Package
Description
The OPV315 is a high performance 850nm VCSEL pack-
aged for high speed communication links. OPV315 com-
bines all the performance advantages of a VCSEL with
the addition of a power monitor diode for precise control
of optical power.
The OPV315Y is identical electrically and optically and
differs only in pin out. Refer to mechanical drawings for
details.
Features including high speed, high output power and
concentric beam makes it an ideal transmitter for integra-
tion into all types of data communications equipment.
Applications include:
Fibre Channel
Gigabit Ethernet
ATM
VSR
Intra-system links
Optical backplane interconnects

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

OPV315, OPV315Y Technical Data
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 1 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.
(4) Using data points taken for slope efficiency above, delta L/delta I shall be calculated for each adjacent pair of points.
