Photaxon FiberSpider — Distributed FTTH Research Laboratory

FiberSpider is a Photaxon research and development project focused on studying a possible evolution of FTTH architectures.

The goal is not simply to automate a traditional FTTH network, but to study a model in which part of the network intelligence and control can be distributed across multiple nodes or intelligent cabinets.

The central principle is to separate:

• stable logical identity;
• persistent network state;
• dynamic physical path;
• decisions assisted by intelligent agents;
• deterministic validation of operations.

The software laboratory is used to verify these concepts before future integration with real GPON hardware.

In traditional FTTH networks, many operational activities depend on network information and physical paths defined in advance.

In the field, however, the following can occur:

• topology changes;
• ports different from those expected;
• new splitters;
• new splice closures or PTEs;
• network expansions;
• discrepancies between documentation and the physical situation;
• interventions that change the actual fiber path.

FiberSpider studies a system in which the technician remains essential in describing what really happens in the field, while the system dynamically updates and validates the network state.

ALEX is the public frontend node.

• Photaxon website;
• FiberSpider dashboard;
• technician interface;
• Apache HTTPS;
• reverse proxy to the backend.

ALEX does not access the database directly.

RAGNO is the main FiberSpider laboratory node.

• FastAPI backend;
• FiberSpider agents;
• experimental LLM runtime;
• deterministic logic;
• cabinet simulation;
• OpenStack / Neutron integration;
• activation workflow;
• FTTH topology simulation.

AAA is the persistence node.

• PostgreSQL;
• network state;
• authorized technicians;
• activation requests;
• OTP challenges;
• cabinets;
• FTTH lines;
• splitters;
• ONTs;
• ports;
• transactions;
• anomalies;
• states and resources.

The cabinets represent distributed FTTH nodes able to maintain information about their own state and cooperate with the FiberSpider system.

In the current laboratory these nodes are simulated through software and virtual infrastructure.

The future objective is to turn the concept into real active cabinets equipped with:

• mini-PC;
• FiberSpider agent;
• telemetry;
• PON/OLT interface;
• sensors;
• local technician authentication;
• communication with other nodes.

FiberSpider does not give direct network control to a language model.

The principle is:

LLM PROPOSES → BACKEND VALIDATES → DATABASE PERSISTS → NETWORK ACTION

The LLM agent can interpret information provided by the technician, analyze a situation and propose a possible action.

The operational decision must be verified by deterministic logic, policy, network state and authorizations.

The LLM must not have unrestricted access to the shell or infrastructure.

The software proof of concept includes a real workflow for technician identification.

The WR is currently registered as a reference. Automatic WR validation has not yet been implemented. Physical GPON provisioning is not performed yet.

One planned evolution for the FiberSpider cabinet is a system called:

Proof of Field Presence — PoFP

Its purpose is to verify not only that the technician is authorized, but also that they are physically present in front of the cabinet on which they must work.

The future workflow could become:

NFC IS FUTURE HARDWARE RESEARCH and is not an installed feature.

NFC should not rely only on a static identifier that can be easily copied.

The backend verifies:

• technician;
• WR;
• cabinet;
• challenge;
• timestamp;
• session validity.

This makes it much harder to delegate an authorized job to a different person.

GPS location may eventually be used as an additional signal, but not as the sole presence verification system.

WORKING IN SOFTWARE:

• FastAPI backend;
• technician authorization through PostgreSQL;
• Telegram OTP;
• OTP verification;
• request persistence;
• PostgreSQL schema and state;
• FiberSpider agents;
• experimental LLM runtime;
• OpenStack / Neutron;
• Photaxon public frontend;
• distributed ALEX / RAGNO / AAA architecture.

IMPLEMENTED AS A COMPONENT BUT NOT FULLY CONNECTED TO THE WEB FLOW:

• resource leases;
• resource state machine;
• LLM agent proposals in the operational workflow.

SIMULATED:

• ONT identification;
• physical FTTH path;
• provisioning;
• GPON / OLT;
• physical fiber switching;
• technical provisioning closure.

FUTURE HARDWARE RESEARCH:

• real ONT;
• mini-OLT GPON;
• active FiberSpider cabinet;
• sensors;
• optical telemetry;
• NFC Proof of Field Presence;
• physical distributed nodes;
• field pilot project.

The software proof of concept is not the final product.

It provides a basis for designing, verifying and later prototyping a new generation of distributed FTTH infrastructure.

Photaxon is interested in collaboration with:

• telecommunications operators;
• universities;
• research institutes;
• optical equipment manufacturers;
• hardware manufacturers;
• OpenStack / networking partners;
• research programs;
• parties interested in funding the hardware phase;
• territories available for pilot projects.

FiberSpider is published to enable technical evaluation of the idea and proof of concept.
