Description:
The OPV315AT and OPV315BT are high performance 850nm VCSEL packaged for high speed communication
links. OPV315AT and OPV315BT combines all the performance advantages of a VCSEL with the addition of a
power monitor diode for precise control of optical power.
The OPV315YAT and OPV315YBT are identical electrically and optically and differ only in pin out. Refer to
mechanical drawings for details.
This product’s combination of features including high speed, high output power and concentric beam makes it an
ideal transmitter for integration into all types of data communications equipment.

NOTES:
(1) Threshold Current is based on the two line intersection method specified in Telcordia GR-468-Core. Line 1 from 4 mA to 6 mA.
Line 2 from 0 mA to 0.5 mA.
(2) Series Resistance is the slope of the Voltage-Current line from 5 to 8 mA.
(3) Slope efficiency, is the slope of the best fit LI line from 5 mA to 8 mA using no larger than .25 mA test interval points. Measured with a
50/125 µm fiber.
(4) Linearity—Using data points taken for slope efficiency above, data L/delta I shall be calculated for each adjacent pair of points.
