10G CWDM SFP+ 80km Module

         X-Krama's 10G CWDM SFP+ is a low-cost WDM transmission technology for the access layer of the

metropolitan area network. The 10G CWDM SFP+ optical module adopts CWDM technology, which can combine

optical signals of different wavelengths and transmit them through one optical fiber through an external wavelength

division multiplexer, thereby saving fiber resources. At the same time, the receiving end needs to decompose the

complex optical signal using a wave decomposition multiplexer. The 10G CWDM SFP+ optical module is divided

into 18 bands, from 1270nm to 1610nm, separated by 20nm between each two bands.         

        Compared with the traditional TDM method, the 10G CWDM SFP+ has speed and protocol transparency, which

makes it more suitable for the development of high-speed data services in the metropolitan area network. There are

many different protocols and services at different rates in the metropolitan area network. CWDM provides transparent

transmission channels with different rates on a single fiber, such as Ethernet, ATM, POS, SDH, etc., and CWDM is

transparent. The sex and add/drop multiplexing functions allow the user to directly go up and down a certain

wavelength without converting the original signal format. That is, the optical layer provides a transport structure that

is independent of the business layer.
