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