Model 755MM-U Optical Transmitter

DWDM, 20 km, Low Distortion, Wideband

Emcore’s Model 755MM-U 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 755MM-U supports full 79-channel NTSC analog signal carriage up

to 10 km. A combination of QAM, DBS, and reduced channel analog

CATV, are supported in links up to 20 km.

Applications

The 755MM family of transmitter products is designed to support various

CATV transmitter applications with a common platform. A 75Ω CATV RF

video input supports frequencies up to 870 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 75Ω RF input supports frequencies up to 2600 MHz for

FTTP, L-Band satellite, and wireless applications.
