What Is the IDM-OXC Optical Cross-Connect Equipment?

The IDM-OXC optical cross-connect equipment is an optical layer scheduling device deployed in optical cable node equipment rooms. Its core function is to establish arbitrary non-blocking cross-connections between multiple input and output optical ports and then complete optical path switching according to the configuration issued by the intelligent O&M platform. As a professional bridge converter and optical cross-connect equipment, the unit is equipped with an OTDR detection module and a received optical power detection module, supports port received optical power detection, and has a cross-connect capacity of no fewer than 48 cores on each of the input and output sides.

Optical cross-connection means directly establishing a channel relationship between an input optical port and an output optical port at the optical layer; cross-connection relationships are issued centrally by the intelligent O&M platform, so O&M personnel do not need to plug or unplug pigtails on site in the equipment room. The IDM-OXC optical cross-connect equipment provides intelligent management of the optical distribution frame (ODF): arbitrary cross-connections between the transmission-side and user-side optical ports can be configured on the O&M platform to achieve rapid service scheduling and restoration, making it a representative product among optical path control devices.

In terms of structure, the IDM-OXC optical cross-connect equipment adopts a 19-inch 6U rack-mounted installation. Its optical interfaces are distributed in the rear panel area of the equipment, the interface type is an LC/UPC connector, and the management interface is a standard RJ45 network port that can be connected directly to the existing O&M network in the equipment room.

How Is the IDM-OXC Optical Cross-Connect Equipment Used in Private Network Optical Path Scheduling Scenarios?

The IDM-OXC optical cross-connect equipment is designed for private network optical path scheduling scenarios. At the core nodes of electric power private networks, rail transit communication, and military and government private networks, it takes on the centralized management and control of optical cross-connections.

Electric Power Private Networks: Centralized Management and Control of Optical Path Scheduling at Substation Core Nodes

Between substations and dispatch centers in an electric power private network, protection, dispatching and monitoring services are aggregated stage by stage along optical cables, and optical path adjustments traditionally depend on O&M personnel patching fibers manually in the equipment room. The IDM-OXC optical cross-connect equipment brings transmission-side and user-side optical ports into the same intelligent O&M platform; O&M personnel only need to configure cross-connection relationships on the platform to complete service scheduling, with a patching time of ≤3 minutes and an insertion loss of the cross-connected channel of ≤1 dB. For sites with dual power supplies and dual routes, the equipment can provide dual-backup or multi-backup protection for user-side optical ports and perform intelligent switching when the primary channel fails, ensuring service continuity between substations and dispatch centers.

Rail Transit Communication: O&M of Optical Cables Along the Line and Optical Paths at Stations

Optical cables laid along the line in rail transit communication carry signal, video and dispatch telephone services at the same time. Stations are distributed and inter-station distances are long, and optical layer fault location is time-consuming. The IDM-OXC optical cross-connect equipment supports targeted roll-call testing of fiber quality and periodic routine testing, and can detect fiber link transmission loss, connector loss and fiber link event points and generate a quality test curve; together with the OTDR detection module and port received optical power detection, it saves station and section O&M personnel from having to investigate section by section on site. The equipment adopts a 19-inch 6U rack-mounted installation, can be deployed in a station communications equipment room or a central equipment room along the line, and connects to the existing O&M network through an RJ45 network port.

Military and Government Private Networks: Optical Path Control and Multi-Route Protection at Core Nodes

Military and government private networks have strict requirements on the autonomy of optical path control and on service continuity, and the optical cable resources at core nodes need to support multi-route service protection. The intelligent fiber route planning function of the IDM-OXC optical cross-connect equipment recommends alternative route channels and scheduling plans in terms of total optical cable length, number of intermediate nodes, link loss, patching time and other dimensions, providing a reference for O&M decisions. The equipment offers power failure pass-through: after a power failure, cross-connection channels remain pass-through on the current route without service interruption. The patching process adopts an anti-tangle design, so pigtails are free of tangling and kinking, reducing the optical path risks caused by manual intervention.

What Differentiated Value Does the Optical Cross-Connect Equipment Bring?

The efficiency and reliability of the IDM-OXC optical cross-connect equipment come from a combination of four capabilities: 48-core cross-connection, power failure pass-through, dual-backup protection and patching in ≤3 minutes, as itemized in the table below.

Differentiation Point	Value for Private Network Users
48-core cross-connection: non-blocking cross-connection of 48 cores on each of the input and output sides	Input-side and output-side optical ports support arbitrary interconnection within a single unit, so hub sites no longer need manual patching to arrange a large number of optical paths
Power failure pass-through: after a power failure, the cross-connected channel remains pass-through on the current route	Existing optical paths are not interrupted during an equipment room power failure or power supply maintenance, and after power is restored the cross-connection relationships are still managed by the intelligent O&M platform
Dual-backup protection: dual-backup or multi-backup protection on the user side	Dual-backup or multi-backup on the user side; in the event of a failure the equipment performs intelligent switching to the backup equipment and services are restored quickly
Patching in ≤3 minutes: a single patching operation takes ≤3 minutes, with an insertion loss of ≤1 dB	Optical fiber scheduling is efficient and low-loss: optical path adjustments change from on-site plugging or unplugging to remote configuration on the platform, with a single operation kept within 3 minutes

IDM-OXC Optical Cross-Connect Equipment Selection and Deployment Recommendations

When selecting an optical cross-connect equipment, first verify the actual number of fiber cores required at the site, then confirm the protection mode, power supply conditions and O&M interfaces, so that the equipment matches the existing equipment room conditions. Ruiguang Jiyuan (Raytrans) has accumulated rich product showcase and deployment experience in the fields of bridge converters and optical cross-connect equipment, and can provide a reference for selection.

In terms of capacity, the input and output capacity of the IDM-OXC optical cross-connect equipment are 48 cores or more, and hub sites with a large number of optical cable cores should reserve capacity expansion margin. In terms of protection, sites carrying key services can configure dual-backup or multi-backup protection on the user side, with the equipment performing intelligent switching to the backup equipment when the primary equipment fails. In terms of equipment room conditions, the equipment adopts a 19-inch 6U rack-mounted installation, uses dual hot-standby power supplies with uninterrupted switchover, and provides a standard RJ45 network port as the management interface that can be connected directly to the existing O&M network.
