Model 755M Optical Transmitter
DWDM, up to 20 km, Low Distortion, Wideband
Emcore’s Model 755M is a directly modulated (DM) DWDM optical
transmitter specifically designed for wideband applications that require
both CATV and DBS signals to be carried over up to 20 km of fiber. This
facilitates networks designs that may use a single transmitter to carry
multiple signals.
The 755M supports full 79-channel NTSC analog signal and or a
combination of QAM, DBS with reduced channel analog CATV. The
fiber length the 755M can support is up to 20km.
The 755M family of transmitter products is designed to support various
CATV transmitter applications with a common platform. A 75
CATV RF
video input supports frequencies up to 1002 MHz. Integrated within the
transmitter design are Emcore’s low chirp control, noise suppression
circuitry, and patented predistortion technology to provide outstanding
performance with any of Emcore’s wide range of cooled broadband
lasers. A second 75
RF input supports frequencies up to 2600 MHz for
FTTP, L-Band satellite, and wireless applications.
