SDH/PDH

Synchronization clocks for SDH networks

SDH is not only means of distributing frequency synchronization (just like SyncE), SDH requires frequency synchronization in order to work (unlike SyncE). Wander is induced by pointer activity. PDH tributaries need not be synchronous with the SDH aggregates (pointer technique), however, excessive relative wander between the incoming PDH tributary and the SDH aggregates induce wander on the outgoing PDH tributary (pointer adjustments!). This tributary wander causes slips in the E1 layer.The slip-rate affects the Quality-of-Service (QoS) perceived by the end-customer! Slip-rate objectives (G.822) and consideration on network structure led to the specification of a synchronization accuracy (fractional frequency) of 1E-11.

OSA 5410 Series

Our OSA 5410 Series is a family of compact and cost-effective synchronization distribution and assurance devices that brings the power of Syncjack™ to any access network. The OSA 5410 Series offers unique flexibility by supporting delivery and assurance of synchronization utilizing Synchronous Ethernet and IEEE 1588v2 Precision Time Protocol (PTP). Thanks to its built-in Global Navigation Satellite System (GNSS) receiver and Grandmaster (GM) Clock capability, it can be used as a timing source for frequency, phase and time-of-day delivery, as well as a measurement reference for Syncjack™ tools.
