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. Other output power range is possible per customer request.

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.

5. Measured with an optical receiver with a 3.125 Gb/s filter

6. Rise and fall times are measured 20-80%

7. Resistance is measured between ITH + 10mA and ITH + 20mA

8. Tracking error is defined as the coupled power difference at Tmax or Tmin (relative to 25°C) where the back monitor current,

Imon, is held constant at the value found at 25°C at I=Iop.
