Multiplex System Selection Arrangements TRIZ Cases
- Tunable DWDM OTDR Monitoring with Passive Fiber Link Selection
A tunable DWDM OTDR and passive multiplexer select active fiber links without remote power or data communication.
- Mesh-Based PON Fault Detection for Geographic Fiber Localization
Loss notifications from multiple LMTUs feed a wireless mesh overlay, letting back-end servers localize fiber faults before technician dispatch.
- Transmission Frame Mapping with 257-Bit Code-Block Interleaving
Code-block interleaving combines multiple service streams before frame mapping, reducing complex synchronization with more efficient 257-bit blocks.
- Hybrid Data Center Routing With Electrical and Optical Switching
Electrical switches and optical cross-connects route diverse data flows by type, reducing conversions, congestion, delay, energy use, and cost.
- OLT Optical Carrier Regeneration for Low-Cost Coherent PON
OLT-generated optical carriers let ONU receivers perform coherent detection without local oscillators, reducing access-network hardware complexity and cost.
- FTTH Distribution Cell Cross-Connection for Progressive GPON Port Activation
Cross-connecting ODP and OSJ splitter fibres enables progressive GPON port activation as customer penetration grows, reducing hardware investment.
- Combo ONU Optical Module Circuit With Signal-Driven Switching
Signal-level detection automatically selects GPON or XGSPON, switches the path, and supplies power without manual transmission control.
- PON Splitter Port Identification Using Wavelength-Tunable Reflection
Tunable test light and reflection peaks map each ONT to a splitter port, reducing manual recording and speeding PON fault locating.
- Optical Communication Switching With Destination-Based Wavelength Routing
Destination-based wavelength assignment routes optical signals through a switch, avoiding electrical conversion delays in optical access networks.
- ONU–OLT Upstream Allocation for Dynamic Mobile Fronthaul
Changing packet lengths and rates trigger ONU updates to the OLT allocation map, reducing buffering and latency in mobile fronthaul.
- Binary-Tree Switch LiDAR for Lower Power and Better Light Reception
A binary-tree network of 2×2 switches routes LiDAR light with fewer active components, reducing power use and improving reception efficiency.
- Wavelength-Selective Optical Router for Low-Loss Transceiver Links
Wavelength-selective paths direct signals between multiple transceivers without random steering or relay complexity, reducing optical energy loss.
- Wavelength Multiplexer/Demultiplexer Adhesive Mounting for Low Insertion Loss
A cured adhesive fixes substrate surfaces without touching the multilayer film, limiting thermal tilt and insertion loss.
- Waveguide-End Scattering Monitor for PIC Optical Interfaces
Adjacent PIN or avalanche photodiodes use scattered light to distinguish light-source faults from optical-coupling issues.
- Tunable Optical Add/Drop Multiplexer With Angle-Based Wavelength Routing
Dynamic beam-angle adjustment selects wavelengths and routes transmitted or reflected beams, reducing manual reconfiguration in optical networks.
