Siemens Communications Inc. on Monday announced the United States introduction of its SURPASS hiT 7300 optical transport platform for regional and long-haul applications.
The new system is a “little brother” to the SURPASS hiT 7500, said Alan Gibbemeyer, director of Siemens’ next generation business unit networks division. It features 40 channels instead of the 80 on the 7500, and it reduces the initial build costs (capex and installation) by 80 percent, he said.
Siemens also has reduced the 7300’s need for on-site work and has automated system setup to a great degree. Configuration, monitoring and software updating are managed centrally. Gibbemeyer said the opex has been minimized in part by “flattening” the network, and automating across multiple network layers – from metro to regional to backbone, for example. This means the new client equipment can be deployed with just two truck rolls – at each end point. “You don’t have to mess with points in the middle,” he said.
Gibbemeyer added with these new metrics the 7300 extends Siemens’ optical technology to new markets. “The challenge for our customers is that bandwidth is growing tremendously,” he said. “They need optical/DWDM solutions. It’s not just the IXCs or major services providers; the need spans a greater target.”
SURPASS hiT 7300 includes the required features of an optical platform, including OADM, ROADM and photonic cross connect (PXC) options. Ethernet, SONET/SDH, SAN or OTH service interfaces are available to be remotely provisioned via software commands.
It supports a range of throughput capacity – from 2.5gbps to 3.2tbps – and topologies – from point-to-point to rings to meshed networks. Deployments can range from passive, unamplified 8-channel CWDM for smaller metro access applications, all the way up to active, amplified 80-channel DWDM applications for long-haul and ultra-long-haul.
“Siemens has enhanced its competitiveness with the SURPASS hiT 7300, addressing service operator requirements for scalability, flexibility in service interfaces, and reduced operating expenses for service provisioning,” said Dave Dunphy, research director of network infrastructure at Ovum-RHK. “The hiT 7300 also offers service providers a migration path to automatically switched optical networks, giving them a means to increase network reliability and address the increasingly dynamic service needs of end customers.”
