The F-1MSDI-L-2TX is a mini Fiber Optic Transport unit that is utilizes and extra loop out SDI connector on the transmitter for monitoring and for additional screening. The matching receiver F-1MSDI-L-2RX uses the same technology as the transmitter so you can acutally have 2 SDI outputs on the receiving end of the Fiber. This allows for easy access to redistribute a primary Fiber Cable that needs to be split to two SDI outputs.


It allows you to transmit  HD or SD-SDI as per SMPTE 424M-2006, 292 and 259, with or without embedded audio and data, as well as DVB-ASI over one single mode or multimode fiber. Signals are equalized and re-clocked prior to fiber optic transmission. The  transmitter features a re-clocked and equalized SDI loop through and the  receiver features two re-clocked and equalized SDI outputs. You need both the  transmitter F-1MSDI-L-2TX and  receiver F-1MSDI-L-2RX, units sold seperately.

The F-1MSDI-L-2TX/RX Series is compliant with SMPTE 297-2006

The F-1MSDI-L-2TX Series is immune to pathological signals over the entire budget link and operating temperature range.
