Wavelength Division Multiplexing (WDM) has the power to handle high loads of data transfer. For example, Facebook and Microsoft are working together to build a trans-Atlantic submarine cable that will handle up to 160 Tb/s - this is acheivable through WDM. So how does WDM work? Well, WDM uses different wavelengths of laser light to combine several optical carrier signals into a single fiber. This multiplies the carrying capacity of the fiber. Historically, WDM has been limited to singlemode fiber. This technology is exceptional, but data centers typically cannot use it, since data center applications often require multimode fiber.
CommScope is proud to announce wideband multimode fiber (WBMMF), an innovative new technology that transfers the power of WDM to multimode fiber. WBMMF can carry at least four times more traffic than OM4. How does WBMMF work? It provides at least four lanes within a single fiber, which allows for the use of four data streams operating at 10G each or 25G each. Plus, the signals are multiplexed at each end into the fibers. And even better - because WBMMF provides multiple separate lanes, it enables efficient Bi-directional (BiDi) traffic for proprietary applications.
One of the perks of CommScope WBMMF, besides that it expands the power of WDM to multimode applications, is that it's backwards compatible with legacy optical equipment and connectors; you don't have to replace everything you already have in order to implement WBMMF. By the end of 2016, the TIA is expected to approve standard 942-B, which recognizes WBMMF as an allowed and recommended fiber for data center migration.
