Anritsu and Fujikura work on Raman
amplifiers
Anritsu and Fujikura are to collaborate on the development of Raman optical amplifier systems for applications in 10 and 40Gbit/s long-haul and ultra-long-haul DWDM optical transmission systems.
Anritsu and Fujikura are to collaborate on the development of Raman optical amplifier systems for applications in 10 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 high power 14XXnm pumping lasers from its Tanasawa factory in Japan

New option provides the world first suite of GCF-approved RF/RRM tests of MBMS functions for test and validation of HSPA mobile terminals.
Anritsu is one of only a few suppliers capable of volume manufacture of 14XXnm pumping lasers offering 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.
Projected worldwide sales are around GBP 2.5 million for the 2002 financial year, increasing to GBP 17 million in 2005.
