Vertical Cavity Surface Emitting Laser in ST Optical Sub-Assembly OPV314AT, OPV314BT, OPV314YAT, OPV314YBT 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 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. The OPV314YAT and OPV314YBT are identical electrically and optically and differ only in pin out. Refer to mechanical drawings for details. This products 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.

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 m fiber. (4) LinearityUsing data points taken for slope efficiency above, data L/delta I shall be calculated for each adjacent pair of points.
