What is Wavelength Division Multiplexing (WDM)?

WDM is a technology approach that allows for the combining ("mux") of multiple individual light wavelengths (signals/channels) from multiple lasers on a single fiber using a passive component for transmission to another location. At that receiving location, WDM components then work in the reverse, demultiplexing ("demux") the combined wavelengths back into individual signals and routed to their respective receivers.

Mobile Backhaul - Strategies for Increasing Bandwidth to Cell Sites

Posted by OJ Johnston on Mon, Jul 22, 2013 @ 17:07 PM

As the use of mobile applications and services that require increasingly more bandwidth continues to grow, wireless service providers must find cost-effective and efficient methods for meeting the bandwidth demand. Legacy transport networks are no longer capable of adequately serving today’s cell sites. Newer technologies such as GPON, WDM-PON, and Ethernet over CWDM/DWDM are all well-suited to cost-effectively address the growing bandwidth needs of wireless service providers. Regardless of the technology used, M2 Optics’ SplitLight product is an integral part of the solution.
