Product Detailed
transmitters 1) 1 Channel Video signal, Single-mode 40km signal transmission, Multi-mode 5km; 2) F/O connector: FC


Fiber optic video transceivers

Comark fiber-optic video transceivers can simultaneously transmit 1-64 channels of

8-bit digitally encoded video / return or bidirectional data / unidirectional or bidirectional audio / Ethernet /

Telephone / Dry contact over one multimode or single-mode optical fiber. These multiplexers are typically

Used in applications where the cameras have P/T/Z capabilities. 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 environment.

Product characteristics8-bit digitally encoded and non-compression video transmission

directly compatible with NTSC, PAL, and SECAM CCTV camera systems and support RS-232,

RS-422, and RS-485 data protocols

Support any high-resolution video signal

Automatic compatible PAL, NTSC and SECAM video system

Power supply and other parameter state indication, which can monitor the operation condition of


Support no-damage regenerative trunk of video
