Vertical Cavity Surface Emitting
Laser in FC Optical Sub-Assembly
OPV314F, OPV314YF, OPV315F, OPV315YF
• 850 nm VCSEL technology, up to 2.5 Gbps data rate
• High thermal stability with Microbead lens
• High optical coupling to MM fiber with FC style receptacle
• Recommended for multimode fiber applications
• Burned in for communication level reliability
The OPV31XF and OPV31XYF are a high performanc e 850nm Vertical Cavity Surface Emit ting Laser (VCSEL) package d
for high speed communic ati on li nk s. OPV31XF combines all the performance adv antages of a VCSEL with the addition of
a power monitor diode for precise control of optical power. The VCSEL is a current dev ice assuming the forward voltage
drop, from 1.6 to 2.2 volts, is achieved.
The OPV31XF and OPV31XYF are electrically and optically identical, they differ only in pin out. Refer to the charts below.
The OPV315 devices have an attenuation coati ng on the interior surface of the lens. The coating reflects about 40% of the
light reducin g noise in special applicat io ns, prev entin g overdriving of sensiti ve detectors and doublin g monitor current.
These prod uct’s include a combination of feat ures inc luding high sp eed with high outpu t power and a concentric beam there
by making it an ideal transmitter for integration into all types of data communications equipment .
Applications include:
• Fibre Channel
• Gigabit Ethernet
• ATM
• VSR (Very Short Reach)
• Intr a-s ystem li nks
• Optical backplane interconnects.

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.
