Revolutionising physical-layer network reliability for hyperscale data centres and critical telecommunications infrastructures. Transforming passive testing into active, closed-loop optical self-healing and boosting legacy brownfield links from 1G to 40G without civil excavation.
Why traditional 8-bit OTDRs fail in high-density data centres, and how CableHunt's 4,096-level quantization captures sub-millivolt Rayleigh backscatter anomalies in real time.
16x vertical enhancement enables CableHunt to differentiate between natural glass attenuation slopes and micro-structural decay down to 0.05 dB.
Incorporating a single-mode launch spool shifts initial Fresnel saturation outside the measurement window, isolating ODF patch faults under 0.8 metres.
Powered by isolated 5V/3A DC battery systems, completely eliminating 50Hz/60Hz AC mains ground loops that typically distort sensitive optical front-ends.

Utilising sophisticated image recognition and signal classification, the apparatus automatically adapts its pulse widths, acquisition time, and testing parameters based on the specific type and condition of the cable examined.
By integrating RF over Fiber modulation, a single apparatus tests electrical, coaxial, twisted pair, optical single-mode, and hybrid cables without requiring separate testing sets or third-party adapters.
Engineered to meet stringent fire performance regulations and certified under MICE (Mechanical, Ingress, Climatic, Electromagnetic) standards, ensuring dependable field operation in harsh telecom trenches and server halls.
How CableHunt bypasses multimillion-pound civil excavation costs by modernising legacy brownfield single-mode fibre directly to 40G line rates in software.
Data centres and enterprise campuses in the London Docklands, Slough, and Birmingham corridors are constrained by legacy 1G fibre runs installed decades ago. Traditional upgrades require trenching roads, pulling new high-count ribbon cables, and risking massive service interruptions.
CableHunt combines dynamic chromatic dispersion compensation with out-of-band spectral allocation to safely drive 40G QSFP28 and SFP+ transceivers over existing glassβsaving up to 88% of capital expenditures.

Autonomous multi-band wavelength allocation covering the entire ITU-T optical spectrum (1260nm to 1675nm) to dynamically bypass local fibre attenuation peaks.
The CableHunt optimisation engine minimises cumulative physical attenuation, non-linear distortion (Four-Wave Mixing and Self-Phase Modulation), and splice decay across N operational channels:
Subject to: Pmin ≤ Pi ≤ Pmax, λi ∈ [1260 nm, 1675 nm], and OSNRi ≥ OSNRthreshold.
Toggle operating wavelengths to observe real-time attenuation coefficients and automated remediation actions.
From diagnostic detection to active physical remediation: watching CableHunt inject automated Cisco IOS and MikroTik CLI commands over Netmiko in real time.
Unlike conventional monitoring tools that merely sound late alarms when links drop (RX_LOS), CableHunt intervenes programmatically before catastrophic disconnection occurs.

Establishes an autonomous, closed-loop self-healing optical architecture that fuses high-speed 12-bit Rayleigh backscatter waveforms with SFF-8472 DDM transceiver telemetry using a hybrid 1D-CNN + Time-Series Transformer (TST) model, directly triggering automated Cisco IOS and MikroTik RouterOS protection switching within 41.8 ms.
Conventional systems either poll slow I2C scalars without spatial location or run offline 8-bit OTDR scans taking seconds. This work introduces the physics-informed Optical Sag Ratio (Sopt), detecting laser thermal fatigue and micro-bends hours before a hard RX_LOS link drop occurs and reducing spatial localisation error by 95.3% (0.015 m vs. 0.320 m).
For data centres, financial exchanges, and broadband operators, outages cost thousands of pounds per minute. This invention eliminates human troubleshooting delayβreducing Mean Time To Repair (MTTR) from hours of van dispatches to <50 ms carrier-grade autonomous switching while pinpointing physical cable damage to the exact centimetre.

Presents the complete hardware architecture of a 4-channel synchronous 12-bit native ADC reflectometer (4,096 vertical levels at 1.25 GSa/s, 25 Mpts) paired with a floating-ground DC isolation barrier and a 50 Ω impedance-matched InGaAs PIN-TIA photodetector (1100β1700 nm).
Overcomes the 256-level staircase noise floor of legacy 8-bit OTDRs by achieving a 16× finer voltage step (195.3 μV) and +24.08 dB SQNR improvement, while simultaneously cross-triggering on analog optical envelopes (CH1), I2C SCL/SDA frames (CH2/CH3), and RX_LOS interrupts (CH4) with an Event Dead Zone of 0.75 m.
Reduces optical front-end hardware procurement cost by 85% (£85 PIN-TIA / £450 edge unit vs. £3,800β£5,200 legacy benchtop units) while allowing data centre engineers to resolve closely spaced patch-panel connectors (<0.8 m apart) that appear merged and invisible on traditional field OTDRs.

Formulates a bounded non-linear spectral optimisation model (L-BFGS-B) across all six ITU-T optical bands (O, E, S, C, L, and U: 1260β1675 nm) to multiply legacy 1 Gbps G.652 single-mode fibre capacity straight to 40 Gbps (4×10G CWDM/DWDM) over existing underground ducts.
Maps high-resolution 12-bit backscatter profiles into a wavelength-dependent transfer function that automatically avoids the 1383 nm OH− water-peak and bounds nonlinear Kerr penalties (SPM, XPM, and FWM), while reserving the U-band (1625β1675 nm) for in-service out-of-band 12-bit reflectometry.
Civil street excavation in UK urban corridors costs £70,000β£140,000 per km and requires months of municipal permits. This breakthrough delivers a 40× bandwidth upgrade on already-buried glass in hours, saving telecom operators and enterprise customers 80%β96% in CapEx with zero civil works.

Academic researcher and systems programmer. Principal architect of the core 12-bit ADC testbed, optical digital signal processing (DSP) pipeline, proprietary spectral optimisation models, and Netmiko switch drivers.
CableHunt is committed to verifiable British engineering. Following our initial research breakthroughs published between January and April 2025, our core Python 12-bit DSP acquisition suite, Bellcore .SOR parser, and Netmiko switch drivers were released on GitHub in April 2025. Our flagship physics-informed Smart Optical AI Model (cablehunt-optical-ai) on Hugging Face is scheduled for public weights release in 2029 following multi-year UK Telecoms Security Act (TSA) Critical National Infrastructure safety verification.
By deploying our adaptive spectral optimisation engine, we dynamically assess physical chromatic dispersion, water peak degradation (E-Band), and non-linear penalties across all ITU-T windows. We then modulate optical power and shift active channels to low-loss windows, enabling 40G QSFP28/SFP+ transceivers to transmit reliably over existing glass without digging or pulling cables.
Traditional field units operate at 8-bit resolution (256 discrete levels), meaning micro-bends, slight splice decay, and transient reflections are drowned in quantization noise. CableHunt's native 12-bit architecture yields 4,096 levels (16x vertical enhancement), capturing sub-millivolt slopes and providing an event dead zone under 0.8 metres.
Our edge controller connects via SSH/NETCONF directly to core switches (e.g. Cisco IE-3000 or MikroTik CRS). When the 1D-CNN classifies an impairment (e.g. a macrobend or laser sag), it injects targeted CLI commands to adjust optical transmit thresholds or reallocate wavelength profiles in less than 50 milliseconds with zero dropped packets.
