OPV314AT 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 OPV314AT 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:
- Fiber channel
- Gigabit Ethernet
- ATM
- VSR (very short reach)
- Intra-system links applications
- Optical backplane interconnects 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 upon request
- Burned in for communication level reliability
- High optical coupling to MM fiber
- ST style receptacle 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 5 V Maximum Forward, Current, pulsed 1 µs P.W., 10% D.C.) 48 mA 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.
