?Dwdm?

An Electronicstalk guide

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 Reflective SOA-EAM for DWDM networks from CIP Technologies: "CIP Technologies has launched the R-SOA-EAM-1550 - a device that integrates a semiconductor optical amplifier with a reflective electro-absorption modulator - at the ECOC 2009 conference in Vienna.".

In September 2009, we covered the news from Neophotonics - take a look at Neophotonics launches MEMS-based VOAs which says: "Neophotonics has announced the addition of the FVOA8000 and FVOA8100 variable optical attenuators (VOAs) to its range of MEMS-based VOAs.".

Take a look also at the news release from Neophotonics, Options added to XFP pluggable transceiver line, as well as Neophotonics introduces passive PIC-based products from NeoPhotonics, and Infinera demonstrates PIC-based DTN system from Infinera.
