Optical interconnect architectures

Definition

Optical interconnect architectures refer to the design frameworks that utilize optical fibers and photonic devices to transmit data at high speeds over short or long distances. These architectures are integral to enhancing bandwidth, reducing latency, and improving energy efficiency in data centers and communication networks. By integrating optoelectronic components like lasers, photodetectors, and modulators, these systems can effectively replace traditional electrical interconnects with advanced optical solutions.
