OPTEK VCSEL Sub-Assembly Achieves 2.5Gbps Data Rate In Fiber Optic Test Equipment



CARROLLTON, Texas (December 16, 2004) - Targeting design engineers who require high performance optical transmitters for high speed communications links in fiber optic test equipment, TT electronics OPTEK Technology has developed an 850nm VCSEL (vertical cavity surface emitting laser) packaged in an FC style receptacle capable of data transmission rates up to 2.5Gbps.

Designated the OPV314F/315F Series, these transmitters combine high speed data transmission with high output power, making them ideal for integration into fiber optic test equipment. They are compatible with high speed communications protocols, including: Fibre Channel, Gigabit Ethernet, ATM, and VSR (Very Short Reach).

"The OPV314F/315F Series incorporate a power monitor diode that maintains a constant output level," said Gary Cawley, OPTEK Business Development Manager "This active feedback enables precise control of the optical power output, which is critical in test and instrumentation applications."

In addition, Cawley explained, the OPV315F devices incorporate an attenuation coating on the inside surface of the lens, which reflects approximately 40 percent of the light, reducing the back reflection that can occur in short-run fiber connections commonly used in test equipment. This prevents over-driving of sensitive detectors and increases the current into the monitor diode.

The OPV314F/315F Series devices exhibit maximum forward peak current of 20mA, with reverse current of 35nA (max.). Forward voltage is 1.6V (min.) to 2.2V (max.), with maximum reverse voltage of 10V. Total coupled power output is 500µW for the OPV314F Series; 250µW for the OPV315F (tested at If = 7mA on 50/125µm fiber). Operating temperature ranges for the OPV314F /315F Series devices is 0°C to +70°C.

The OPV314F/315F Series devices are packaged in a screw-mounted nickel-plated brass FC style receptacle with a footprint of 0.5" (12.7mm) x 0.583" (14.8mm), with a board-mounted profile of 0.319" (8.1mm). The OPV314F/315F and the OPV314YF/315YF devices are optically and electrically identical, except for their pin-outs.

According to Cawley, OPTEK will provide assembly services for volume orders of the OPV314F/315F Series VCSELs, including PC board mounting, second-level wiring, module assembly, drive circuitry or other design services.

Typical pricing in 1,000-piece quantities for the OPV314F/315F Series devices is $25.00 each. Samples are available for immediate delivery, with production lead-times from stock to 6 weeks.
