Bi-direction Video + Data/Alarm + Audio + Telephone + 100M Ethernet  fiber optical transceiver
Bi-direction Video + Data/Alarm + Audio + Telephone + 100M Ethernet Series products adopt the most advanced international technology of digital video and optical fiber transmission, performing synchronous, undistorted, uncompressed and high quality signal transmission over all kinds of optical fiber.
This Fiber Optical Transmitter & Receiver can be easily used in the normal operation by virtue of LED indication of working status, and without any electric or optical regulation on site. It can be installed independently or installed in 2U/4U rack.
Features:
Card-type or Stand-alone type for your choice; suitable for concentration management in 4U Racks
10 –digit coding and non-compression video transmission
supporting any high –resolution video signal
automatically compatible with PAL, NTSC and SECAM video format
Supporting video intact regenerative relay, the video transmission can be reach above 200km
Supporting advanced SNMP standards, realise long-distance web-controlling
LED indication of power and other parameter status, monitoring real-time operation
Modularized and industrialized design ensuring reliability and flexibility
