1 Product overview

The Wideband Optical Couplers (WOC) in the Flashlink range is all-optical power
splitters or combiners. These modules support WDM, CWDM and DWDM optical
schemes. The WOC is bitrate and format transparent; meaning SDI, Ethernet and
SDH/SONET is supported. The range consists of WOC-2-50-50, WOC-90-10 and
WOC-4-25.

The WOC-2-xx-xx is a 1:2 optical coupler available with two different coupling ratios.
And the WOC-4-25 is a 1:4 optical coupler, where the optical power is divided and
distributed equally to the four output ports.

A typical application for these units is multiple distribution and linear, tapped fiber optic
bus structures. The unit is passive and there is no need for power or control.

The WOC-2 optical coupler is available with two different split ratios:

 WOC-2-50-50-Mkll 50%-50% split ratio
 WOC-2-90-10-Mkll 90%-10% split ratio

The WOC-2 has two input/output ports and one common port.
A typical application for the WOC-4-25 is distribution to multiple locations of single or

multiple signals using WDM.
The WOC-4-25 optical coupler is made for wavelengths from 1260 up to 1620nm thus

covering the whole CWDM band.
