Solution Overview

Problem

Current optical transceiver modules for high-speed networks, such as 800 G-DR8, often require external splitter cables or fiber patch panels to break out bandwidth into individual optical channels, which reduces system integrity and increases costs.

Innovation Solution

A pluggable optical transceiver module design that integrates eight duplex fiber sockets directly into the module, eliminating the need for external connectors like MPO and allowing for eight individual optical channels without adapters, thereby reducing optical losses and back reflections and providing fiber length flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If external splitter cables or fiber patch panels are used to break out bandwidth into individual optical channels, then the optical system can be configured for multiple channels, but system integrity is reduced and cost increases

Engineering Contradiction:

Improveoptical channel configurationVSAvoidsystem integrity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent integrates eight duplex fiber sockets directly into the OSFP optical transceiver module, merging the function of external splitter cables and fiber patch panels into the module itself. This eliminates multiple connection points and reduces the number of components between the transceiver and optical fibers, thereby maintaining system integrity while providing versatile optical channel configuration.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If external splitter cables or fiber patch panels are used to break out bandwidth into individual optical channels, then the optical system can be configured for multiple channels, but cost increases

Engineering Contradiction:

Improveoptical channel configurationVSAvoidnetwork cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By integrating eight duplex fiber sockets directly into the OSFP module, the patent eliminates the need for separate external splitter cables and fiber patch panels. This integration reduces the total number of components required in the network deployment, lowering material costs and simplifying installation while maintaining the ability to configure multiple optical channels.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If external connectors like MPO are used, then multiple optical channels can be supported, but optical losses and back reflections increase

Engineering Contradiction:

Improveoptical channel supportVSAvoidoptical loss

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent extracts the fiber connection function from external connectors like MPO and integrates it directly into the OSFP module through eight built-in duplex fiber sockets. This eliminates the need for separate external connectors, reducing the number of connection interfaces and thereby minimizing optical losses and back reflections while maintaining support for multiple optical channels.

Inventive Principle:
