Synchronous Ethernet Standards Will Enable Metro Ethernet Growth

By Rich Steeves, TMCnet Web Editor

We have all heard about how the rapid adoption of mobile devices such as smartphones and tablets and the looming adoption of 4G and LTW services will affect a broad range of communications and technology sectors. This drastic increase in traffic stands to impact metro Ethernet networks quite a bit, but fortunately, a new standard for distribution of frequency over Ethernet links is poised to make a big impact on the metro Ethernet space.

Synchronous Ethernet (SyncE) will provide PHY-level frequency distribution through an Ethernet port. It will help mobile networks achieve accurate and stable frequency reference.

SyncE will use external timing technology to provide this information, but unlike previous technology, it does not reply on Cesium oscillators or GPS technology as a clock source.

Since Ethernet is still the most common way that remote areas are connected to hubs, this new standard will greatly impact many mobile networks. Therefore, it will have quite an impact on metro Ethernet networks, as experts expect major growth in the metro Ethernet space as IP voice and mobile technologies grow exponentially.

As more and more traffic is transferred to metro Ethernet networks, the SyncE standards can provide robust protection for frequency accuracy and stability. In fact, in regards to backhaul, where an Ethernet network interfaces with a TDM network, SyncE can provide the necessary clocking input for next-gen Ethernet-based base stations.

“It is important that we focus on resources and technology to enhance service provision within the mobile and telecommunications space. Infrastructure is critical to the development of businesses and this is helping to drive the domestic market,” said Paule Luff, country manager Edge-Core Networks South Africa, as reported in a blog post by Isaac Twumasi Quantus that appeared on “The relevance of Synchronous Ethernet is such that we have an offering that transforms the inner core of what constitutes connectivity and online traffic management. This can only bode well for the sustainability and efficiency of connectivity and communication.”

In other industry news, recently metro Ethernet specialist FiberLight (News - Alert) was awarded a contract to build over 40 new towers in the Tampa, Fla., area.
