Description
The OPV310 is a high performance 850nm VCSEL packaged
for high speed communication links. OPV310 combines all
the performance advantages of a VCSEL with the addition of
a power monitor diode for precise control of optical power.
The OPV310Y is identical electrically and optically and differs
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 communica-
tions equipment.
Applications include:
Fibre Channel
Gigabit Ethernet
ATM
VSR
Intra-system links
Optical backplane interconnects
.

= 25 C unless otherwise noted)
Additional laser safety information can be found
on the Optek website. See application #221.
Classification is not marked on the device due to
space limitations. See package outline for
centerline of optical radiance. Operating devices
beyond maximum rating may cause devices to
exceed rated classification

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 0.25 mA test interval points.
(4) Using data points taken for slope efficiency above, delta L/delta I shall be calculated for each adjacent pair of points.
