Model DM8000-U Optical Transmitter
Direct Modulation, DWDM, Low Distortion, Wideband
Emcore’s Model DM8000-U 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 30km length of fiber. This
facilitates networks designs that may use a single transmitter to carry multiple
signals.
The DM8000-U supports full 79-channel NTSC analog signal and or a
combination of QAM, DBS with reduced channel analog CATV. The DM8000-U
can be selected as fix fiber length option to support a fix length from 0 – 10km,
5 – 15km, 10 – 20km and 15 – 25km with 18dBm SBS suppression maximum,
or it can be ordered as the fiber length selectable option. This option allows the
user to set the DM8000-U for best optimized CSO at any fiber length from 0 –
30km with 1km increment. At the selected fiber length for the fiber length
selectable option, the unit can perform within specification with the fiber length
tolerant of
suppression of 20dBm.
The DM8000 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 2700 MHz for FTTP, L-Band satellite, and wireless
applications.
