4Ch Digital Fiber-Optic Transmission Equipment
Model: T4VFC-20K
Brief introduction:
The fiber multiplexers simultaneously transmit 1-72 channels of digitally encoded broadcast quality video over one multimode or single mode optical fiber. The modules are directly compatible with NTSC, PAL or SECAM CCTV camera systems. Plug and Play design ensures ease of installation and operation. Electronic and optical adjustments are never required. The units incorporate LED indicators for monitoring the power and video operating status. A typical installation utilizes a 1-72 channels transmitter unit at the camera end of the link, connected via a single fiber optic cable, to a 1-72 channels receiver unit at the monitoring end of the link. Devices are available for either standalone or rack-mount installation.
