Fiber Optic Design Guide - Maite y Mario

The MIBR/SIBR-M3T-25 receivers, used with the MIBT/SIBT-M3T-25 transmitters,
provide a high-quality system for transferring up to five video channels per
multimode fiber with complete EMI immunity via fiber optics. The units offer
exceptional analog bandwidth from 5 MHz to 250 MHz, allowing transmission of
all sub-band channels, low-band channels, FM channels, and mid-band channels.
The lowest high-band channels may also be accommodated.
The best performance will be achieved when the channel plan is designed to
contain all of the channels within a single octave of bandwidth. When used in
conjunction with a VCR, a camcorder, or cable television feed, an example system
can receive TV channels 2 through 6, along with their sound carriers, over
a distance of 3 km or more at 1310 nm, over a single 62.5/125 µm multimode
fiber.
The carrier-to-noise (CNR) ratio is typically 47 dB at low optical loss. The units
also offer exceptional performance at lower channel loadings. This product is
recommended for use with 62.5/125 µm fibers only. A minimum fiber bandwidth
of 250 MHz is required.
