VIDEO DISTRIBUTION - Broadcast Fiber Optical Switch


The major driver for optical switching in video is the growth of fiber in the broadcast plant and the high bandwidth requirements of uncompressed HDTV signals.

Video distribution applications supported by Trinity include:
  • Inter-facility tie lines
  • Remote fiber switching
  • Line protection
  • High density port switching via CWDM or DWDM
  • Satellite uplink management
  • High performance RF-over-fiber applications
  • Mobile production vans
  • Management of cable head-end fiber trunks
  • Secure communications or video networks
  • Sharing expensive post-processing equipment

The Polatis Trinity All-Optical Routing Switch provides remote control and management of high-bandwidth audio, video and data signals for broadcast, post production, outside broadcast and satellite applications. Trinity switches enable routing of intra- or inter-facility fiber in high-definition video networks and are available in sizes from 4x4 up to 192x192 ports to suit a wide range of applications. Routing via optical fiber offers many benefits when compared to coax cable. The all-optical switch core has no Optical-to-Electrical-to-Optical (OEO) conversions which enable protocol-independent switching of all data rates and video formats.

This assures maximum flexibility since Trinity works with all existing and emerging video standards and you will not need to replace the switch when the transmission format is upgraded. To the left are a few of the sample video distribution applications of the Trinity switch.

  • The Trinity optics are fully bi-directional and can be used with single channel or multi-wavelength CWDM and Dense Wavelength Division Multiplexing (DWDM) video formats.
  • The Trinity All-Optical Video Routing Switch provides an unprecedented ability to control and manage high bandwidth video and audio signals for a wide range of broadcast applications.
  • Trinity expands the capabilities of today's broadcast infrastructure to meet the needs of existing and future video standards.
  • Optical fiber permits transmission over far greater distances than coaxial cable and has much lower cross-talk and signal distortion.
  • The Trinity All-optical switching enables the signal to be routed with universal fiber interfaces capable of handling virtually any audio and video signal, whether analog or digital.
  • The Trinity Series supports virtually all protocols and feed rates, including AES, SMPTE- 276M, 259M, and 292M, ASI/DVB, NTSC, PAL and QAM.
  • Trinity switches are currently deployed in numerous video switching applications such as the U.S. White House and government systems for satellite uplink and secure video routing.
