Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical transceivers face challenges in providing stable diagnostic information due to noise from electrical, thermal, and mechanical sources, leading to inconsistent measurements of operational parameters like temperature, voltage, and power.
Innovation Solution
An optical transceiver equipped with a system memory and processor that performs filtering on digital samples of operational parameters using microcode, employing techniques such as averaging, Infinite Impulse Response (IIR), or Finite Impulse Response (FIR) filtering, to provide stable and accurate diagnostic data before reporting it to a host computing system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If digital diagnostics information is reported directly from sensors to host without filtering, then the host receives raw operational parameter values, but the values are unstable and inconsistent due to electrical, thermal, and mechanical noise
Solution Approach 1:
The patent applies preliminary action by performing filtering operations on digital diagnostics information before it is reported to the host computing system. The optical transceiver collects multiple samples of operational parameters and applies filtering algorithms (such as averaging, IIR, or FIR filtering) to these samples prior to reporting, thereby eliminating noise and instability from the source rather than requiring post-processing at the host end.
2Reliability
If filtering is performed on digital samples within the optical transceiver, then the stability and accuracy of diagnostic information is improved, but additional processing requirements are imposed on the transceiver
Solution Approach 1:
The patent implements self-service by enabling the optical transceiver to autonomously perform filtering operations on its own diagnostic data using embedded processing capabilities. The transceiver collects samples, applies filtering algorithms, and generates stable diagnostic information independently, without requiring external assistance or additional complex processing hardware beyond what is already integrated in the transceiver's controller.
3Measurement precision
If multiple digital samples are collected for filtering, then the filtering accuracy is improved, but the time required to obtain stable diagnostic values increases
Solution Approach 1:
The patent applies periodic action by collecting multiple samples of operational parameters at regular intervals and applying filtering operations to this time-series data. The systematic periodic sampling allows the filtering algorithm to effectively average out noise and extract stable diagnostic values, achieving high accuracy without requiring excessively long measurement periods.
Data Source
AI summary
An optical transceiver configured to perform filtering of digital diagnostics prior to the filtered results being made accessible to a host computing system (hereinafter referred to simply as a “host”) that is communicatively coupled to the optical transceiver. The optical transceiver includes sensor(s) that measures analog operational parameter signals such as temperature and supply voltage. The analog signals are each converted to a plurality of digital samples by analog to digital converter(s). A processor executes microcode that causes the optical transceiver to perform filtering on the various samples. The optical transceiver may then make the filtered result accessible to the host.
