If you have ever spent a wet Tuesday morning in a freezing roadside cabinet somewhere near Birmingham trying to diagnose a dying optical link, you already know our pain.
For the last forty years, physical optical testing has been bloody slow and mostly passive:
- A customer rings up screaming because packets are dropping.
- A tech hops in a van with an ancient 8-bit OTDR that weighs as much as a bowling ball.
- You squint at a jagged, staircase-looking trace on a tiny screen, trying to figure out if that tiny blip at 42.1 km is a degrading splice, a pinched duct, or just ADC sampling noise.
- And if the customer wants 40G instead of 1G? Tough luck. You usually have to wait six months for council street-works permits and spend £70,000 to £140,000 per kilometre tearing up tarmac to pull fresh glass.
We got tired of that nonsense.
CableHunt is a hardware + software engineering platform designed in the UK to do two things properly:
- Show you what is actually happening inside the glass at 16× finer vertical resolution (12-bit native sampling, 4,096 vertical levels) than legacy 8-bit field tools.
- Upgrade existing brownfield 1G single-mode links straight to 40G purely using high-resolution channel profiling, chromatic dispersion pre-compensation, and ITU-T wavelength tuning — no trenching, no council permits, and no noisy diggers outside anyone's window.
Here is the engineering explained without the glossy corporate marketing waffle:
Most field OTDRs still rely on 8-bit converters (
We sample natively at 12-bit (

16 times finer vertical resolution and
$72.2\text{ dB}$ effective dynamic range. - Spots microscopic microbends and gradual fusion-splice degradation down to
$0.05\text{ dB}$ — typically 2 to 3 weeks before the fibre snaps. - Event dead-zone under
$0.8\text{ metres}$ , so if someone pinched an SC/APC patch lead right behind the ODF rack, you see it straight away instead of guessing.
Thousands of kilometres of G.652 glass laid twenty years ago are still throttled at 1 Gbps because operators are terrified that unmapped microbends,
Instead of ripping out the duct, we run a 12-bit spectral sweep across
Finding a fault is nice, but fixing it before TCP sessions drop is much better.
Our edge daemon talks straight to core switches (Cisco IOS-XR, MikroTik RouterOS v7, Arista EOS, Juniper Junos) over Python Netmiko / SSHv2 fast-sockets. When our 12-bit sensor notices an L-Band (
We packed dual-domain TDR (for copper/coax/hybrid lines), 12-bit OTDR, RF over Fiber (RFOF), and a 400× IEC 61300-3-35 coaxial ferrule microscope into an anodised aluminium chassis with a

Unlike generic language models, cablehunt-optical-ai is a purpose-built, physics-informed Hybrid 1D-CNN + Spectral Transformer Foundation Model trained directly on 12-bit raw ADC backscatter arrays and Bellcore .SOR traces:
- Multi-Scale 1D-CNN Front-End: Scans 4,096-level Rayleigh backscatter waveforms to classify reflective and non-reflective events (fusion splice decay, physical macrobend pinch, dirty SC/APC ferrule, ghost reflection, or clean termination) in under 12 milliseconds with >98.4% field accuracy.
-
Differential Wavelength Physics Layer (
$\Delta\alpha_{1625/1550}$ ): Compares$1550\text{ nm}$ C-Band against$1625\text{ nm}/1650\text{ nm}$ L/U-Band evanescent mode-field leakage to tell the difference between a harmless thermal splice drift and a physical digger crushing a roadside duct. -

$-0.08\text{ dB}$ micro-stress crosses the FEC bit-error cliff, and synthesises safe Netmiko CLI remediation commands.
Why is the Smart AI Model confirmed for open release in 2029 (while the software stack & research findings released in Jan–April 2025)?
An honest engineering answer: Critical National Infrastructure (CNI) security and physical laser safety.
This model directly controls optical launch power, DWDM channel allocation, and core router failover scripts across live telecom backbones. If an insufficiently hardened model is tricked by adversarial optical pulse injection or hallucinates a power boost, it can blind sensitive InGaAs APD receivers, breach Class 1M laser safety limits, or flap regional routing tables.
Therefore, we operate a strict Two-Stage Open Release Schedule:
