Optical interconnect

Optical interconnect

Optical interconnect is a way of communication by optical cables.[1] Compared to traditional cables, optical wires are capable of a much higher bandwidth, from 10 Gb/s up to 100 Gb/s.[2]

The technology is currently being introduced as a way to link computers to mobile devices,[3] as well as on motherboards and devices within computers [2][4]

IBM has created a prototype optical interconnect using wavelength-division multiplexing (WDM). They suggest that if successful, this technology could lead to the first computer capable of exascale computing (a computer that can perform a billion billion computations per second).[5] A waveguide emits eight different colored beams into several different ports of a modulator, which allows eight signals to be transferred concurrently. This multi-wavelength beam travels through the chip, with optical switches controlling the direction.[6]
