Description
Absolute Maximum Ratings (TA = 25° C unless otherwise noted)
The OPV214AT and OPV214BT are high performance
850nm VCSEL packaged for high speed communication
links. OPV214AT and OPV214BT combines all the performance advantages of a VCSEL with the addition of a
power monitor diode for precise control of optical power.
Storage Temperature
The OPV214YAT and OPV214YBT are identical electrically and optically and differ only in pin out. Refer to mechanical drawings for details.

NOTES:
(1) Threshold Current is based on the two line intersection method specified in Telcordia GR-468-Core. Line 1 from 6 mA to 8 mA.
Line 2 from 0 mA to 2 mA.
(2) Series Resistance is the slope of the Voltage-Current line from 8 to 12mA.
(3) Slope efficiency, is the slope of the best fit LI line from 8 mA to 12mA using no larger than .5 mA test interval points. Measured with a 50/125
µm fiber.
