This series of digital video optical transceivers adopts digital video encoding and gigabit fiber optic transmission technology to achieve the joint transmission of video, audio, data, and switch level on a single core fiber optic cable.

This product consists of an optical node machine and an optical receiver. The node machine can transmit up to 2 forward videos and 1 RS485 data simultaneously, while the receiver can receive up to 16 videos and 1 RS485 data. A single fiber optic link can connect up to 16 nodes in series.

◆Fully digital fiber optic transmission platform, flexible configuration of multiple services on the same platform;

◆We can provide various ways for ordinary desktop, mini desktop, and centralized plug-in card racks;

◆Implement fiber optic bypass function when the node machine is powered off;

◆Can detect whether the remote device is powered off or disconnected when there is no light received;

◆PAL/NTSC/SECAM full standard compatibility, studio level transmission quality;

◆Provide bidirectional asynchronous data (forward and reverse);

◆Asynchronous data with a transmission rate of 110-115.200Kbps or higher;

◆Asynchronous data can be RS232/RS485/RS422/Manchester code;

◆The data interface and video interface provide three-level lightning protection function and can pass the ITU-T K.21 (10/700 μ S) common mode: 6KV impedance (40 Ω) test.

◆Fiber optic section

Physical interfaces: FC/PC, ST/PC

Transmission wavelength: 850nm/1310nm/1550nm

Transmission distance: multi-mode 0-2km, single-mode: 0-25km, 0-60km, 0-120km
