Compact 40Gbps optical platform drives top performance at lower OPEX

30 марта 2009

Nokia Siemens Networks has created the most compact (seven modules per sub-rack) and cost-efficient 40Gbps platform in the industry. In addition, the new design increases flexibility to support more revenue generating services. The enhancements come with release 4.25 of the company’s hiT 7300 optical platform.

The new platform is the company’s response to a continuing need to drive greater network efficiency as data traffic grows exponentially and revenues-per-bit decline. It simplifies networks, reducing network elements, rental space and power consumption while increasing reliability, which results in lower operating costs.


As well as targeting savings for carriers, the new hiT 7300 can help generate revenue. The platform is ideal for applications such as high definition video on demand and IPTV allowing operators to expand their services. In release 4.25, this flexibility is accomplished by a single blade Add-Drop Multiplexers (ADM). This ADM card supports standard point-to-connections, along with all topologies needed for broadcasts and multicasts and all common aggregation applications, such as mobile backhaul.


In response to customer demand, the hiT 7300 was the industry’s first DWDM platform to serve both metro and core needs. The new 4.25 release delivers further technical enhancements operators have demanded, in particular maximizing the utilization of existing fiber in their networks. The hiT 7300 offers an optional (Polarization-Mode-Dispersion-Compensator (PMDC)) which helps older, lower-quality or stressed fibers achieve up to three times their current reach. The end result is a platform that meets operator requirements in terms of bandwidth, reach (up to 1600 kilometers) and the protection of past investments in fiber. Due to its small size, the platform requires no additional transponder shelf.


“The upgrades we’ve made to the hiT 7300 are a response to what we hear from customers every day – and we’ve already seen strong pre-release demand for the latest product,” said Uwe Fischer, Nokia Siemens Networks’ DWDM business line. “By further developing the hiT7300 we’re helping operators where it matters most, reducing cost for spares, operation and maintenance, training, network management, space and power consumption, while increasing flexibility in the network.”


International carrier have already performed lab tests with the hiT 7300 4.25. “We were happy to see that they found the benefits they were looking for,” Fischer said.
