Symmetricom, Inc., has introduced new RoHS compliant versions of its existing SyncServer S200 and SyncServer S250 GPS Network Time Servers. Designed for large or expanding IT enterprises, the cost-effective SyncServer S200 and S250 with optional rubidium-based atomic clocks will reliably continue operational service for extended periods when primary time sources are impaired.
Accurate network time-keeping is essential for modern data networks to support a number of key functions — including precision time stamping, scheduled data backups, network management and security. These functions all rely on networked clocks to stay synchronized with each other. By using enterprise owned servers, companies are better poised to ensure accurate, reliable and more simplified network timing and synchronization, Symmetricom said.
The European Union’s Restriction of Hazardous Substances directive (or RoHS) assures environmental responsibility for the materials used in electrical and electronic equipment. The SyncServer S200 and S250 now offer network managers and engineers RoHS certified, entry-level time servers that still allow them to take advantage of rubidium-based clock technology. Unlike the more commonly deployed time servers that leverage temperature-compensated crystal oscillator (TCXO) and oven-controlled crystal oscillator (OCXO) technologies, the rubidium-based SyncServers provide superior holdover — technology that allows the network to continue to operate with accurate timing when the primary reference (usually GPS) is temporarily impaired due to events such as GPS jamming, antenna breakage, or solar interferences.
Communications and information technology managers can now take control of their network timing and synchronization and be assured of very accurate timing in their network that will not degrade or disrupt services during long periods where holdover is necessary, Symmetricom said.
