Node Video Optical Terminal

Global Tech GT-VO-2 series Node Optical Video Terminal integrates digital non-compressed video signal process, TDM and WDM technologies. Over only one fiber, GT-VO-2 can construct multi-node chain network and transport up to 16 channel digital non-compressed video signals simultaneously. GT-VO-2 consists of 2 types of NE: Remote CPE and Central Office. Remote CPE is designed as desktop standalone or chassis architecture, and Central Office type is standard 1U chassis design. Central Office product can provide 8/10 route video output, 2 route 10M/100M Ethernet with Layer-2 switch, 1/2 route shared data and 16 route point-to-point audio/data/switch signal optionally. Remote CPE device can provide 1~5 route video input, 2 route 10M/100M Ethernet interface with L2 switch, 1/2 route shared data and 5 route point-to-point audio/data/switch signal optionally.

l 8/10 channel digital non-compressed real-time video transmission.

l Line protection function: During Power Failure or NE Failure, Optical Line Protection function is automatically activated to ensure the link transmission next to the failed NE and enhance the system security and reliability.

l Remote CPE supports real-time software configuration。

l Maximum single span distance is up to 80km. And each node has a regeneration function, extending the whole link to the distance 800km maximum.

l Through Network Management System GUI and the whole network topology, configuration, fault and log management, increase the efficiency in deployment, maintenance and management for the end user.

l All series of products pass the Ministry of Public Security Type Test and get the Network Access License from the Ministry of Industry and Information Technology.
