Model DM8000-U Optical Transmitter DATASHEET | MARCH 2012 FIBER OPTICS Direct Modulation, DWD, 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. Applications Video Signal Distribution in HFC CATV and FTTP nodes Supports CATV, QAM, and DBS Signal Carriage Replacement for Externally Modulated Transmitters Features Dual Redundant Power Supplies SNMP Network Interface Dual RF Inputs for CATV and DBS Available on 100 GHz Spaced ITU DWDM C-band Channels Optimized RF Intergration of Predistorter, Amplifiers, and Laser Complete, Efficient Laser Bias and TEC Control Circuitry 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 ± 3km. The selectable fiber length option has maximum SBS suppression of 20dBm. The DM8000 family of transmitter products is designed to support various CATV transmitter applications with a common platform. A 75 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 75 RF input supports frequencies up to 2700 MHz for FTTP, L-Band satellite, and wireless applications.
