INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MT-1 multimode mini video
transmitter. Please take a few minutes to read these installation instructions in order to
obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The MT-1 operates as half of a transmitter / receiver pair for the transmission of
baseband NTSC, PAL, RS170, or RS343 video signals over a single multimode fiber
optic cable. It is designed to operate with the MR-10, MR-10M, RR-10, RR-10M, RR-20,
or RR-20M video receiver. The RR-20 contains the electronics and optics of two RR-10
units mounted on one printed circuit board to save space and reduce cost. The RR-20M
contains the electronics and optics of two RR-10M units mounted on one printed circuit
board.
The MT-1 converts a single video input into a single AM modulated optical output using
an 850 nm wavelength source. The 1, 10, and 20 Series product is designed to operate
over an optical loss budget range of 0 to 17 dB. The MT-1 operates on 50 um or 62.5
um multimode fiber. Refer to the data sheets for detailed performance specifications.
The small size and light weight of the MT-1 allows for direct mounting on the back of a
camera in an enclosure. For a wall mounted version please see the MT-10. For a rack
mounted version please see the RT-10 or RT-20.
