The Multicom MUL-1550TXEM-V-2 Externally Modulated Optical Transmitter is a state-of-the-art high-performance fiber optic transmitter specially developed for CATV signal distribution in HFC networks, and the long-distance transmission of cable phone and cable data. Optimized for a variety network applications, it is packaged in a convenient 1 RU housing. This two-laser transmitter couples the optical output powers of 7, 8, 9 and 10dBm each, with low optical linewidth resulting in unmatched performance.

The optical modulator, combined with proprietary predistortion circuitry, provides advanced features such as built-in field adjustable SBS control and electronic dispersion compensation allowing these transmitters to be quickly optimized in the field for any link or application without the need to procure specifically tuned transmitters. This affords the system designer a level of flexibility previously unknown in the CATV market place.
