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.
