What kind of device is 10G optical multiplexing equipment
10G optical multiplexing equipment belongs to the high-rate models in the optical multiplexer product line. It packs services of multiple different interfaces into a single optical fiber transmission channel, with one unit placed at each end: one end multiplexes E1, Ethernet and telephone voice signals onto the 10Gbps optical path, and the other end demultiplexes and restores them, delivering the services as-is to the existing switches, SPC switching equipment or protection devices according to interface standards. As an important category of optical multiplexing equipment, 10G optical multiplexing equipment mainly targets private network scenarios with high requirements for bandwidth and service isolation.
The optical port of IDM OMP4000-10G uses a pluggable SFP module, with an optical fiber rate of 10Gbps, single-mode fiber (multi-mode optional), wavelengths of 1310nm/1550nm, transmit optical power of -1~-3dBm, and receiver sensitivity better than -24dBm. SFP optical modules of the corresponding distance grade can be selected according to the line loss budget.
The three types of services each occupy an independent channel inside IDM OMP4000-10G, without changing each other's encoding or frame structure. E1 services are carried by transparent transmission at a bit rate of 2048Kbps and HDB3 line coding, without changing the time slot content; Ethernet services are auto-negotiated at 10M/100M/1000M adaptive, compliant with IEEE802.3.
Telephone voice runs over PCM voice channels, with an audio range of 300Hz~3400Hz, compressed in accordance with ITU G.711 A-law, and a loop current of 25mA per channel. The three types of services share the 10Gbps optical path bandwidth and arrive at the opposite-end site simultaneously. This multi-service optical multiplexer design approach enables a single device to perform the work previously done by multiple single-function optical multiplexers.

How to Connect the Dual Power Supply of an Optical Multiplexing Equipment
The key point of dual power supply access is to feed two independent power feeds to the two power inputs of the equipment respectively, so that services are not interrupted when either feed fails. 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, and the overall power consumption is ≤100W.
During wiring, first check whether the power supply format of the equipment room is consistent with the equipment labeling, then check whether the grounding and terminal crimping are secure, and then power on to observe the power supply and alarm indicator LEDs. After confirming normal received optical power, verify the services one by one. In the product showcase of its telephone optical multiplexers and multi-service optical multiplexers, Raytrans provides detailed power supply wiring instructions and technical support, making it easy for engineering personnel to quickly complete commissioning.
Typical Application Scenarios
The deployment mode of IDM OMP4000-10G is mainly point-to-point: one unit is placed at each end and interconnected by a single optical fiber. The E1, Ethernet and telephone services at the site side are restored in 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 optical cables again. As a 10G optical multiplexing equipment for the private network market, the core advantage of its product showcase lies precisely in this multi-service over a single fiber carrying capacity.

Electric Power and Energy Private Network: Dual 10G Optical Port Mutual Backup, Uninterrupted Service over a Single Fiber
Between electric power substations, dispatch stations and energy station sites, it is usually necessary to simultaneously transmit dispatch telephone, automation E1 dedicated lines and in-station Ethernet data. IDM OMP4000-10G is deployed at each site, using a single 10Gbps single-mode fiber to multiplex inter-station dispatch audio, E1 channels and data services for transmission, replacing the previous practice of stacking multiple devices and renting multiple lines. This multi-service optical multiplexer integrates telephone, E1 and Ethernet services onto the same platform, reducing the number of stacked devices in the equipment room.
The telephone voice interface of the device complies with ITU G.711 A-law, with a loop current of 25mA per channel, and can be directly connected to dispatch voice equipment; the E1 interface provides transparent transmission at 2048Kbps, HDB3, PCM30/31, and the dispatch switch and relay protection device at the opposite end require no configuration changes. With the dual 10G SFP optical port mutual backup configuration, when one optical port link fails, services switch over to the other, and critical circuits on the backbone link are not interrupted.
Rail Transit Private Network: 4 Groups of E1 and 4 Physically Isolated Gigabit Ports, Multi-Service Integrated Multiplexing
Between rail transit stations, depots and line sections, it is necessary to transmit train telephone, signaling E1 channels, monitoring and office data. IDM OMP4000-10G provides 4 groups of E1 interfaces and 4 physically isolated 10/100/1000M Ethernet interfaces. Physical isolation means that each Ethernet service does not affect the others, and a broadcast storm or abnormal traffic on one channel will not affect the remaining channels.
The Ethernet interfaces comply with IEEE802.3, with adaptive rates of 10M/100M/1000M, and can be directly connected to in-station switches; the E1 interfaces provide transparent transmission for existing channels of the signaling system and the dedicated communications network, and the station side can complete service access without replacing existing equipment.
Military and Government Private Network: Dual Power Supply and 10G Backbone, Reliable Bearer for Unattended Sites
Remote stations of military, government and public safety systems are often unattended, with limited power supply and on-site maintenance conditions. IDM OMP4000-10G supports DC-48V and AC220V dual power supply access. When a single power supply fails, the other continues to supply power. The overall power consumption is ≤100W, and it can be deployed in a temperature-controlled cabinet in a 1U enclosure. In military emergency communications vehicle solutions, the device can quickly establish temporary communication links; in government private network optical fiber communication solutions, it can serve as optical multiplexing equipment at backbone nodes for long-term stable operation.
The device has an operating temperature of 0℃～40℃ and humidity ≤90% (non-condensing), provides function control switches and alarm indications, and can provide an SNMP network management interface as required, making it easy to remotely monitor the operating status of remote stations from the central equipment room and reduce the frequency of on-site inspection.
Differentiated Value: Dual 10G Optical Ports, E1 Transparent Transmission, Dual Power Supply and 30 Telephone Channels
The differentiation of IDM OMP4000-10G is concentrated in five points: dual 10G SFP optical port mutual backup, 4 groups of E1 transparent transmission, dual power supply, 30-channel telephone access and adaptive gigabit Ethernet. The correspondence between these five capabilities and the actual value for private network customers is shown in the following table:
Differentiation Point | Specific Capability | Value for Private Network Customers |
|---|---|---|
Dual 10G optical ports: dual 10G SFP optical port mutual backup | Provides 2 10Gbps SFP optical interfaces, with single-fiber or dual-fiber options, and provides 1+1 optical port protection in the dual optical port configuration | When one optical port link fails, services switch over to the other, critical circuits on the backbone link are not interrupted, ensuring the reliability of the private network backbone |
E1 transparent transmission: 4 groups of E1 transparent transmission | Provides 4 groups of E1 interfaces, bit rate 2048Kbps, line coding HDB3, supports ITU-T G.703, frame structure PCM30/31, using transparent transmission mode | Compatible with existing electric power PCM30/31 services, and the relay protection and dispatch switch at the opposite end require no configuration changes |
Dual power supply: dual power supply | Supports DC-48V and AC220V dual-channel access, overall power consumption ≤100W | A single power supply failure does not affect service operation, suitable for unattended equipment rooms and -48V communication power supply environments |
30 telephone channels: 30 telephone interfaces | After installing the telephone module, provides 30 telephone interfaces, audio 300Hz~3400Hz, ITU G.711 A-law, loop current 25mA per channel | One device carries 30 channels of dispatch voice, eliminating the workload of separately deploying voice optical multiplexers and wiring |
How to Select 10G Optical Multiplexing Equipment: Three Items to Verify
How to select 10G optical multiplexing equipment can be closed out by verifying three items one by one: number of service channels, optical fiber line conditions, and power supply and environmental conditions.
Service type and number of channels: confirm how many groups of E1 channels, how many channels of telephone voice and how many Ethernet channels are required, and compare them item by item with the actual configuration of IDM OMP4000-10G. If the number of channels does not match, confirm other configuration models in the same series with the optical multiplexer manufacturer.
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 receiver sensitivity better than -24dBm, determine the distance grade of the SFP optical module.
Power supply and environment: DC-48V, AC220V or dual power supply must match the site power supply. The ambient temperature is 0℃～40℃ and humidity does not exceed 90% (non-condensing). Deployment in a standard equipment room or a temperature-controlled cabinet is recommended.
After the device is powered on, first confirm that the optical port indicator LED shows normal received optical power, then verify E1, Ethernet and telephone services one by one, which can shorten commissioning time.
