Red LED for optical link
L8045
Emitter for 50 Mbps optical link
L8045 is optical communication devices designed for POF (Plastic Optical Fiber) data links. L8045 is a highly reliable, high-
power LED that emits red light with a peak at 650 nm optimized for POF. A mini-lens is molded on the package for efficient coupling
to a POF. When used with our recommended driver circuit, a 50 Mbps transmitter can be configured at low cost.

Note:
· A bypass capacitor (0.1 µF) and another capacitor (4.7 µF) are connected between Vcc and GND at a position within 3 mm from
the lead.
· The center of the optical fiber is aligned with the center of the lens on the package. The distance between the fiber end and the
lens is 0.1 mm.
