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
