| Vertical Cavity Surface Emitting Laser in TO-46 Package Features * * * * * * * * * 850nm VCSEL Technology Data rates up to 2.5 Gbps High thermal stability Low drive current/high output density Narrow and concentric beam angle Recommended for multimode fiber applications TO-46 package with microbead lens Burned in for communication level reliability Monitor photodiode Description The OPV314 is a high performance 850nm VCSEL packaged for high speed communication links. OPV314 combines all the performance advantages of a VCSEL with the addition of a power monitor diode for precise control of optical power. The OPV314Y 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 integration into all types of data communications equipment. Applications include: Absolute Maximum Ratings (TA = 25 C unless otherwise noted) Storage Temperature Operating Temperature Soldering Lead Temperature Maximum Forward Peak Current Maximum Reverse Voltage Max. Continuous Optical Power at 70C -40 C to +100 C 0 C to +70 C 260 C for 10 Seconds 20 mA 10 V 1.1 mW 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 September 2003 Issue 3.3 Optek Technology, Inc.

Line 1 from 4 mA to 6 mA. Line 2 from 0 mA to 0.5 mA. Series Resistance is the slope of the Voltage-Current line from 5 to 8 mA. 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. Using data points taken for slope efficiency above, delta L/delta I shall be calculated for each adjacent pair of points.
