Things to Know Before Selecting CWDM SFP Transceivers

As an extension of wavelength division multiplexing (WDM), coarse wavelength division multiplexing (CWDM) is a technology that multiplexes a number of optical carrier signals onto a single optical fiber through the use of different wavelengths (i.e., colors) of laser light. A CWDM SFP (Small Form-factor…

Different Technologies Used in DWDM Multiplexer

Dense wavelength division multiplexing (DWDM) is an advancing fiber-optic transmission technology which combines multiple optical channels at different light wavelengths and then transmits them over the same optical fiber. Theoretically, the DWDM technology can multiplex hundreds and even thousands of separate wavelengths into a single…
