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

Extend HD-SDI or SD-SDI digital video signals over long distances with 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 of SDI to Fiber than has ever been available on 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.This Unit provides a multiple SDI over Fiber channels, each one carries their 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 fiber multiplexer 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.

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.
  • Supports 8 Full HD-SDI @ 1.5Gbps or lower SDI
  • Transports  embedded 2 audio channels on each SDI signal
  • 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

Question and Answers

The H-8MSDI-TX/RX is a perfect and convenient solution for transporting up to 8 HD/SD-SDI signals over a single fiber optic cable. The unit supports SDI up to 1080i/59.94/60Hz.

If you need support for SDI up to 3G SDI, which is 1080p/59.94/60Hz, we have a CWDM solution available. In this solution, each SDI signal is converted to its own optical wavelength using separate lasers and then combined together over one fiber. However, please note that due to the requirement for 8 wavelengths, the solution, the F-8SDI-3G-TX/RX, is more expensive. You can find more information about it here: Link to CWDM SDI Solution.

Unfortunately, we do not offer demos, but we do have a 30-day return policy. In any case, if the devices do not work for you, you can return them for a full refund.

We specialize in Fiber Optic signal transport and optical multiplication. Our devices are widely used in many stadiums, including exclusive use by the bigest Hhockey, footbol and socer  organizations
