The Versitron  versivision series video multiplexer simultaneously transmit sixteen channels of 8-bit digitally encoded broadcast quality video over one multimode or singlemode optical fiber. The units are directly compatible with NTSC, PAL, and SECAM CCTV camera systems. These video multiplexers are typically used in applications that have fixed cameras.

Plug and play design ensures the 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 16-channel transmitter unit at the camera end of the link, connected via a single fiber optic cable, to a 16-channel receiver unit at the monitoring end of the link. Devices are available for either standalone or rack-mount installation.

Key Features :

• 8-Bit Digitally Encoded Video Transmission
  
• Compatible with NTSC, PAL, or SECAM CCTV
  
• Transmit up to 30 Km without Optical Attenuation
  
• Wide Optical Dynamic Range
  
• No EMI, RFI Cross Talk or Video Distortion
  
• LED Indicators for Instant System Monitoring
