Doped Fiber Combiner, MPSC(N+1)x1

Doped fiber combiner combines 1 or 2 pump power source into a doped fiber directly. The splicing point is behind the coupling region, which has two advantages over standard combiner:

1) Customer only needs splice one time with doped fiber at combiner signal side.
2) The coupling region is behind splicing point, the isolation (backward signal to pump) is much lower than normal passive combiner to protect pump LD.
