DATASHEET| AUGUST 6, 2008  
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.  
Applications  
°Video signal distribution to  
HFC CATV and FTTP nodes  
The 755M 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 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 75Ω RF input supports frequencies up to 2600 MHz for  
FTTP, L-Band satellite, and wireless applications.  
°Supports CATV, QAM, and  
DBS signal carriage  
°Replacement for externally  
modulated transmitters
