Product Description

Features

Applications

Notes:

1) IL @23°C over all wavelength range and all SOP. Add

0.25 dB (max.) to IL values for dual 1x2 and 0.4dB (max)

for dual 2x2 Add/Drop over operating temperature

range.

2) Excluding connectors.

3) Current is derived from driving voltage and coil resis-

tance. Pulse of >20 ms duration is recommended for

latching switch.

4) The mechanical tolerance is ±0.2 mm on all package

dimensions unless specified otherwise.

OFMS Series Single Mode Dual 1x2 and 2x2

Add/Drop Optical Fiber Switches

OFMSSMD Series

Oplink OFMS series single mode dual 1x2 or 2x2Add/Drop optical fiber switches function

as two 1x2 or 2x2 Add/Drop switches that are simultaneously switched together. The

dual switch is housed in the similar package as the Oplink OFMS series standard switches

while maintaining superior optical performance.

The dual 1x2 or 2x2 Add/Drop switch are built on Oplink’s patented opto-mechanical

switches having a unique prism design to improve the switch repeatability and stability.

The switches are designed for use in re-configurable optical add/drop multiplexers, opti-

cal cross-connect systems, and network switching for fault protection applications. One

dual 1x2 (2x2Add/Drop) switch device can be used to substitute two 1x2 (2x2Add/Drop)

switches. In addition, the dual 1x2 switches can be used as building blocks to construct

1x4 and 1x8 switches while significantly reducing the mechanical foot-print.

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.
