Sumitomo Electric Develops Coaxial Laser Diode Module for Base Stations

Sumitomo Electric Industries has developed a new coaxial laser diode module capable of supporting high frequency bandwidth applications.




Sumitomo Electric said that with the addition of the newly-designed model, its family of coaxial laser diode modules will be capable of supporting a broader frequency range, from 2GHz to 5GHz. The modules are used in mobile base station systems.


WiMAX supports three frequency bands (2.5GHz, 3.5GHz and 5.8GHz), as is defined in the IEEE 802.16-2004 specifications. The new coaxial laser module can support both the 3.5GHz and 5.8GHz bands.


One of the key features of the new module is its capability to achieve a 5GHz bandwidth. The new coaxial laser diode module will be available for sampling in Q3 2008 and for sale by the end of CY2008.http://www.sei.co.jp/index.en.html
