Red LED for optical link

L9534

Red LED for 125 Mbps optical link

L9534 is a LED ideal for high-speed POF communications. L9534 is sealed in a small plastic package with a lens, allowing easy coupling

to an FOP.

*3: Input is a pseudo-random bi-phase signal at 125 Mbps (NRZ signal conversion).

*4: Average value (duty ratio 50 %) measured by using a plastic fiber of φ1 mm. SI-POF and NA=0.5 (GH4001 made by Mitsubishi

Rayon).

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.
