    Publish time 2020-06-22 18:25    
Joinwit 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
