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.
OSA 5420 Series
Our OSA 5420 series is a family of cost-effective, mid-scale synchronization distribution and assurance devices that bring the power of Syncjack™ to any network. Following a toolbox approach, the family members of the OSA 5420 series can be utilized in a variety of network synchronization applications, including IEEE 1588v2 Grandmaster, Boundary Clock, Slave Clock and Assisted Partial Timing Support (APTS).
OSA 5430 Series
With our OSA 5430, a carrier-grade IEEE 1588v2 grandmaster clock supporting 10Gbit/s as well as 1Gbit/s interfaces with hardware timestamping, cost-effective and accurate synchronization distribution for next-generation technologies such as LTE-A is no longer a challenge. What’s more, its NTP server, multiple BITS outputs and GNSS receiver capabilities, make it also ideal for the smooth upgrade of legacy synchronization architectures.
OSA 5548C SSU
Our OSA 5548C Synchronization Supply Unit is a scalable synchronization solution rangingfrom 20 unprotected outputs up to 1,000 protected outputs by adding up to four expansion shelves to the core unit. Its ultra-compact footprint makes it ideal for telecom operators to provide scalable network synchronization in over-crowded exchanges.
