Electromagnetic Transmission TRIZ Cases
- Frequency Synthesis Optical Frequency Domain Reflectometry
Frequency synthesis-based optical frequency domain reflectometry suppresses phase noise to extend detection distance beyond coherence limits.
- Optical Fiber Health Analysis Using Historical Data
Logs historical metrics to detect degrading connections before failures occur.
- Raman Pump Laser Switching via NRZ Signal Spectral Analysis
NRZ-coded service signal processing concentrates energy on the clock spectral line for reliable Raman pump laser switching.
- PAM-4 Data Transmission Device Using Toggle Serializer for Amplitude Modulation
Toggle serializer detects MSB and LSB transitions to drive amplitude modulation, reducing power consumption and chip area in high-speed data transmission.
- Optical Fiber Transient Event Logging via Timestamped Signal Sampling
Timestamped sampling of optical signal parameters correlates transient span loss events with other monitored system data to identify root causes of faults.
