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.

(1) Large transmission capacity can save precious fiber resources. For example, for 16 2.5Gb/s systems, the single-wavelength optical fiber system requires 32 optical fibers, while the WDM system only requires 2 optical fibers.
(2) It is “transparent” to various business signals and can transmit different types of signals. For example, digital signals, analog signals, etc., and can be synthesized and decomposed.
(3) WDM technology is an ideal expansion means. There is no need to lay more optical fibers or use high-speed network components during network expansion. Any new business or capacity expansion can be introduced only by changing the terminal unit and adding optical wavelength.
(4) Build a dynamically reconfigurable optical network, using optical add-drop multiplexers (OADM) or optical cross-connect devices (OXC) at network nodes. It can form an all-optical network with high flexibility, high reliability and high survivability.

(1)CWDM: CWDM stands for coarse wavelength division multiplexing.
(2)DWDM: DWDM is short for dense wavelength division multiplexing. CWDM and DWDM use light to transmit data. Each light pulse transmitted through a fiber cable contains multiple light wavelengths that can be encoded with data from various sources. CWDM can handle up to 18 wavelength channels, while DWDM can handle up to 80.
(3)FWDM: The FWDM series is based on Thin Film Filter technology which is eco-friendly. The device combines or separates light of different wavelengths over a broad wavelength range. They offer low insertion loss, low polarization dependence, high isolation and excellent environmental stability.
(4)PWDM: Passive Wavelength-Division Multiplexing.
(5)AAWG:Athermal AWG(Arrayed Waveguide Grating), or AAWG, is based on silica-on-silicon planar technology. Fibconet provides a series of AAWG DWDM MUX/DEMUX with 24, 32, 40, 44, and 48 channels optional
