Siemens ICN intros new transponder card

GERMANY -- Siemens IC Networks (ICN) has introduced a new transponder card for optical data transmission employing tunable laser. It allows selection and transmission of one of the 80 tunable wavelengths. Up until now, the practice has been to use cards with fixed wavelengths. Using the novel solution will give carriers a clear advantage in terms of cost of operations and spare parts inventory management. It will also enable carriers to offer their customers additional services on other wavelengths.

The new transponder card is part of the SURPASS hiT 75xx-er series for next-generation optics. A DWDM system with modular and scalable architecture, it can be deployed in applications ranging from regional to ultra-long haul. A single tunable transponder can cover 80 different channels for network expansion and repair replacements, reducing carrier's inventory costs.

Siemens has also expanded the Surpass hiT 75xx-er series to provide a new optical add-drop multiplexer (OADM). It can add or drop up to 100 percent of the transmitted wavelengths on an all-optical basis. It eliminates costly electrical regeneration and facilitates flexible traffic planning. The integrated automatic analysis and control of optical signals in the DWDM network area also allows additional channels to be added on a plug-and-play basis, providing a further reduction in operating costs.
