We see from your search that you're looking for information on the term "Optical transmission",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release Network tester runs up to 43Gbit/s from
Exfo Electro-Optical Engineering, which we summarised at the time by saying "Module provides advanced Sonet/SDH and OTN test functions in a single module to address the demands of commissioning and troubleshooting 43Gbit/s networks".
Earlier in the week,
we featured the news release Optical transmission via distribution from
Focus EDL: "Franchise gives Focus EDL access to an extensive range of optical products designed for applications that require high-datarate networking".
In July 2007, we covered the news from TTTech Computertechnik
concerning its TTX-Optical Link
- take a look at Link checks FlexRay for EMC
which says: "The TTX-Optical Link is a compact device for electrical decoupling of FlexRay bus signals for EMC testing".
Take a look also at the news release from Photonic Products, Laser modules gain Germanic distribution,
as well as Laser promises isolator-free optical transmission from Oki Electric,
and Tunable laser supports 40Gbit/s DWDM traffic from Bookham.
