SYSTEM, APPARATUS, AND METHOD OF LINK TRAINING OVER A REDRIVER-BASED OPTICAL INTERCONNECT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240345345 titled 'SYSTEM, APPARATUS, AND METHOD OF LINK TRAINING OVER A REDRIVER-BASED OPTICAL INTERCONNECT

Simplified Explanation: The patent application describes an electronic system with interconnect circuitry and a physical layer controller that accesses optical-capability registers to identify optical-training control information and optical-capability information. This information is used to initiate an optical-based link training procedure over a redriver-based optical interconnect.

• The electronic system includes interconnect circuitry for communication.
• The physical layer controller accesses optical-capability registers.
• Optical-training control information, such as a start-training bit, is identified.
• If the start-training bit is set to a predefined value, the controller initiates an optical-based link training procedure.
• The link training procedure trains a link between the electronic system and a partner system over an optical interconnect.
• The procedure is based on the optical-capability information.

Key Features and Innovation: - Utilization of optical-capability registers for link training control. - Initiation of an optical-based link training procedure based on specific control information. - Training of a link between electronic systems over a redriver-based optical interconnect.

Potential Applications: - Data centers - Telecommunications networks - High-speed communication systems

Problems Solved: - Efficient link training between electronic systems. - Optimization of optical-based communication.

Benefits: - Improved data transfer speeds. - Enhanced reliability in link training procedures. - Streamlined communication between electronic systems.

Commercial Applications: Optical-based link training technology can be utilized in data centers, telecommunications networks, and other high-speed communication systems to enhance data transfer speeds and reliability.

Original Abstract Submitted

for example, an electronic system may include interconnect circuitry to communicate over an electrical interconnect; and a physical layer (phy) controller configured to access a plurality of optical-capability registers to identify optical-training control information and optical-capability information. for example, the optical-training control information may include a start-training bit. for example, based on a determination that the start-training bit is set to a predefined value, the phy controller may initiate an optical-based link training procedure via the electrical interconnect to train a link between the electronic system and a partner electronic system over a redriver-based optical interconnect. for example, the optical-based link training procedure may be based on the optical-capability information.
