What does LWDM mean in an optical module

LWDM is short of LAN WDM (Local Area Network Wavelength Division Multiplexing). But navigating the alphabet soup of CWDM, DWDM, MWDM, LWDM, and SWDM can be daunting. Each offers distinct advantages tailored to specific network needs and budgets. By simultaneously transmitting multiple optical signals, each at a unique wavelength, through a single fiber, WDM optimizes bandwidth utilization. In 25G application scenarios, operators mainly adopt two schemes for 12-wave colored optical modules, namely MWDM and LWDM, with the following characteristics: • MWDM Scheme This scheme is derived from 6-wave CWDM, realized by offsetting each central wavelength of CWDM (1270nm-1370nm) by ±3. CWDM has 18 different wavelength channels, and the different wavelengths of each channel are separated by 20nm, using wavelengths from 1270 nm to 1610. Wavelength Division Multiplexing (WDM) is a technology used in optical fiber communications to increase data transmission capacity and speed.
