Start with the news release Spectrum analyser with high wavelength range from Yokogawa - Test and Measurement, which we summarised at the time by saying "The AQ6370C from Yokogawa combines accuracy and resolution with ultra-high dynamic range, comprehensive interfacing and ease of use.". Several months prior to that, we featured the news release Bridge100 develops optical data communication from Achronix Semiconductor: "FPGA specialist Achronix Semiconductor and optical module supplier Opticomp have launched a platform for developing, characterising, and demonstrating high-speed optical data communication.".
 
In December 2009, we covered the news from Gao FiberOptics - take a look at GAO rolls out single-mode-to-multimode converter which says: "GAO Fiber Optics has rolled out a single-mode-to-multimode (SM-to-MM) converter operating in full-duplex mode.".
 
Take a look also at the news release from Neophotonics, Options added to XFP pluggable transceiver line, as well as Trend announces Fibre Identifier from Trend Communications, and Trend develops optical light sources from Trend Communications.
