The Dual Fiber to Dual SDI Reversible Module from Theatrixx Technologies is designed for the Theatrixx 8-Bay Reversible Rackmount Frame for Video Converters. It can be inserted in the 8-bay frame from either direction, allowing the inputs/outputs to be positioned at the front or rear, as your application requires. The module features an enclosed design with no exposed PCBs and is protected against static shock, dust, and general wear and tear.
