Description

FiberLogix use unique environmentally stable Thin Film technique to make the 1310/1490/1550 WDM. It can be used to combine or split 1310/1490/1550 nm two wavelength optical signals. High power handling capability can be achieved through unique pigtail processing and high quality AR coating. WDM couplers are widely used in PoN, CATV optical network upgrade. WDM can customised to have high isolation up to 35dB for both passband and reflection band.

FiberLogix offers a number of connector options with different housing dimensions. The housing dimension and optical performance can be tailored to meet customer's requirements.
