Siemens Introduces 80-Channel, Tunable Laser Card

Siemens IC Networks introduced a tunable laser card for its DWDM platform aimed at regional to ultra-long haul networks. The new card supports 80 channels and could be used for network expansion projects or for sparing. Apart from the new transponder card, Siemens has expanded its optical portfolio to include a new type of optical add-drop multiplexer that allows up to 100% of the transmitted wavelengths to be added and dropped on an all-optical basis. The design eliminates costly electrical regeneration and also 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.
