Vertical Cavity Surface Emitting Laser in ST Optical Sub-Assembly OPV315AT, OPV315BT, OPV315YAT, OPV315YBT Features: • 850 nm VCSEL technology • High thermal stability • Up to 2.5 Gbps • Recommended for multimode fiber applications • Microbead lens • Pin out and attenuation options available on request • Burned in for communication level reliability • High optical coupling to MM fiber • ST* style receptacle Description: The OPV315AT and OPV315BT are high performance 850nm VCSEL packaged for high speed communication links. OPV315AT and OPV315BT combines all the performance advantages of a VCSEL with the addition of a power monitor diode for precise control of optical power. The OPV315YAT and OPV315YBT are identical electrically 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 concentric beam makes it an ideal transmitter for integration into all types of data communications equipment. Applications: • • • • • • Fibre Channel Gigabit Ethernet ATM VSR (Very Short Reach) Intra-system links Optical backplane interconnects Absolute Maximum Ratings (TA = 25° C unless otherwise noted) Storage Temperature -40° C to +125° C Operating Temperature 0° C to +85° C Soldering Lead Temperature 260° C for 10 Seconds Maximum Forward Peak Current, Continuous 12 mA Maximum Reverse Voltage 5V Maximum Forward Current, pulsed (1µs P.W., 10% D.C.) 48mA * - ST is a registered trademark of AT&T 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 RoHS OPTEK reserves the right to make changes at any time in order to improve design and to supply the best product possible.

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.
