OFMS Series Multi-mode Dual 1x2 or 2x2
Add/Drop Optical Fiber Switches
Oplink’s OFMS series optical fiber switches offer industry leading perfor-
mance specifications with Telcordia compliant reliability. The new switch
functions as two 1x2 or 2x2 Add/Drop multi-mode switches that are simul-
taneously switched together. The dual 1x2 or 2x2Add/Drop switch is housed
in the similar package as the Oplink OFMS series standard switches while
maintaining superior optical performance.
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.
