Abstract
A system and method for filtering are disclosed. The system and method include providing first, second, third and fourth fibers for carrying a first, second, third, and fourth optical signals, respectively. The method and system also include providing a holder, a filter, and a first wedge assembly. The holder is for receiving the first fiber, the second fiber, the third fiber, and the fourth fiber therein. The filter is for filtering the first optical signal, the second optical signal, the third optical signal, and the fourth optical signal to provide a first filtered optical signal, a second filtered optical signal, a third filtered optical signal, and a fourth filtered optical signal. The first wedge assembly is disposed between the holder and the filter. The first wedge assembly is for directing the first optical signal towards the filter in a first path, for directing the second optical signal toward the filter in a second path, for directing the third optical signal towards the filter in a third path, and for directing the fourth optical signal toward the filter in a fourth path.
