Model 755M Optical Transmitter

RF Characteristics

DATASHEET| AUGUST 6, 2008

The following specifications are reference at 25C. The test receiver responsivity of 0.95 A/W (at 1550 nm) and an

equivalent noise current of 7pA/rt(Hz). 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.
