Description
LAN WDM Module, 12 Wavelengths in O-band for LANWDM
LWDM, known as Local Area Network Wavelength Division Multiplexing, is based on Ethernet channel wavelength division multiplexing LAN WDM technology with a channel spacing of 200 to 800GHz, between DWDM (100GHz, 50GHz) and CWDM (approximately 300 THz). LWDM is in the O-Band(1260~1360nm) wavelength range and utilizes 12 wavelengths specifically ranging from 1269nm to 1332nm band with a wavelength interval of 4nm(1269.23, 1273.54, 1277.89, 1282.26, 1286.66, 1291.1, 1295.56, 1300.05, 1304.58, 1309.14, 1313.73, 1318.35nm).
LWDM channel wavelengths are located near zero dispersion, with small dispersion and good stability. At the same time, LWDM can support 12 x 25G, with increased capacity, which can further save optical fiber.
LWDM is often used for short distance communication, typically for distances of up to 10km, offering lower equipment and deployment costs. It is commonly employed in various settings such as enterprise intranets (LAN), offices, and campus networks to enhance internal communication efficiency. Leveraging LWDM technology allows for effective utilization of fiber optic network resources, enabling swift data transmission between multiple devices while adapting flexibly to diverse LAN topologies and requirements.
