The 120,000-square-meter office building has optical entrance and copper exit: LC in each weak-current room on each floor is fully equipped with ODF terminals, jumpers are standardized when entering the room, and two-optical and four-electrical SFP transceivers are flexibly connected to tenants.

In the welding and assembly workshops, 46 industrial computers were renovated with optical interfaces, 10G dual-optical network cards were used for visual inspection, and 485 optical transceivers were used to solve frequency conversion interference and bit errors.

Signal interconnection between the 3 studios and the main control: 4-channel HDMI + network + two-way audio multi-service optical transceiver non-compressed transmission, large-screen monitoring and directing calls are directly connected through one fiber.

The 100G backbones in the three computer rooms are fully photonic, old multi-mode links with frequent failures are replaced, 100G LR4 single-mode optical modules and LC are fully equipped with ODFs, and the cutover is zero-interruption.

For local metropolitan area network capacity expansion, more than 12,000 SFP+ 10G dual-fiber optical modules were delivered in batches with matching LC and fully equipped with ODF. They were tested one by one and shipped according to site labeling.

6 tunnel 118-channel video and 485 control signal return management sub-center: 4-channel video + reverse 485 optical transceiver and multi-service model combination, stable image under strong tunnel interference.

Optical fiber backhaul for 320 additional road monitoring points: card rack optical transceivers are centrally aggregated, POE transceivers provide first-line power supply, and armored pigtails are used to cope with roadside construction environments.

Replace telecontrol, voice and data channels with optical fiber: The 485 optical transceiver isolates the ground potential difference, dispatches the traffic optical transceiver and the ODF terminal to be deployed in an integrated manner, and communication interruption accidents are cleared.
