Nokia Siemens Networks deploys Mintera’s Adaptive-DPSK 40Gb/s DWDM module

Mintera Corp of Acton, MA, USA, which makes high-bit-rate optical transport sub-systems, says that Nokia Siemens Network’s updated hiT 7300 transport product now incorporates its MI 4000XM Adaptive-DPSK module, which is in full deployment supporting 40Gb/s services.

“It is a very reliable component, enabling simple upgrading of high-capacity DWDM [dense wavelength division multiplexing] systems to 40Gb/s line speed,” says Uwe Fischer, head of Nokia Siemens Networks’ DWDM business line, of the Mintera module.

“Mintera greatly values the opportunity of working with Nokia Siemens Networks as a lead customer,” says the module supplier’s president & CEO Terry Unter. “The commercial deployment of our combined products demonstrates the strength of performance and quality of Mintera's MI 4000XM.” Adaptive-DPSK provides the most cost-effective, longest-reach solution suitable for the majority of 40Gb/s applications worldwide, he claims.

“This is just the first of many 40Gb/s network deployments for the hiT 7300 using Mintera’s MI 4000XM, with substantial Adaptive-DPSK deployment volumes expected for the next several years,” Fischer continues.

The patent-pending Adaptive-DPSK technology incorporated in the MI 4000XM DWDM module enables 40Gb/s transport on 50GHz channel-spaced systems and transmission over agile reconfigurable optical add-drop multiplexer (ROADM) networks without compromising critical ultra-long-haul (ULH) reach. The unit conforms to the industry-standard footprint and incorporates an electrical mux/demux for compatibility with any 40Gb/s framer. The module has a 300-pin MSA connector with support for the appropriate I2C commands, enabling simple hardware and software integration.
