L7726/S7727
Emitter/receiver for 156 Mbps POF communications
L7726 and S7726 are designed for high-speed POF (Plastic Optical Fiber) communications. Both devices are molded into miniature plastic
packages with lenses, allowing easy and efficient coupling to a POF. S7727 uses a monolithic photo IC that ensures high resistance to external
noise and high reliability, and provides P-ECL voltage conversion output.
