OFMS Series Multi-mode 1x1, 1x2 and 2x2
(Add/Drop) Optical Fiber Switches
OFMSMM Series
Product Description
Oplink’s OFMS series optical fiber switches offer industry leading perfor-
mance specifications with Telcordia compliant reliability. The multi-mode
switches are designed for use in protection, channel selection, fiber ring
network node bypassing and testing.
These patented opto-mechanical switches can be directly mounted on print-
ed circuit boards and feature less than 0.5dB 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.
