HENGSION Digital Non-Condensing Video Optical Transceivers can simultaneously transmit 1-128 channels of 8 bit/10 bit composite video signals, reverse or bidirectional data(Rs485/232/422), unidirectional or bidirectional audio, Ethernet, Telephone, dry contact, E1 signals over one multimode or single-mode optical fiber……


The video optical transceivers are typically used in applications with fixed or PTZ cameras. Plug and Play design ensures the ease of installation and operation. Electronic and optical adjustments are never required. LED indicators are provided for instantly monitoring system status. Devices are available for either standalone or rack-mount installation, which is suitable for different working environments. It is now widely used in security monitoring and control system, highway, Traffic Control Photographic System, automation and intelligent residence etc.


The function of network management is optional, and the running status of the system can be monitored by inserting just one network-managing card.





● 8 / 10 bit digitally encoded and non-compression video transmission

● Available for monitoring the running status of the system with the LEDs indicating parameters status of power, link and video

● Directly compatible with NTSC,PAL,SECAM CCTV camera systems and support RS232, RS485, RS422, and Manchester code

● Transmission distance can reach 120km without relay in single mode

● Industrial-level design with SMT techniques
