How to Install Fiber Fast Connector: Essential Guidelines
September 14, 2023
Filter WDM modules are widely used in optical amplifiers and WDM networks. They separate or combine light at different wavelengths (1310nm/1490nm/1550nm) across a broad wavelength range.
This technology expands the capacity of a single fiber for bidirectional communication. Making it ideal for optical network upgrades and expansions, or for introducing new comprehensive business solutions.
Wavelength-division-multiplexing (WDM) is a fiber optic communications technology that multiplexes multiple optical carrier signals onto a single optical fiber.
There are three types of WDM systems: normal WDM, coarse CWDM and dense DWDM. The notation “xWDM” is commonly use to refer to these different WDM types.
It can save fiber resources, for example, a single-wavelength optical fiber system requires 32 optical fibers for 16 2.5Gb/s systems, while the WDM system only needs 2 optical fibers.
It is “transparent” to various business signals and can transmit different types of signals, including digital and analog signals. Synthesize and decompose signal is one of WDM functions.
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.
By using optical add-drop multiplexers (OADM) or optical cross-connect devices (OXC) at network nodes. It can build a dynamically reconfigurable optical network with high flexibility, high reliability and high survivability.

CWDM stands for coarse wavelength division multiplexing.
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.
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.
Passive Wavelength-Division Multiplexing.
