Multi-mode Star/Tree Couplers
Description

Multi-mode Fused Fiber Star/Tree Couplers are designed by series-connecting basic units to eliminatethe modal sensitivity. It can be widely used in LON, PON and Optic-fiber Sensor systems.

Features
  • Low Excess Loss
  • Operating Bandwidth (800nm - 1600nm)
  • Good Environmental Stability
