Optical Fiber Splitter
KSUN 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
