Single-mode optical modules are similar to multimode optical fibers
Single-mode optical modules are best for long distances and fast speeds. They use a thin fiber. Singlemode and multimode SFP modules are two primary categories of hot-swappable optical modules used in optical networks.

Single-mode fiber uses a 9/125 µm core/cladding structure that supports only one propagation mode, which minimizes modal dispersion and allows signals to travel tens of kilometers with low attenuation. Multimode fibers have larger cores (typically 50/125 µm or 62.

What does CWDM mean for optical modules
A CWDM SFP module is an optical transceiver that uses Coarse Wavelength Division Multiplexing (CWDM) technology to transmit multiple data channels over a single strand of single-mode fiber, helping networks expand capacity without deploying additional fiber. Compared to dense wavelength division multiplexing (DWDM), its wavelength spacing is coarser (typically 20nm), hence the.
