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

Now that 40G/100G systems have become a reality, key transceiver vendors are working hard to provide optical CFP modules that require specific signal conditioning of their electrical interfaces in ord...

This article highlighted the increasing need for wireless service providers to turn to LTE to deploy mobile broadband networks beyond 3G, and examined how this transition to 4G manifests developing tr...

New trends such as deployments in multidwelling or multitenant units (MDU/MTUs) often include pre-engineered plug-and-play components with multiple connection points or, alternately, they can also be ...

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.

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...

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.

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...
