  /  The complexity of hyperspeed transceivers

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 they 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 about all 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…
As a small „one more thing” Thomas will dive into the basics of how FEC
compensates for errors caused by PAM4 modulation.
