How are the 8 groups of physically isolated gigabit Ethernet accessed?
Physical isolation means the 8 groups of gigabit Ethernet are completely isolated at the data plane and do not share bandwidth, with each port group forwarding independently at interface wire-speed. On the Ethernet side, the transmission rate is 10M, 100M, or 1000M, the standard protocol supports IEEE802.3, and the operating mode supports full/half duplex/adaptive; a traffic burst on one channel will not squeeze the bandwidth of other port groups.
To access the 8 groups of physically isolated gigabit Ethernet, simply allocate services to different port groups by security domain: one group of ports for the office network, one group for the video surveillance network, and one group each for the production dispatching network and telecontrol data. The networks are invisible to one another and do not need to rely on switch VLAN partitioning. Isolation is implemented at the hardware channel level, so servicing one port group does not affect the operation of other services, making it suitable for an access point that simultaneously carries multiple independent security domain networks. This design approach of an integrated service access device is the practical result of Raytrans's experience in government private network optical fiber communication solutions.
How is a 1+1 ring network protection optical multiplexer networked?
A 1+1 ring network protection optical multiplexer means the device uses two optical ports to connect to the opposite end and to adjacent sites on the ring, so that when an optical path in any section fails, services are automatically switched over to the other optical path. The IDM OMP8000 8-channel isolated gigabit integrated service optical multiplexer provides two SFP optical interfaces, A and B, and can form point-to-point, chain network, ring network, or 1+1 protection networks, keeping services running through a single point of failure.
The difference between the three common networking topologies lies in site distribution: point-to-point deploys one device at each end of the link, directly connected via a pair of optical fibers, and is suitable for dedicated line access between two equipment rooms; a chain network connects sites along the line one level at a time, suitable for strip-shaped scenarios such as highways and railways; a ring network connects multiple sites end to end, so that when a fiber break occurs in any section, services can be rerouted from the other side.
The IDM OMP8000 8-channel isolated gigabit integrated service optical multiplexer can also be used in combination with our company's IDM MSAP-G3CP integrated service optical fiber transmission equipment to achieve complex networking, allowing devices with different access capacities to coexist on the same optical fiber network and selecting the corresponding ports according to site service volume. For government private network optical fiber communication solutions that require hybrid networking of MSAP and PCM equipment, this capability is particularly practical.

How is PCM mutual backup between the optical fiber and the first E1 implemented?
PCM mutual backup between the optical fiber and the first E1 gives the same set of narrowband PCM services two transmission paths at the same time, one over the optical fiber channel and one over the E1 channel, so that when an abnormality occurs on the optical path side, the services can be carried by the E1 channel instead. During configuration, the IDM OMP8000 8-channel isolated gigabit integrated service optical multiplexer can configure PCM services as mutual backup between the optical fiber and the PCM services on the first E1, giving narrowband services an extra layer of fallback.
The two layers of protection have different roles: the 1+1 protection of the optical ports handles automatic switchover at the optical path layer, while PCM mutual backup handles channel fallback at the service layer. With both in place, the impact of optical cable maintenance, construction damage, or an abnormality in a single optical module on narrowband voice channels and data services is further reduced, and sites can maintain continuous operation of narrowband services even under unattended conditions.

Typical Application Scenarios
Energy and Electric Power: Private Networks for Substations and Distribution Stations
Substations, distribution stations and the booster stations of new energy stations simultaneously carry three types of services: dispatch telephone, telecontrol data and video surveillance. Most sites are unattended and their equipment rooms have no air conditioning. The IDM OMP8000 8-channel isolated gigabit integrated service optical multiplexer uses a pair of optical fibers to carry all three types of services out at once, so the site side no longer needs to set up a separate optical multiplexer for each type of service.
The E1 channel and the PCM equipment back each other up to carry telecontrol and protection information, the FXS/FXO cards connect dispatch telephones and hotlines, and the 8 groups of physically isolated gigabit Ethernet separately carry the video surveillance network, the office network and the production network. The device supports dual power supply of DC-48V and AC220V, and can directly draw on the existing direct current power supply at the station; its operating temperature is -20℃~+50℃, adapting to the operating conditions of outdoor cabinets and unattended station buildings.
Rail Transit: Communication and Surveillance Along the Line
Stations along railways, metros and expressways are several kilometers apart, and the inter-station services include telephone, data and network. Access points are scattered and equipment room conditions are limited. The IDM OMP8000 8-channel isolated gigabit integrated service optical multiplexer forms a chain network or ring network according to site distribution, and each station along the line accesses services nearby and then backhauls them to the central equipment room over the trunk optical fiber.
In the ring network topology, if a fiber break occurs in any section, services along the line can be rerouted from the other side; video surveillance exclusively occupies one group of isolated gigabit ports, while dispatch telephones and telecontrol data use their own interfaces, so they do not affect each other during link maintenance. The device can also perform hybrid networking with IDM MSAP-G3CP, organizing the integrated service access devices in the central equipment room and the remote access devices on the same optical fiber network.

Figure 4: Schematic of service access deployment of IDM OMP8000 in station cabinets at substations and along rail lines
Military and Government: Field Private Networks and Emergency Sites
Field command posts, temporary training sites and emergency communications sites usually have no ready-made transmission resources, and telephone, data and network channels need to be established in a short time. The IDM OMP8000 8-channel isolated gigabit integrated service optical multiplexer concentrates telephone, audio, 64Kbps data, V.35 and 8 groups of isolated gigabit Ethernet into one device. Used in pairs, the terminals can enable multi-service communication over a pair of optical fibers, which facilitates vehicle-mounted transport and rapid deployment.
The V.35 interface can interconnect with devices such as routers, and the n×64Kbps rate configuration method makes it easy to allocate flexibly according to available bandwidth; dual power supply and wide-temperature design adapt to field equipment rooms with limited conditions, and SNMP network management makes it easy for O&M personnel to remotely keep track of device status at sites via the existing IP network, reducing field duty and inspection frequency.
