FS 10G CWDM/DWDM SFP+ Transceivers
Updated at Feb 7th 20221 min read
What is 10G CWDM/DWDM SFP+ Transceiver?
The 10G CWDM/DWDM SFP+ module is a sophisticated optical transceiver. By using wavelength-division multiplexing (WDM) technology – a fiber-optic transmission technique that allows different data streams to be sent simultaneously over a single optical fiber network – SFP+ modules can transmit data on discrete & specific wavelengths to improve density on existing fiber. It is designed to meet the increasing demands of high-speed data transmission in modern networking environments.
The CWDM module and the DWDM module are two types of modules that employ WDM technology. CWDM stands for Coarse Wavelength Division Multiplexing, while DWDM stands for Dense Wavelength Division Multiplexing. The key distinction between them lies in their wavelength intervals. 10G CWDM transceiver typically operates with a wider interval of 20nm between wavelengths, making it suitable for shorter distances. In contrast, 10G DWDM transceiver utilizes a much narrower interval of 0.8nm, allowing for a higher density of wavelengths. This characteristic makes it optimal for long-haul networks where maximizing bandwidth is crucial.

FS 10G CWDM/DWDM SFP+ transceivers offer enterprises and service providers a cost-effective solution in long-haul networks by supporting single-mode dual fiber applications with CWDM and DWDM wavelengths. We also support customised services to meet the individual needs of businesses.
