Dense Wavelength Division Multiplexing (DWDM) is an optical multiplexing technology used to increase bandwidth over existing fiber networks. DWDM works by combining and transmitting multiple signals simultaneously at different wavelengths on the same fiber. The technology creates multiple virtual fibers, thus multiplying the capacity of the physical medium.
Litecore’s DWDM transceivers are designed for single-mode fiber and operates at a nominal DWDM wavelength from 1528.38 to 1563.86 nm (Channel 17 to Channel 61) as specified by the ITU-T. Except from being applied in long distance transmission, DWDM transceivers can also be used in switch to switch interface, switched backplane applications and router/server interface etc. DWDM transceiver supports up to 10 Gbps and can span a distance up to 120 km, which makes itself optimal for high-capacity and long-haul transmissions.
Data Center Solution
The bursting of traffic in the cloud data center has driven the operating rate of optical modules to escalate and accelerate and is currently in the process of upgrading from 100GB to 400GB or even 800GB. All the export data of the data center in the future will need to undergo internal massive calculations (especially the rise of internal traffic/export traffic of AI, VR, and other applications), the rapid increase of data transmission within the data center, and the flattened data center architecture. Litecore has greatly increased investment in technical R&D and production base for mass production of 25G, 100G, 200G, 400G optical modules.
After more than a decade of development, the SAN has matured and become the actual standard in the industry. However, the fiber-switching technologies of various vendors are not identical, and the server and SAN storage have compatibility requirements. Litecore provides optical module solutions that are compatible with switches and servers from various manufacturers to perfectly meet the compatibility requirements of different manufacturers.
