PRODUCT INFORMATION

1A225

880nm

Single-Mode Datacom

High-Performance LED

Compared with lasers and ELEDs,

this device can reduce device costs in

single-mode Ethernet networks. And

since it’s packaged in a hermeti-cally

sealed can, it achieves high reliability

even in harsh operating environ-

ments.
