NETWORK OPERATOR Tata Communications has lit up a 100Gbit/s link between London and New York, promising lower latency between the two locations.

Tata Communications, which operates one of the largest IP networks around, announced that it has upgraded the TGN-A undersea cable between London and New York. The firm said the new cable with a bandwidth of 100Gbit/s will not only lower the latency between the two points of presence (POPs) but provide higher uptime.

Traditionally Tata and other network operators have used POPs in New York and London as landing points for trans-Atlantic cables, though in recent years there has been some diversification. Since the two locations are large cities and perhaps more importantly have large financial districts, the demand for high-bandwidth, low-latency connectivity remains high.

Genius Wong, SVP of Global Network Services at Tata Communications said, "The move to 100G coherent technology on our TGN-Atlantic cable system demonstrates our leadership in global network infrastructure. Based on Ciena's Geomesh, this major deployment will bring maximum bandwidth, lower latencies, higher uptimes and seamless scalability for carriers and enterprises, today and in the future."

To put Tata's 100Gbit/s link into perspective, most datacenters rely on 10Gbit/s connections for their internal LAN, while high performance computing clusters making use of Infiniband interconnect top out at 40Gbit/s and operate at much shorter distances. Tata said that the upgrade of the London to New York link to 100Gbit/s is the first in its network and that it will upgrade other parts of its 210,000km fibre network in the future. µ
