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.


DDT-D-T/R3201DSSFA Video Optical Transceivers can simultaneously transmit 32 channels of 8 bit composite video signals and reverse rs485 via 1 single core fiber. you can choose to add 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 function of network management is optional, and the running status of the system can be monitored by inserting just one network-managing card.
