Solution Overview

Problem

Existing cable assemblies fail to provide proper cable pinouts and polarities for connecting new configurations of data center equipment capable of handling higher data transmission rates.

Innovation Solution

A cable assembly comprising a first end connector, multiple second end connectors, and a conversion cable to facilitate connections between a single high-speed transceiver and multiple lower-speed transceivers, utilizing specific fiber ferrule configurations and pin layouts to support 400G and 100G transmission rates.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If existing cable assemblies are used, then the connection structure is simple, but the cable pinouts and polarities do not support new data center equipment configurations for high data transmission rates

Engineering Contradiction:

Improvecable pinout compatibilityVSAvoidcable assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable assembly is divided into distinct functional segments: a first end connector with first fiber ferrules for high-speed transceivers, multiple second end connectors with second fiber ferrules for lower-speed transceivers, and conversion cables with specific pinout configurations. This segmentation allows each component to be optimized for its specific function while maintaining overall system versatility for different data transmission rate configurations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cable assembly is designed to support multiple transmission rate configurations (400G and 100G) through its multi-functional connector design. The first end connector can interface with high-speed transceivers while the multiple second end connectors can interface with lower-speed transceivers, allowing the same cable assembly to serve different data center equipment configurations without requiring separate specialized cables for each scenario.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a cable assembly supports multiple transceiver configurations, then adaptability improves, but manufacturing complexity increases

Engineering Contradiction:

Improvetransceiver configuration supportVSAvoidcable assembly fabrication

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Different sections of the cable assembly have specialized local characteristics: the first end connector uses first fiber ferrules optimized for high-speed transceiver connections, while the second end connectors use second fiber ferrules optimized for lower-speed transceivers. The conversion cables have specific pinout configurations tailored to their local function. This localized optimization simplifies manufacturing by allowing each section to be produced using standard processes for its specific application rather than requiring complex custom fabrication for the entire assembly.
