Vertical Cavity Surface Emitting Laser
OPV300, OPV310, OPV310Y,
OPV314, OPV314Y
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
• Burned in for communication level reliability
Description:
The OPV300 / OPV310 / OPV314 series are high performance 850nm Vertical Cavity Surface Emitting Laser
(VCSEL). The OPV300 and OPV310 are designed to be utilized for sensing applications as well as air
transmission of data. The OPV314 is designed for high speed communication links. The OPV310 / OPV314
combine all the performance advantages of a VCSEL with the addition of a power monitor diode for precise
control of optical power. The OPV310 and OPV314 have a back monitor photodiode used for optical power
management or optical reception for data communication applications.
The OPV300 / OPV310 have a flat lens while the OPV314 has a microbead lens. Refer to mechanical
drawings for details.
The high performance 850nm VCSEL is designed for applications where low current is required with high on-
axis optical power. These product’s combine features including high speed, high output optical power and
concentric beam making it an ideal transmitter for integration into all types of data communications equipment
as well as for reflective and transmissive switches.
Absolute Maximum Ratings (TA=25°C unless otherwise noted)
Operating Temperature Range 0°C to +70°C
Maximum Forward Peak Current, continuous 12 mA
Maximum Reverse Voltage 5 V
Max. Continuous Optical Power at 70° C 1.1 mW
Lead Soldering Temperature 260°C for 10 sec.
Storage Temperature Range -40°C to +100°C
Maximum Forward Current, pulsed (1 µs P.W., 10% D.C.) 48 mA
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.
(4) Using data points taken for slope efficiency above, delta L/delta I shall be calculated for
each adjacent pair of points.
Applications:
• Fiber Channel
• Gigabit Ethernet
• ATM
• VSR
• Intra-System links
• Optical backplane
interconnects
• Reflective sensing
• Interruptive sensing
• Long distance spot
illumination
Pb
RoHS
Additional laser safety information can be found on
the Optek website. See application bulletin #221.
Classification is not marked on the device due to
space limitations. See package outline for center-
line of optical radiance. Operating devices beyond
maximum rating may result in hazardous radiation
exposure.
