Here’s how it works, step by step:
The transmitter chip is made of four hybrid silicon lasers.
Light beams from the lasers each travel into an optical modulator.
The modulator encodes data onto the beams at 12.5Gbps.
The four beams are then combined and output to a single optical fiber, for a total data rate of 50Gbps.
At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors.
The photo detectors convert data back into electrical signals.
