WDM Filter Technology

As an unprecedented opportunity to dramatically increase the bandwidth capacity, WDM(Wavelength Division Multiplexing) technology is an ideal solution to get more bandwidth and lower cost in nowadays telecommunications networks. WDM Filters can separate or combine optical signals carried on different wavelengths in a cost-effective manner. Splitters versus Filters One issue with WDM-PON(Passive Optical Network) is that there is no industry-accepted definition. WDM-PON is an…

DWDM System Helps Expand the 10GbE Network

Dense Wavelength Division Multiplexing (DWDM) network is regarded as a feasible solution to achieve long-distance fiber expansion. DWDM system, with the channel density of 96, has much narrower channel spacing than CWDM system, which allows extremely high utilization of a single fiber strand to pass up to many clients. 10G DWDM SFP+ modules can support a link length of up…
