Direct-Modulation, DWDM, Low Distortion, Wideband

EMCORE’s Medallion 8000 is a directly-modulated DWDM optical transmitter specifically designed for wideband applications that require both CATV and DBS signals to be transmitted over up to a 30 km length of fiber. This facilitates networks designs that use a single transmitter to carry multiple signals.

The Medallion 8000 supports full 79-channel NTSC analog signal and/or a combination of QAM, DBS with reduced channel analog CATV. It can be selected as a fixed fiber length option to support a fixed length from 0 – 10 km, 5 – 15 km, 10 – 20 km and 15 – 25 km with 18 dBm SBS suppression maximum, or it can be ordered as a fiber length selectable option. This option allows the user to set the Medallion 8000 for best optimized CSO at any fiber length from 0 – 30 km with 1 km increments. At the selected fiber length, the unit can perform within specification with a fiber length of ± 3 km. The selectable fiber length option has a maximum SBS suppression of 20 dBm.

The L-type/D-type/S-type/F-type/N-type Medallion 6000 Series

This product line is a family of state-of-the-art high performance 1550 nm externally modulated CATV fiber optic transmitters optimized for varying network applications. Packaged in convenient 1RU housing, this line of optical transmitters couples high optical output powers, up to 11.0 dBm, with low optical line width resulting in unmatched performance. The optical modulator, combined with proprietary pre-distortion circuitry, provides superior CTB and CSO performance with SBS suppression levels of greater than 21 dBm. Advanced features such as built in field adjustable SBS control and electronic dispersion compensation allow 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.
