Anritsu and Fujikura to jointly develop new Raman amplifier
9 August 2002 -- Anritsu and Fujikura are to collaborate on the development of Raman optical amplifier systems for applications in 10Gbit/s and 40Gbit/s Long-Haul and Ultra-Long-Haul dense wavelength division multiplex (DWDM) optical transmission systems.
Fujikura will design and develop the Raman Amplifier using its comprehensive range of fibre and passive components, while Anritsu will supply the 14XXnm pumping lasers from its Tanasawa factory in Japan. These pumping lasers offer output powers greater than 300mW.
Multi-laser diode Raman optical sources are created by combining several fibre Bragg grating stabilised pumping lasers, typically using four or five wavelengths between 1400 and 1500nm. The distribution of the pumping wavelengths is critical in achieving a flattened gain response for C- and L-Band optical amplification.
Initial development plans will allow Fujikura to introduce early customer samples from August 2002. Anritsu expects that projected worldwide sales willl be around EUR2.5m for the 2002 financial year, increasing to EUR17m in 2005.
