Ultra-mini 1x1, 1x2, 2x2 (Add/Drop)
Fiber-optic Switch
OFMSSM Series
Product Description
Oplink OFMS ultra-mini fiber-optic switches are ideal for module and system integration
where the unique unilateral input and output fiber configuration is preferred. These
switches are designed for use in re-configurable optical add/drop multiplexers, optical
cross-connect systems, and network switching for fault protection applications.
The opto-mechanical ultra-mini switch can be directly mounted on printed circuit board
(PCB) and offer the same excellent performance characteristics of Oplink’s standard
OFMS series switch products. The OFMS miniature switches are designed to exceed Tel-
cordia standards GR-1221 and GR-1073.
Oplink provides customized design to meet special control and applications. Also, Oplink
offers modular assemblies that integrate other components to form a full function mod-
ule or subsystem.

.
2) Switching time is defined as the time interval between electrical trigger and 90% of stable optical output.
3) A >20ms DC pulse is recommended for latching type of switch.
4) Short term is defined as less than 96 consecutive hours and less than a total of 15 days over a one year period.
