PRODUCT INFORMATION
820 nm
1A388
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 costeffective solutions. Its double-lens optical system results in optimum coupling of power into the fiber. And it matches the 1A354 PIN Photodiode.
