Broadcom eval kit AFBR-POMEK2204, supports 2W laser, AFBR-POL2120. The kit, which incorporates the 2W laser, features a controllable current source to adjust the laser light output.
A full power-over-fiber link is conveniently achieved by coupling to one of Broadcom’s optical power converters (AFBR-POC204L or AFBR-POC206L). Broadcom’s highly efficient optical power converters are well known for delivering 100% galvanically isolated power in industrial applications. With the 2W laser, Broadcom now provides the complete solution. The AFBR-POMEK2204 delivers up to 2W of laser light output power that is controlled via an easily accessible 16-pin connector.
A 5V voltage supply is all that is needed to operate the evaluation kit. The laser drive current can be controlled to ramp up to constant or pulsed power and maintain that power. The laser pigtail is terminated with an FC connector that matches Broadcom’s optical power converter.
The 2W laser falls under Class 4 (IEC60825-1), and the kit should never be operated without an optical power converter connected at the end of the fiber pigtail. Using a closed loop with continuous feedback, Class 1A laser classification is feasible.
