Time-Division Optical Multiplex Systems TRIZ Cases
- Soliton Trapping for WDM Conversion in Passive Optical Networks
Non-linear soliton trapping converts single wavelengths to multiple channels, reducing passive optical network infrastructure costs and signal attenuation.
- Multi-Bit Rate Passive Optical Network OLT and ONU
An optical line termination unit switches downstream transmission bit rates to serve multiple optical network units, eliminating infrastructure duplication.
- Dynamic FEC Bit Adjustment for WDM OSNR Degradation
A dynamic forward error correction mechanism adjusts bit allocation to maintain coding gain.
- Hitless ODUflex Resizing via LCR Protocol
Autonomous nodes identify matching time slots through Link Connection Resizing protocol exchanges to enable dynamic bandwidth adjustments.
- De-emphasis Signal Generator Using Parallel Optical Modulators
A de-emphasis signal generator combines electrical inputs via parallel optical modulators to produce formatted optical signals.
- Random Channel Assignment in WDM Passive Optical Networks
A random channel assignment system enables selectionless optical network units to transmit any wavelength band.
- PON Access Fiber Testing Using Tunable Laser and AWG
An OTDR system uses a cyclic AWG and WDM couplers to isolate access fiber segments, resolving signal loss issues during break detection.
- Optical Time Sequence Cache for Dynamic Scene Processing
An optical time sequence cache maps spatial information to temporal sequences using SMUX and WMUX technologies.
- WDM Transport Transmitter Intra-Nodal Redundancy
A WDM transport transmitter replicates client signals across redundant paths to maintain continuous optical transmission.
