• Manufacturer Part Number: dm8000-u-010-079-l75-21-107-sa-aa
• Description: Model Dm8000-u Optical Transmitter Direct Modulation, Dwdm, Low Distortion, Wideband
• Manufacturer: Emcore Corporation

Model DM8000-U Direct Modulation Optical Transmitter
RF Characteristics
The following specifications are reference at 25C. The CATV test receiver is the Emcore receiver, model 7820A, with
responsivity of 0.95 A/W (at 1550 nm). Test fiber is single mode, Corning SMF-28 (or equivalent) with 0.25dB/km maximum
loss (at 1550 nm). In order to prevent reflection-induced distortion, the transmitter subassembly must be connected to an
optical cable with discrete reflections < -55 dB and distributed reflections < -30 dB.
