FBT Optical Couplers----PON Optical Coupler
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
- Low PDL
- Low Excess Loss
- Good Directivity
- Good environmental Stability
- Tri-operating windows
Applications
- Optical Fiber Communication Systems
- Optical Fiber CATV
- Passive Optical Network (PON)
- FTTx
