Single-mode Star/Tree Couplers

Description

The Single-mode Optic-fiber Tree /Star Couplers can couple the optical signals in the coupling area, and then re-distributes the light power. The key parameters include operating wavelength, bandwidth, and excess loss, coupling ratio, PDL and so on. All-optical fused couplers are proven having high performance in applications.

Features

Low PDL
Low Excess Loss
Good Directivity
Good Environmental Stability
Various types are optional
- Standard,Flattened,Broadband
- Tree,Star

Single-mode Star/Tree Couplers

Applications

Optical Fiber Communication Systems
