receiver. Please take a few minutes to read these installation instructions in order to obtain the
maximum performance from this product.
FUNCTIONAL DESCRIPTION
The MR-940C-SL operates as half of a transmitter / receiver pair for the transmission of four
channels of high performance digital NTSC, PAL, RS170, or RS343 video signals. The MR-
940C-SL is designed to operate with the MT-940C-SL or RT-940C-SL video transmitter over
one singlemode fiber optic cable.
The MR-940C-SL de-multiplexes four video input signals from a high speed serial data stream.
This serial data stream is detected on a 1310 nm wavelength. The 940C-SL Series product is
designed to operate over an optical loss budget range of 0 to 21 dB. Refer to the data sheets for
detailed performance specifications.
This unit is contained in a rugged aluminum housing with internal dc voltage regulation. The
detachable terminal blocks and LED indicators provide for easy installation and monitoring of
video and power.
The MR-940C-SL is designed for mounting as a modular stand alone unit. For a rack mounted
version please see the RR-940C-SL.
