Drive electo-optic modulators with FPGA

Depending on how much current the modulator requires, one solution might be a current feedback op amp. There are a number of high slew rate op amps with slew rates just about where you want it. One …

What options do I have to combine and format 18 600Mbps ADC serial streams over QSFP+?

Presuming you really do mean 600 Mbps and not 600 Msps times some number of bits, 18 x 600 Mbps = 10.8 Gbps. 10G Ethernet is 10 Gbps, so it would probably be doable without any compression if you run …

Using QSFP28 Module at Lower Lane Rate

If you aren't running at a compatible line rate, you'll need to disable the transceiver CDR circuitry. I have had to do this before when running at rates other than 25G, including at 10G. This can be …

What is used to detect light from fiber optic signals in high speed Internet?

Yep, high speed photodiodes are the simplest way to do this. A receiver will usually consist of a photodiode and transimpedance amplifier (current in, voltage out). After that, it's just a high speed …
