Model 755MM-X Optical Transmitter
DWDM, 65 km, Low Distortion
Emcore’s Model 755MM-X is a directly modulated (DM) DWDM optical
transmitter specifically designed for CATV transmission over fiber links
up to 65 km.
The 755MM-X supports full 79-channel NTSC analog signal carriage
with RF bandwidth up to 870 MHz. The 755MM-X supports dual power
supplies as well as the SNMP network interface protocol.
The 755MM family of transmitter products is designed to support various
CATV transmitter applications with a common platform. 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.
Applications
