JDSU introduces communications test solution
Mar 05, 2012 (Datamonitor via COMTEX) --
JDSU has introduced a communications test solution to help service providers and network equipment manufacturers prevent dropped calls and poor video quality over 4G/LTE and mobile backhaul networks due to ethernet synchronization issues. The new SyncE solution is available on JDSU's Optical Network Test, or ONT, platform.
As the communications industry transitions to ethernet to deliver 4G/LTE and mobile backhaul, base stations that aren't synchronized in frequency can disrupt mobile services and cause subscriber churn. Slow variations in signal timing (known as wander) as well as higher-speed variations in signal timing (known as jitter) create distorted signals for transporting voice, video and data over a network. This presents a challenge for communications service providers and contributes to poor service quality if not addressed properly, the company said.
The JDSU ONT-based SyncE solution offers jitter and wander testing in a single unit for 1G and 10G ethernet network deployments. It also delivers verification testing in the lab and can be used to diagnose and troubleshoot timing issues in the field following deployment, the company added.
"We've taken jitter and wander measurement techniques that have been proven for years and applied them to synchronized Ethernet for 1G and 10G for the first time," said Dr Lars Friedrich, vice president and general manager, JDSU Communications Test and Measurement business segment. "In order to roll out LTE and mobile backhaul, synchronous Ethernet is a critical element that every communications service provider and network equipment manufacturer needs to take into account. The ONT SyncE test solution enables them to avoid service-impacting issues in the field before deploying these services."
