Wavelength-Division Multiplex Systems TRIZ Cases
- DWDM Flex-Grid Channel Shifting for Spectrum Gap Utilization
Dynamic center-frequency shifting closes DWDM flex-grid spectrum gaps, increasing channel capacity without service-disrupting shutdowns.
- Optical Path Routing With Integrated Transmission Mode Selection
An auxiliary graph links route, frequency, and transmission mode selection to avoid suboptimal optical path design in multi-mode networks.
- Coherent Optical Reception with Subcarrier Dispersion Compensation
Subcarrier-by-subcarrier dispersion and delay compensation cuts equalization circuit scale and power in long-distance coherent optical reception.
- Optical Add/Drop Multiplexer With Redundant Wavelength Failover
Redundant wavelength selectors take over when a primary switch develops an abnormality, preserving stable transmission and continuous optical operation.
