Solution Overview
Problem
Existing MSA-compliant optical transceivers lack support for wavelength tuning, which is necessary for advanced applications like CWDM and DWDM, and do not provide compatibility with host devices that do not natively support wavelength tuning diagnostics.
Innovation Solution
A method and apparatus for conveying wavelength tuning information from a pluggable optical transceiver to a host device by determining the wavelength tuning information and appending it to existing data communicated between the transceiver and the host device, using existing MSA diagnostic information, such as the vendor part number field, to enable wavelength tuning in MSA-compliant transceivers that do not natively support this feature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If MSA specifications tightly define mechanical, electrical, and optical characteristics to maximize density and minimize cost, then manufacturing complexity is reduced and interoperability is improved, but wavelength tuning capability is lost and advanced optical performance is limited
Solution Approach 1:
The patent implements wavelength tuning capability in MSA-compliant transceivers by making the optical characteristics dynamic rather than fixed. The transceiver can adjust its operating wavelength within the defined MSA parameters, allowing it to adapt to different wavelength requirements (CWDM, DWDM, WDM applications) while maintaining compliance with the standardized mechanical, electrical, and thermal specifications. This dynamic adjustment resolves the contradiction by preserving manufacturing simplicity while enabling wavelength versatility.
Solution Approach 2:
The patent changes the optical parameters of the transceiver to enable wavelength tuning. By modifying the optical characteristics (specifically the transmission wavelength) while keeping other MSA-defined parameters constant, the transceiver achieves advanced optical performance and wavelength adaptability without requiring changes to the standardized mechanical, electrical, or thermal specifications, thus maintaining ease of manufacture and interoperability.
2Reliability
If existing MSA-compliant optical transceivers are used without wavelength tuning support, then host device compatibility is maintained, but support for advanced applications like CWDM and DWDM is lost
Solution Approach 1:
The patent enables dynamic wavelength adjustment in MSA-compliant transceivers, allowing them to adapt to different application requirements (CWDM, DWDM, WDM) while maintaining compatibility with existing host devices. The transceiver dynamically tunes its operating wavelength within the standardized optical parameters defined by MSA, ensuring that host device interoperability is preserved while enabling support for advanced optical applications.
Solution Approach 2:
The patent makes the MSA-compliant transceiver universal by enabling it to perform multiple functions across different wavelength requirements. A single transceiver design can now support various applications (CWDM, DWDM, WDM, and standard applications) by tuning its wavelength, eliminating the need for separate transceiver types for different wavelength needs while maintaining host device compatibility through adherence to standardized interfaces and protocols.
3Productivity
If wavelength specific decisions are removed from manufacturing to streamline production, then manufacturing efficiency is improved and inventory control is simplified, but wavelength tuning functionality cannot be implemented
Solution Approach 1:
The patent implements dynamic wavelength tuning capability in a standardized MSA-compliant transceiver platform, allowing a single manufacturing process to produce transceivers that can be configured for different wavelengths through software or control mechanisms rather than hardware variations. This maintains manufacturing efficiency and streamlined production while enabling wavelength tuning functionality, as the physical platform remains standardized but its optical operating point can be dynamically adjusted.
Solution Approach 2:
The patent creates a universal transceiver platform that can serve multiple wavelength requirements through a single standardized design. By removing wavelength-specific hardware variations from the manufacturing process and implementing wavelength selection through control mechanisms, the system achieves both manufacturing efficiency (streamlined production of standardized units) and wavelength tuning functionality (ability to configure for different wavelengths post-manufacturing).
