Medallion 8000 Series 1550 nm
Directly-Modulated Transmitter
DATASHEET | MAY 2013
FIBER OPTICS
RF Characteristic
The following specifications are reference at 25°C. 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 0.25 dB/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.
