Vertical Cavity Surface Emitting Laser in ST Optical Sub-Assembly 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 Absolute Maximum Ratings (TA = 25° C unless otherwise noted) The OPV314AT and OPV314BT are high performance 850nm VCSEL packaged for high speed communication links. OPV314AT and OPV314BT combines all the performance advantages of a VCSEL with the addition of a power monitor diode for precise control of optical power. Storage Temperature The OPV314YAT and OPV314YBT are identical electrically and optically and differ only in pin out. Refer to mechanical drawings for details. Maximum Reverse Voltage Operating Temperature Soldering Lead Temperature -40° C to +125° C -40° C to +85° C 260° C for 10 Seconds Maximum Forward Peak Current 30 mA 5V 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 include: ♦ ♦ ♦ ♦ ♦ ♦ Fibre Channel Gigabit Ethernet ATM VSR (Very Short Reach) 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.

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.
