DWDM optical modules use different wavelengths to multiplex multiple optical signals into a single optical fiber. This operation does not consume any power. These optical modules are designed for high-capacity, long-distance transmission, with rates up to 10Gbps and working distances up to 120km. At the same time, DWDM optical modules are designed according to the Multilateral Agreement (MSA) standard to ensure a wide range of network equipment. DWDM optical modules on the market usually include: DWDM SFP, DWDM SFP+, DWDM XFP, DWDM X2 and DWDM XENPAK optical modules.
DWDM optical modules support pluggable and tunable, there are 40 commonly used channels to choose from, this result has greatly reduced people's demand for independent pluggable modules. According to different requirements, DWDM optical modules have different channel spacings such as 0.4nm, 0.8nm and 1.6nm, which can support long-distance transmission up to 100km, and can be used as an effective solution to solve the problem of line bandwidth expansion.
DWDM SFP optical modules can be used for amplified DWDM networks, Fibre Channel, fixed and reconfigurable OADM ring network topologies, Fast Ethernet, Gigabit Ethernet and other optical transmission systems.
The DWDM SFP+ optical module conforms to the 10GBASE-ZR/ZW standard and can be used for 10G optical cables.
DWDM XFP optical module, DWDM X2 optical module and DWDM XENPAK optical module are usually used in 10G Ethernet, 10G Fibre Channel, SONET (Synchronous Optical Network) and SDH (Optical Transmission Equipment) and other applications.
In addition, these DWDM optical modules can also be used for switch-to-switch interfaces, switching backplane applications, and router/server interfaces.
