Triplexor
A Triplexor is an optical component made of silica with a silicon wavefront which utilize the Mach-Zehnder interferometry design to tweak fiber-bragg grating.
A Triplexor is also a short name for a Triplex Alternator. Often found as a 3 input, 2 or 3 output, solid state alternator that equalizes output load operational time. A load select switch can permit the Triplexor to be used as a duplex alternator until system expansion requires Triplex operation.
