Focal Multiplexer Product Line

903 Multiplexer

Fiber optic multiplexers

903 multiplexers provide highly reliable fiber-optic transmission of video and data signals in demanding environments. A modular Eurocard design and a wide range of supported video and data formats ensure the flexibility needed for easy system configuration. Individual data channels can be mixed and matched with a variety of plug-in interface modules. Advanced optical multiplexing (CWDM, DWDM) enables system expansion to 32 video and 256 data channels as well as additional high data rate signals such as HDTV (HD-SDI), ECL for advanced sonars and Fast Ethernet. Integrated diagnostics and software provide real time display and logging of all critical parameters.

Features

  • Compact, modular, 3U sub-rack
  • Highest quality digitized video
  • Wide range of supported video and data formats
  • Robust protection on I/O lines
  • Singlemode and multimode fiber options
  • Automatic fiber switching option
  • Extensive diagnostics monitors power system, video, data, temperature and fiber optic link

Benefits

  • Easily reconfigured at card level and individual channel level
  • Diagnostics verifies health of umbilical and tether cables
  • Continually updated with the newest data formats, including HD-SDI, IEEE-1394, and Gigabit Ethernet, to provide an extended upgrade path (custom interfaces available)
  • Successful installation assured by factory acceptance tests at temperature extremes and 20 years of experience providing technical support for fiber optic systems
