Dura 1x2 Optical Fiber Switch
DURA Series
Product Description
Oplink Dura 1x2 is magneto-optic-based fiber switch. The switch is built
based on Oplink’s patents US7035497, US6879746, ZL200310124977.6,
ZL200310124978.0. The switch has no moving parts. It is designed for use in
applications where billions of switching cycles are needed, such as network
monitoring.
