Medallion 8000 Series 1550 nm Fiber Optic Transmitter

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.
