Filter WDM modules are extensively used in optical amplifiers and WDM networks. The device combines or separates light at different wavelengths (1310nm/1490nm/1550nm) in a wide wavelength range. It can expand the capacity of a single fiber to achieve bidirectional communication so that widely used in optical network upgrades and expansion, or introduce new comprehensive business, etc.

Wavelength-division multiplexing (WDM) is a fiber-optic communications technology that multiplexes several optical carrier signals onto a single optical fiber. Normal WDM, coarse CWDM, and dense DWDM are the three wavelength patterns used in WDM systems. Because of this tree of different WDM types, one of which is known as “WDM,” the notation “xWDM” is commonly used.

• Low insertion loss

• Low polarization related loss

• High wavelength isolation

• Stable function in different environment

• Compact structure
