1 Product overview
The Flashlink 2x1 Wideband Optical Switch and 2x2 Wideband Optical Switch are fiber
optical SPDT (Single Pole Double Throw) changeover modules for use together with the
WOS-C1 connector module.
Figure 1: Block diagram of the WOS-2x1 and WOS-2x1L
Figure 2: Block diagram of the WOS-2x2 and WOS-2x2L
Typical applications for these units are selective routing of optical signal paths without opticalto-electrical conversion and Automatic Protection Switching (APS). The units are controlled
via Flashlink GYDA control system or the GPI interface.
The optical switches operate in the 2nd and 3rd optical windows (1310nm and 1550nm)
The WOS-2x1 has two input/output ports and one common port.
The WOS-2x2 has two input ports and two output ports.
The product is available in four different versions all delivered with WOS-C1 connector
