Pipe Networks to upgrade Sydney Guam cable to 100Gbps

TPG subsidiary, Pipe Networks, is to upgrade its PPC-1 Sydney-Guam 
submarine cable to 100gbps per wavelength operation using Infinera's DTN-
X platform, increasing capacity on the cable to more than 3Tbps.

The Infinera DTN-X platform has also been selected for the company's 
terrestrial network connecting several data centres in Sydney, enabling a 
single fibre to carry up to 8Tbps.

Infinera says that Pipe selected its technology "After a detailed multi-
vendor evaluation process..for the scalability, efficiency and simplicity 
it brings to its network."

Lee Harper, head of network engineering for Pipe Networks and the TPG 
Group, said: "The DTN-X platform's interoperability between our existing 
terrestrial and submarine networks, its ease of use when provisioning 
services along with the elimination of transponders at cable landing 
stations all led to our decision. We move a significant amount of data 
around the country, and deploying the DTN-X allows us to distribute 
reliable, high-capacity services with great simplicity and with industry-
leading provisioning lead times."

According to Infinera "One of the key factors in Pipe's selection of the 
Infinera DTN-X platform was the attraction of a solution based on 
photonic integrated circuits (PICs)."

"Additional key benefits of the Infinera DTN-X platform include: PICs 
enable high capacity wavelength division multiplexing to be integrated 
with 5Tbps of Optical transport network (OTN) switching without 
performance compromise; integrated non-blocking OTN switching allows each 
wavelength to be efficiently utilised, resulting in fewer wavelengths for 
a set of service demands; a reduction in capital and operating costs due 
to fewer fibre connections, less space and lower power consumption across 
the network, resulting in more cost effective services for Pipe's 
customers."

PPC-1 went live in October 2009. It comprises two fibre pairs each with 
10Gbps wavelengths and capable of carrying 2.56Tbps (128 × 10Gbps 
wavelengths per fibre pair). 

According to the Pipe Networks' web site, "A move to 40Gbps wavelengths 
would boost the system capacity to 7.68Tbps with no changes other than 
new hardware in the cable stations. A small reconfiguration of the 
network and capacity could be taken as high as 10.24Tbps."
