 10Gbps optical path, and the other end demultiplexes and restores them, delivering each service to the existing switch, protection device or voice channel equipment in its original interface standard. As a typical product showcase, this type of optical multiplexer is widely used in government private network optical fiber communication solutions, military emergency communications vehicle solutions and smart mining communication solutions.

The optical ports of the IDM OMP4000-10G use pluggable SFP modules, with an optical fiber rate of 10Gbps, single-mode fiber (multi-mode optional), wavelengths of 1310nm/1550nm, a transmit optical power of -1~-3dBm, and a receiver sensitivity better than -24dBm. On this basis, the link loss budget can be calculated and SFP optical modules of the corresponding distance grade can be selected. The equipment provides 2 10Gbps SFP optical ports, which can be configured for dual-fiber mutual backup, with the two optical paths backing up each other. This multi-service optical multiplexer is developed and manufactured by Raytrans and is a high-bandwidth multiplexing model in its telephone optical multiplexer product line.

The three services each occupy an independent channel inside the IDM OMP4000-10G and do not change each other's encoding or frame structure. E1 services are carried by transparent transmission at a bit rate of 2048Kbps and line coding of HDB3, without changing the time slot content; Ethernet services use adaptive negotiation at 10M/100M/1000M and comply with IEEE802.3; telephone voice runs over PCM voice channels, with an audio range of 300Hz~3400Hz, ITU G.711 A-law compression, and a loop current of 25mA per channel. The three services share the 10Gbps optical path bandwidth and arrive at the opposite-end site simultaneously. As a professional optical multiplexer manufacturer, Raytrans integrates complete telephone optical multiplexer and multi-service optical multiplexer functions into this series of optical multiplexers.

How do the dual 10G SFP optical ports implement dual-fiber mutual backup?

The key to dual-fiber mutual backup is to connect two devices with two independent optical fibers, so that services are not interrupted when either fiber or optical module fails. IDM OMP4000-10G provides 2 x 10Gbps SFP optical interfaces. The two fibers can run along different duct routes or different optical cable sections. The optical ports work in 1+1 protection mode, and services are switched to the standby optical path after the primary optical path fails, so the single point of failure risk of the trunk link is reduced accordingly. Optical modules are selected according to link length, and pluggable replacement does not require touching other boards in the chassis. This feature makes the optical multiplexer stand out in scenarios with extremely high requirements on link reliability, such as military emergency communications vehicle solutions.

How is the dual power supply connected?

The key point of dual power supply access is to feed two independent power sources to the two power inputs of the device, so that service remains uninterrupted when either feed fails. The IDM OMP4000-10G supports three power supply modes: DC-48V, AC220V and dual power supply. The -48V direct current and 220V AC mains power commonly used in communications equipment rooms can each occupy one feed. The overall power consumption is ≤100W, with low requirements on storage battery capacity and equipment room air conditioning. During wiring, first check whether the equipment room power format matches the device labeling, then check whether the grounding and terminal crimping are secure, and then power on to observe the power and alarm indicator LEDs. After confirming normal received optical power, verify services one by one. As an optical multiplexer manufacturer, Raytrans provides well-developed dual power supply redundancy design for demanding applications such as smart mining communication solutions.

Differentiated Value: Dual 10G Mutual Backup, 4-Channel Gigabit Isolation and E1 Transparent Transmission

As a product showcase model for private networks, the IDM OMP4000-10G concentrates its differentiation in four points: dual 10G mutual backup on the trunk optical path, physical isolation of Ethernet ports, E1 transparent transmission in compliance with standards for interfacing with existing private networks, and SNMP network management for remote maintenance. The capabilities of this optical multiplexer and their actual value to private network customers are listed in the table below:

Typical Application Scenarios

As a multi-service optical multiplexer, the IDM OMP4000-10G is deployed mainly in point-to-point mode: one device at each end, interconnected by optical fiber. The E1, Ethernet and telephone services at the site side are restored at the central equipment room and then connected to existing transmission and switching equipment; when a site is expanded, only service boards need to be added, without laying new optical cables.

Electric Power and Energy Industrial Private Network

Between electric power substations, switching stations and new energy stations, dispatch telephones, automation E1 dedicated lines and in-station data need to be transmitted simultaneously. The IDM OMP4000-10G is installed at each station, using one 10Gbps single-mode fiber to multiplex the inter-station dispatch audio, E1 channels and data services for transmission, replacing the previous practice of stacked devices and multiple line rentals. The 4 groups of E1 channels are transparently transmitted in accordance with ITU-T G.703 and can be directly connected to relay protection devices and dispatching switching equipment, with no configuration adjustment required at the opposite end; the telephone voice interface is encoded in accordance with ITU G.711 A-law, with a loop current of 25mA per channel, and can be directly connected to dispatch telephone equipment.

Rail Transit and Pipe Gallery Communications

Metro stations, depots and urban underground pipe galleries have distributed sites with long spacing, and dedicated telephones, monitoring data and device network management information usually need to be transmitted simultaneously between stations. The dual 10G optical ports of the IDM OMP4000-10G can run through different ducts respectively to form dual-fiber mutual backup, preventing a total interruption of inter-station services caused by a single optical cable being dug up; the 4 physically isolated Ethernet ports can carry train-operation-related networks and O&M office networks separately without affecting each other. The 1U enclosure of the device is deployed in station communications equipment rooms and pipe gallery node cabinets, facilitating centralized maintenance.

Military and Government Private Networks

Military and government private networks impose high requirements on link survivability and self-maintenance, and sites are often distributed in the field and remote areas. The IDM OMP4000-10G uses one 10Gbps optical fiber to aggregate voice, data and dedicated line services, reducing the amount of optical cable laying and the exposure surface; DC-48V and AC220V dual power supply access adapts to mixed power supply scenarios of field generators, storage batteries and mains power, and the SNMP network management interface allows the superior equipment room to remotely monitor the operating status of each site, reducing personnel travel. This optical multiplexer is also suitable for government private network optical fiber communication solutions and military emergency communications vehicle solutions, and can also leverage its optical fiber multiplexing advantages in smart mining communication solutions.

How to Select an Optical Multiplexing Equipment

How to select optical multiplexing equipment can be closed out by checking three items one by one: number of service channels, optical fiber line conditions, and power supply and environmental conditions.

• Check service types and number of channels: confirm how many groups of E1 channels, how many channels of telephone voice and how many channels of Ethernet are required, and compare them one by one with the 4 groups of E1, 4 physically isolated gigabit ports and 30 telephone interfaces (telephone module required) of the IDM OMP4000-10G; if the number of channels does not match, confirm other configuration models in the same series with the optical multiplexer manufacturer.

• Check optical fiber line conditions: confirm single-mode or multi-mode, whether the wavelength is 1310nm or 1550nm, and the link loss budget; after calculating with the transmit optical power of -1~-3dBm and the receiver sensitivity better than -24dBm, determine the distance grade of the SFP optical module; the trunk link is recommended to be planned with dual optical port mutual backup.

• Check power supply and environment: DC-48V, AC220V or dual power supply must match the site power supply; the ambient temperature is 0℃～40℃ and the humidity does not exceed 90% (non-condensing); deployment in a standard equipment room or in a temperature-controlled cabinet is recommended.

• After power-on, first confirm normal received optical power at the optical port indicator LEDs, then verify E1, Ethernet and telephone services one by one, which can shorten the commissioning time.

Conclusion

As a dual 10G mutual backup optical multiplexing equipment, the IDM OMP4000-10G uses one optical fiber to simultaneously carry E1, gigabit Ethernet and telephone voice services: 2 10Gbps SFP optical ports can provide dual-fiber mutual backup, keeping the private network trunk link free of fiber breaks; 4 physically isolated gigabit ports securely separate production and management services; 4 groups of E1 transparent transmission are compatible with G.703 for seamless interfacing with power relay protection; the standard SNMP network management interface, together with DC-48V/AC220V dual power supply and ≤100W overall power consumption, adapts to unattended sites of electric power, rail transit and military and government private networks.
