In a design of the 2x2 re-configurable optical
Wavelength Cross-connect (WXC) switch, we have
investigated the minimum number of reflections and
minimum number of used fiber Bragg gratings (FBG)
filters. The number of circulators and FBGs add to the
loss of transmitted power and cost of the optical network.
In minimizing the number of reflections in an optical
switch with four re-directional circulators, all possible
directions of the circulators with all possible placement of
the FBG in the switch are considered. We have addressed
these issues for possible practical applications in large re
configurable optical cross-connects (OXCs) routers.
