How JDSU is solving Challenges in Telecoms through Test & Measurement


By Zia Askari

With more and more devices being connected to the global telecoms infrastructure, according to experts, 50 billion connected devices are expected by 2020.

This is sure to mobilize enormous wired and wireless data traffic demand and massive network management challenges.  In this environment, network architectures, management solutions, and business models are evolving rapidly.

This evolution creates opportunities for carriers, service providers, network equipment manufacturers, enterprise Web 2.0 players, and key enablers like JDSU to capitalize on these trends. JDSU offers the ability to provide network and service enablement tools and solutions that help plan, deploy, and manage networks and services irrespective of the architecture, network or service type.


“JDSU’s Network and Service Enablement business segment maintained its number one position in field test instruments, gaining share and turning in strong performances in fiber, broadband access, and wireless network enablement solutions, all of which saw solid growth year on year. In service enablement, we have invested heavily to support our customers’ moves to SDN and NFV technologies and to increase software content,” explained, Sandeep Kapoor, Country Manager, JDSU India.

Solving the Challenge of Passive Inter Modulation

With increasing pressure and density of traffic, today’s telecom networks experience a lot of challenges such as PIM, a form of distortion caused by cables and connectors and this becomes a big challenge for operators looking forward to providing seamless quality of service and experience for their customers.

“We know firsthand that advances in network and service enablement techniques can help proactively resolve issues before they impact service quality.  In fact, JDSU is behind an innovation that allows technicians to test a cell site for PIM. JDSU introduced the industry’s first PIM-detection capability that lets a single, portable test analyzer detect UL PIM across the full spectrum for any technology,” he adds on.

Generally, the keys to test in this area is to enable service providers in several areas: when interference is reported, for example, cell technicians should be able to detect whether it is caused by PIM before dispatching a specialist troubleshooting team with expensive PIM analyzers.

“This will significantly reduce resolution time, and bring customers back online faster.  Simplifying troubleshooting is also key – for example, displaying two spectrum measurements at once on a field test instrument, allowing simultaneous monitoring of downlink and uplink traffic. The result is minimized test time and quick decision making.  The ability to test advanced LTE services is important as is the ability to verify multimedia broadcast multicast services (MBMS) control signals and traffic allocation, enabling the efficient delivery of broadband services and the generation of additional revenues,” he describes.
