Notes:

1. Operating current is the average bias current required to meet the ER, rise/fall, and bandwidth specifications. The target

operating condition is 35 mA over threshold at high temperature, 30mA over threshold at RT.

2. Output power specification is defined into single-mode fiber(SMF 28).

3. TOSA would be capable of meeting other specifications when modulated over this ER range.

4. Maximum change in power as fiber is rotated by 360º.
