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
