Recently, EB-LINK completed the delivery of video optical transceiver orders for highway monitoring and reconstruction projects in the province, covering multi-channel backhaul links at points along the line, service areas and tunnel management stations. This is another batch delivery of the company's long-standing surveillance fiberization project type.

Points are scattered over long distances and difficult to return

The cameras are scattered along the highway, the distance between the single point and the management center is far, and there are vibrations and temperature differences in the environment. The traditional coaxial return transmission picture deteriorates significantly as the distance increases, so the fiber can only be laid in sections. The tunnel section also needs to be compatible with the existing monitoring system, and the opening window is usually only arranged during night maintenance periods, which puts forward higher requirements for the plug-and-play and one-time opening rate of the equipment.

Configuration idea: multi-channel aggregation plus reverse control

The project uses multiple baseband video optical transceivers to gather cameras at each point.8-channel video + 1-channel reverse 485 data video optical transceiverTaking into account the control backhaul of the dome camera, a pair of fibers carries video and data at the same time. The receiving end is deployed in the computer room of the management office, and the labels and numbers are unified to facilitate inspection and replacement. This idea is consistent withOptical fiber project for vehicle monitoring system in highway tunnel in a provinceInheriting the experience of fiber opticization, on-site shelves are put on the shelf in batches according to areas and opened road by road. Spare parts machines are also reserved at key points at the same time, and faults can be replaced and repaired immediately.

Delivery packages and follow-up arrangements

This batch of equipment has completed the channel lighting test one by one and left the factory with records. The spot models in the warehouse will be shipped first, and subsequent batches will arrive in batches according to the construction progress of each road section to avoid waiting for materials on site or having nowhere to store them. EB-LINK provides remote debugging support for construction units. You can call 0755-83179002 on working days to answer technical questions to ensure the smooth progress of the phased opening.
