JDSU debuts jitter measurement capability for Synchronous Ethernet

JULY 27, 2010 -- JDSU (NASDAQ: JDSU) (TSX: JDU) has introduced a new jitter feature for the JDSU Optical Network Tester series (ONT-503, 506 and 512). The module makes the ONT as the first and only jitter analysis tool able to conduct both jitter and wander measurements on 10-Gigabit Ethernet Synchronous Ethernet (SyncE) devices and systems, JDSU asserts.

JULY 27, 2010 -- JDSU (NASDAQ: JDSU) (TSX: JDU) has introduced a new jitter feature for the JDSU Optical Network Tester series (ONT-503, 506 and 512). The module makes the ONT as the first and only jitter analysis tool able to conduct both jitter and wander measurements on 10-Gigabit Ethernet Synchronous Ethernet (SyncE) devices and systems, JDSU asserts. These capabilities are designed to help to ensure reliable signal and network performance of mobile backhaul networks for the delivery of high-quality bandwidth-intensive services such as video.

The new JDSU ONT jitter capability is designed to help address the tasks of characterizing both the jitter and wander performance of SyncE circuits so that timing and synchronization functions can be maintained without signal degradation or network performance problems.

"As demand for high-bandwidth services such as video continues to grow, consumers have a tremendous appetite for a high-quality experience -- whether they are watching it from home, on the Internet, or from a mobile device," said Lars Friedrich, vice president and general manager in JDSU's Communications Test and Measurement business segment. "To address this, JDSU's unique combination of both jitter and wander functions empower network equipment manufacturers and service providers with these capabilities for the first time over 10GbE Synchronous Ethernet networks."

Basic Ethernet lacks the synchronization features necessary to ensure reliable video and mobile backhaul networks. SyncE has emerged as a simple link-by-link replacement for SONET/SDH that retains backward compatibility, leverages the existing synchronization architecture, and cost-effectively enables current and next-generation services such as IP-based video services. SyncE, which is currently on the market for 1GE and 10GE and will be supported in future 40GE and 100GE networks, promises to deliver necessary timing functions and accelerate the transition from TDM to packet networks.

JDSU is also actively working in International Telecommunication Union Telecommunication (ITU-T) study groups to standardize different aspects of SyncE jitter and wander testing. JDSU says the ONT jitter module is compliant with the performance requirements for SyncE interfaces recently defined by ITU-T.

JDSU says its module can perform the three most common jitter measurements -- jitter generation, jitter tolerance, and jitter transfer -- with best-in-class, intrinsic jitter to get enough margin to the specified jitter tolerance limits required by ITU-T standards. These measurements help determine the amount of jitter acceptable at SyncE interfaces.

The JDSU jitter module supports the research and development, system verification, and production of component vendors and network equipment manufacturers, as well as the equipment verification, installation and maintenance requirements of service providers.
