Synchronization Equipment for Power Distribution Network
Telecommunication networks are an essential infrastructure for the operation of any power distribution network. The telecommunication services used by power companies can be divided into two classes. First there are the services corresponding to the general communication needs such as telephone services and general data communication services for the operation of the enterprise computer network. Secondly there are special communication needs related to the operation of the physical power distribution network.
Synchronization network is based on SDH or SONET transmission technology. SDH and SONET transmission networks are TDM networks, hence they require synchronization. At the same time the SDH links can be used to transport synchronization.
A PRC generates an accurate and stable reference synchronization signal. Primary Reference Clocks are usually realized with atomic Caesium clocks or with GNSS-receivers, or with a combination of both. The output signal of the PRC drives a so-called SSU or BITS clock. The SSU/BITS acts as a node clock and supplies all telecom equipment of the node or building with adequate synchronization signals. For the transmission of synchronization over long distances, SDH transmission signals are used as carriers.
The physical data rate of the SDH data signal, being driven by the SDH multiplexer’s synchronized equipment clock, conveys synchronization which is derived from the PRC. At the receiveing end, an SSU/BITS eliminates synchronization degradations such as jitter and wander and distributes clean synchronization signals to teleom equipment in the node or building.
OSA 5405 Series
For maximum benefits, small cells need tight synchronization. With our OSA 5405 SyncReachTM, this is easier than ever before. It features a unique dual antenna that enables it to deliver accurate and affordable small cell synchronization even in urban canyons.
A clear sky view is no longer essential for accurate and reliable GNSS-based synchronization. Our OSA 5405 can be deployed in deep urban canyons closer to where small cells are located. This avoids the archaic and expensive RF cable feeds of typical GNSS installations. Instead, the OSA 5405 uses costeffective Ethernet cabling and offers both electrical and optical interfaces. Our OSA 5405 comes in two variants:
- the OSA 5405-O for outdoor installations on a wall or a pole;
- and the OSA 5405-I for indoor
installations at windows or interior walls. Indoor- or outdoor-mounted, even at street level in deep urban canyons, our OSA 5405 offers unprecedented flexibility. And, with its dual GNSS receivers and PTP grandmaster, it delivers the accurate timing that small cells require.
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.
SyncView Plus
SyncView™Plus is a comprehensive synchronization Management System that allows telecom operators to manage all Oscilloquartz synchronization elements from a single local RS-232 serial connection to one shelf up to hundreds of units from a single point via remote Ethernet connection.
