1. Market Trends
The daily and rapid spread of the broadband environment is lead by FTTx. In these circumstances, core networks are starting to see a genuine transition from 100 Gbps. In particular, the focus is on traffic between Internet Exchanges (IXx) and Internet Service Providers (ISPs) and the data rate at the Japan IX (JPIX) now exceeds 100 Gbps, while the work’s busiest IX in Amsterdam (AMSIX) exceeds 400 Gbps.
The resolve these types of bottlenecks in core networks, in July 2006, the IEEE started work on examining the 100GbE standard under the auspices of the HSSG (High Speed Study Group); work started in November 2007 on the IEEE802.3ba standard with the aim of implementation in June 2010. The group is investigating a 100 GbE standard for connecting IXs, ISPs, and Content Service Providers (CSPs) as well as a 40GbEstandard for connecting servers, etc, in data centers. However, these discussions are not just about standards for LANs using 100 and 40 GbE, but also cover OTN (Optical Transport Unit: OTU3, OTU4) IT-T SG15 standards for WANs supporting long haul transmissions. R&S into and rollout of 40 gbps, long haul transmission systems, especially undersea cables, using previously commercialized SDH/SONET/OTN transmission technologies is already starting.
In addition to explaining the latest technology trends from the viewpoint of a measuring instrument maker, this article also describes the important measurement items.
