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.
