Thomas will describe in detail the structures inside optical transceivers. A Transmitter / Receiver Optical Sub Assembly (TOSA / ROSA) is no longer just a diode in a housing handling the light path to and fro to the fiber.
The performance increases from 10G to 100G onwards to 400G – are not only giant steps in bandwidth there are matching leaps in manufacturing.
How did the optical industry players around the globe make it possible to squeeze everything into the tiny form factors we see today? It is all about precision – a microscope with a calm and competent hand is no longer sufficient, now it is about; nano tolerances, testing, complex transceiver firmware and a shed load of money.
This is the high precision optical mechanical engineering revolution which fuels the hyper growth of data centers and optical networking worldwide…
If you face design issues with your current optical network design Thomas will give insights into the latest 40G to 400G transceiver developments (e.g. long distance 80km) which you can expect to see in the upcoming months. Hopefully this might save you some headaches.
As a small „one more thing”” Thomas will dive into the basics of how FEC compensates for errors caused by PAM4 modulation.
