ADVA Introduces Synchronous Ethernet Access for Mobile Backhaul

ADVA Optical Networking introduced an demarcation device that enables Ethernet and synchronization to be delivered over fiber-based Ethernet transport.

The ADVA FSP 150CC-GE206 is designed for service providers looking to deploy an Ethernet service optimized for mobile backhaul applications. It enables synchronous Ethernet (SyncE) to replace traditional T1/E1-based synchronization in the delivery of Ethernet services. Additionally, the service intelligence of the latest Operations, Administration and Maintenance (OAM) standards such as 802.1ag, Y.1731 and RFC 2544 are all critical to guaranteeing that mobile Service Level Agreements (SLAs) are met.

Circuit emulation is used to enable standard T1/Ei service delivery over a pure Ethernet network. In addition, ADVA notes that network-based synchronization of radio equipment allows wireless operators to save the expense of external reference clocks. Sync-E also enables extremely accurate delay/jitter SLA measurement, surpassing requirements imposed by wireless operators on access vendors. Optional Wide Area Network (WAN) protection, redundant power supplies and temperature hardening ensure high service availability. An in-service SLA monitoring capability is also supported.

'With recent advances in synchronous Ethernet ('SyncE') standards, the Ethernet protocol can now support mobile base station synchronization needs, and is also backwards compatible with 2G and 3G services,' explained Christoph Glingener, chief technology officer at ADVA Optical Networking. 'This new product expands our Ethernet access family of products in a way that supports the cost-effective delivery of new Ethernet services.'

The ADVA FSP 150CC-GE206 is currently in operator tests.
