Description
The OPV215AT and OPV215BT are high performance
850nm VCSEL packaged for high speed communication
links. OPV215AT and OPV215BT combines all the per-
formance advantages of a VCSEL with the addition of a
power monitor diode for precise control of optical power
and about 30% optical attenuation for noise suppresion.
The OPV215YAT and OPV215YBT are identical electri-
cally 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 optical attenuation make
it an ideal transmitter for integration into all types of data
communications equipment.
Applications include:
Fibre Channel
Gigabit Ethernet
ATM
VSR (Very Short Reach)
Intra-system links
Optical backplane interconnects

This product is classified as 1M per EN/IEC60825-1/
A2:2001. The output from class 1M products must
not be viewed directly using optical magnifiers.
Additional laser safety information can be found on
the Optek website. See application bulletin #221.

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 mA to 12 mA.
(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
m fiber.
