FBT Optical Couplers Box










Description

Optic Network adopts unique bandwidth extension techniques (asymmetric craft) for the tri-windows couplers to change the characteristic of the wavelength and make tri-windows at 1310/1490/1550nm wavelength meet the precision requirements of the coupling ratio. This unit specially applies for the low-cost solution of " 3 in 1 network" and tri-wavelength bi-direction transmission with a single fiber in FTTx network.


Features

1) Low PDL

2) Low Excess Loss

3) Good Directivity

4) Good environmental Stability

5) Tri-operating windows


Applications

1) Optical Fiber Communication Systems

2) Optical Fiber CATV

3) Passive Optical Network (PON)

4) FTTx
