High-Performance LED
Datacom, Intra-Office Telecom
This device is designed for Ethernet
100 Mbps and Intra-Office Telecom
applications and offers an excellent
price/performance ratio for cost-
effective solutions. Its double-lens
optical system results in optimum
coupling of power into the fiber. And
it matches the 1A354 PIN
Photodiode.
