What Does E1 Transparent Transmission Mean for an Optical Multiplexer?

E1 transparent transmission means that the optical multiplexer carries the 2.048Mbps E1 signal as a whole frame transparently to the opposite end without modifying the frame structure, signaling or time slot content of the E1 on the user side, and the effect between the devices at the two ends is equivalent to a direct connection with a single E1 coaxial cable. The E1 interface of the IDM OMP8000 10Gbps multi-service optical multiplexer has a bit rate of 2.048Mbps, HDB3 line coding, a PCM30/31 frame structure, transparent transmission as the operating mode and a standard protocol compliant with ITU-T G.703, with an impedance selectable between 75 Ω and 120 Ω.

The value of E1 transparent transmission lies in not changing the existing service configuration: the SPC exchanges (stored program control switching equipment), telecontrol equipment or PCM multiplexers connected at the two ends do not need to be configured again, and the engineering side only needs to connect the optical path and the E1 cables. The IDM OMP8000 10Gbps multi-service optical multiplexer multiplexes E1 together with gigabit Ethernet, telephone and V.35 services into the same 10Gbps optical channel, so the E1 telecontrol channel and the office data network share one pair of optical fibers and no separate laying of optical fibers is required for each type of service. For government private network optical fiber communication solutions that need to carry voice and data at the same time, telephone optical multiplexers and gigabit network optical multiplexers from Raytrans can be deployed in combination to reduce the occupation of optical fiber resources.

How Is Uninterrupted Transmission Ensured on Weak Optical Links and at Field Sites?

With a receiver sensitivity better than -24 dBm together with a transmit optical power of -1~-10 dB, the IDM OMP8000 10Gbps multi-service optical multiplexer can maintain stable reception on long-distance lines with high link attenuation and on construction sections with many connectors and fiber adapters, reserving a usable optical power margin for the project. Communication interruption in field private networks is often caused by an insufficient optical power margin, and the receiver sensitivity specification together with the transmit optical power range determines how much line loss can still be tolerated between the two ends; therefore, calculating these two specifications together with the line loss during selection costs less than repeated troubleshooting afterwards.

The IDM OMP8000 10Gbps multi-service optical multiplexer supports two power supply modes, AC220V and DC-48V: at equipment rooms with AC power, mains power can be used directly, and at communication sites with only DC power, -48 V DC can be connected without additional inverter equipment. The device has an operating temperature of -20 °C to +50 °C and a relative humidity of 0 to 95% (non-condensing), with an overall power consumption of no more than 90 W, adapting to environmental conditions such as unattended equipment rooms and field cabinets that lack air conditioning. In military emergency communications vehicle solutions, this multi-service optical multiplexer can be enabled quickly by relying on the mature PDH optical multiplexer architecture, and with the optical multiplexer product showcase and technical support of Raytrans, it provides integrated access capacity for voice, data and video at emergency sites.

Application Scenarios of the Multi-Service Optical Multiplexer: Electric Power, Rail Transit and Field Private Networks

Electric Power and Energy Industrial Private Network

Energy sites such as substations, wind farms and photovoltaic power stations need to backhaul dispatch telephones, telecontrol data and the office network to the management unit. The IDM OMP8000 10Gbps multi-service optical multiplexer uses one pair of optical fibers to carry the E1 telecontrol channel, telephones and gigabit Ethernet at the same time, so the site side no longer needs to set up a separate optical multiplexer for each type of service. The device supports DC-48V power supply and can directly draw on the existing DC power supply of the substation, and its operating temperature goes down to -20 °C, adapting to the operating conditions of outdoor cabinets and unattended field equipment rooms.

Rail Transit and Expressway Communications

Railways, metros and expressways have distributed sites along the line at intervals of several kilometers, and the inter-station communication services cover three types: telephone, data and network. The two SFP optical ports A and B of the IDM OMP8000 10Gbps multi-service optical multiplexer can be configured as required, and each station along the line accesses telephone and Ethernet services nearby and backhauls them to the central equipment room in a unified way, so that multiple sites share one trunk optical fiber in chain networking. The E1 transparent transmission channel can be used to carry the channel services of the existing dedicated communication system, reducing the workload of service cutover and modification along the line.

Military and Government Field Private Networks

Field command posts, temporary training sites and emergency communications sites usually have no ready-made transmission resources and need to establish telephone, data and network channels within a short time. The IDM OMP8000 10Gbps multi-service optical multiplexer concentrates telephone, audio, 64Kbps data, V.35 and gigabit Ethernet in a single device, and using it in pairs enables multi-service communication over one pair of optical fibers, which facilitates vehicle-mounted transport and quick deployment. The V.35 interface can connect to devices such as routers, and the n×64Kbps rate configuration makes it easy to allocate bandwidth flexibly according to availability.

How to Select a Multi-Service Optical Multiplexer: Configuration and Optical Module Recommendations

For the selection of a multi-service optical multiplexer, first look at the service types and quantities, then at the transmission distance and the power supply environment, and finally check whether the interface standards are consistent with the existing equipment at both ends. The IDM OMP8000 10Gbps multi-service optical multiplexer is configured by service cards: gigabit Ethernet service cards are configured when the site is dominated by the data network, FXO/FXS voice channel cards when voice dispatching is dominant, and the corresponding service cards according to the number of channels when E1 or V.35 dedicated line transparent transmission is required; the types and quantities of service cards are subject to the manufacturer's technical documentation and commercial confirmation.

Optical modules are selected according to the actual optical fiber length, optical fiber type and line attenuation; the optical port of the IDM OMP8000 10Gbps multi-service optical multiplexer is an SFP pluggable structure, single-mode optical modules cover the 1310/1490/1550 nm wavelengths, and multi-mode modules can be used for short-distance cabling. The power supply mode is chosen between AC220V and DC-48V according to the equipment room conditions, and the operating temperature must cover the local extreme temperatures; for large-scale multi-site deployment, it is recommended to connect to SNMP network management to monitor the link and service status in a unified way. If a site originally used multiple single-function optical multiplexers to handle Ethernet, E1 and telephone services separately, switching to one IDM OMP8000 10Gbps multi-service optical multiplexer can reduce the number of devices and the occupation of optical fibers.
