WideBand Mulitmode Fiber Meets the Need for Higher Speeds

Is there any limit to user demand for bandwidth in the enterprise? Industry leaders are forecasting an increase in demand at a compound annual growth rate (CAGR) of nearly 25 percent over the next five years. In order to support this increased level of traffic, standards organizations are constantly working to support higher speeds for the transmission of data. In the past, transceiver vendors traditionally have increased the speed of their devices in order to achieve higher speeds. Later, transmission schemes using parallel fibers were adopted. At some point, however, simply increasing the number of fibers for each new speed becomes unreasonable, in part because the cable management of parallel fiber solutions, combined with the increasing number of links in a data center, is much more difficult.

Now, focus has moved to the optical fiber carrying the signal. A new multimode fiber under development will extend the ability of conventional OM4 fiber to support multiple wavelengths using short wavelength division multiplexing (SWDM). Referred to in the industry as “wideband” multimode fiber (WBMMF), this SWDM-enhanced fiber is expected to maintain the cost advantages of multimode fiber for short distance applications, up to 300 meters (m) or more. One such fiber is LaserWave® FLEX WideBand Multimode Fiber from OFS, expected to be commercially available by the end of 2015.|Is there any limit to user demand for bandwidth in the enterprise?
