OFMS Series Single Mode 1x1, 1x2 and
2x2 Add/Drop Optical Fiber Switches
OFMSSM Series
Product Description
Oplink’s OFMS series optical fiber switches offer industry leading performance
specifications with Telcordia compliant reliability. These switches are designed
for use in re-configurable optical add/drop multiplexers, optical cross-connect
systems, and network switching for fault protection applications.
These patented opto-mechanical switches can be directly mounted on printed
circuit boards and feature less than 0.35dB typical insertion loss. Oplink’s unique
prism design improves the switch repeatability and stability. The OFMS switches
are GR-1221 and GR-1073 qualified.
Oplink provides customized design to meet special control and applications.
Also, Oplink offers modular assemblies that integrate other components to form
a full function module or subsystem.
