Medallion 8100 Series DOCSIS 3.1 L-EMLTM Externally-Modulated CATV Transmitters

C-Type/J-Type/F-Type/S-Type Transmitters
The Medallion 8100 series is a family of state-of-the-art, high-performance, DOCSIS 3.1 compliant 1550 nm externally-modulated CATV transmitters that leverages a breakthrough optical device innovation at their core, the Linear Externally Modulated Laser (L-EMLTM), invented, developed and manufactured exclusively at EMCORE. The L-EMLTM device consists of a high power, low-noise, narrow linewidth laser combined with a proprietary highly-linearized modulator in a monolithic assembly. It enables long distance optical link performance approaching traditional lithium niobate-based externally-modulated transmitters, but is more cost-effective for its targeted applications.

Packaged in a convenient 1RU housing, the 8100 series optical transmitters couples high optical output powers, up to 12.0 dBm, with low optical linewidth resulting in unmatched performance. The unique EMCORE optical modulator, combined with proprietary predistortion 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 allows 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.

The MEDALLION 8100 series provides options to accommodate a broad range of network architectures. The series includes C-Type, J-Type, F-Type and S-Type transmitters.
