By deploying properly engineered SBCs at the edge of their networks, NSPs can be confident that their networks are secured and that QoS is guaranteed. However, before deploying SBCs, NSPs should ask t...

To enhance troubleshooting tools for technicians and network engineers, EXFO has introduced packet-capture and decode capabilities to its extensive datacom portfolio.

With new ROADM deployment and 10G/40G/100G, there is a shift in the requirements to test CD and PMD in metro areas. Today, CD and PMD testing need to be optimized for both metro and core networks.

The growth of data-centric services, along with the growth of the social Internet and multimedia applications, has prompted wireless service operators to shift toward packet-based Ethernet/IP technolo...

As next-gen networks employ ROADM and/or multiple-bit/symbol advanced modulation formats, use of traditional OSNR measurements leads to either over—or under—evaluation of the OSNR.

As the service offering becomes more complex, network engineers and field technicians are required to respond to more troubleshooting service calls that require them to rapidly pinpoint, analyze and r...

Depending on bandwidth requirements and the amount of subscribers sharing the network costs, coarse wavelength division multiplexing (CWDM) has proven to be cost-effective for the ever-increasing mobi...

This article examines the key technologies and approaches required to reach requirements, especially in the access network, using OFDM, higher-order modulation schemes, advanced antenna technologies a...

Several high-bandwidth networks have recently been upgraded to include ROADMs to improve efficiency and flexibility. ROADMs allow networks to remotely change the amount of dropped or added wavelengths...
