Red LED for optical link
L7726
Emitter for 156 Mbps POF communications
L7726 is 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.
Features
l Red LED for POF data link
l 650 nm emission suitable for POF communications
l High-speed response: fc=100 MHz Typ.
l High output power: Po= -1.5 dBm (IF=30 mA, φ1 mm, POF)
l Designed to be used with S7726
Applications
l Plastic optical fiber communications (FA, office machine,
home automation, LAN)
l Data transmission in locations subject to high
electromagnetic noise
