8 Ch HD-SDI Fiber Kit with Dual Aux for Analaog Audio or RS422/485/232 data or Contact closure

Extend HD-SDI or SD-SDI digital video signals long distances over single-mode fiber optic cable

Transport up to eight full rate HD-SDI digital video signals at 1.5Gbps each over a single strand of fiber cable up to 80km long.  In addition dual Aux ports provide additional capacity by adding up to 4 analog bi-directional audio, 2 full duplex RS-232/422 links, or 4 contact closure lines per Aux interface.  The transmitter inputs support any serial digital signal up to HD-SDI, including SD-SDI.  The F-M8SDI platform delivers more functionality and performance over a single fiber than has ever been available in off the shelf equipment.

Each of the 8 HD-SDI signals are fully isolated from each other and operate at a full 1.5 Gbps data rate.  Each channel carries its own embedded audio and ancillary data and operates as if it were the only signal on the fiber.  This is accomplished with CWDM technology.

The 8 channel platform offers the same 5 pin Aux port custom signal options as the two and four channel units.  However functionality is doubled by providing 2 independent Aux links that can be customized for 4 channel bi-directional or unidirectional audio, 1 or 2 duplex RS-232/422 links, or 4 line contact closure.

Product Features
  • Supports 8 Full HD-SDI @ 1.5Gbps or lower SDI
  • Transports embedded audio channels as well as SDI ancillary data
  • Return path serial RS-485 channel for controlling equipment on Tx end
  • Link alarm indicators on both Tx & Rx indicate a problem with the fiber
Locking Cables
FC fiber & BNC connectors make sure that the
cable is not accidentally pulled out of the equipment    
No Link Alarms
Link status alarm on both the transmitter
and receiver indicate when the link is not functional.
  Serial Data
   RS-485 return path sends serial data from the
    receiver back to the transmitter for device control.
