Subphoton - Submarine telecommunication systems, timeline

Smart Repeater

In the last months of 2025 the development of the Smart Repeater was started.

As part of the SENSOMAR project, the development of a Smart Repeater was started. The SENSOMAR project was activated by the Italian "Ministero della Difesa" and assigned to a group of companies and universities with Fincantieri S.p.A. as main contractor. Subphoton is mainly involved in the development of a submarine smart repeater that, by means of included additiona sensors, has the goal to monitor submarine heartquakes for real-time heartquake or tsunami alerts and environmental parameters for climatic models analysis. Furtehrmore the sensors installed inside the repeater allows the real-time protection of the telecommunication infrastructure against possible attacks.

BU design

The Branching Unit development was started.

While working to improve OSLA and OWI prototypes characteristics, the development of the full matrix fibre switching Branching Unit was started.

Submarine repeater qualification

The qualification phase for the Optical Repeater was completed by the end of 2024.

The qualification phase, including hydraulic pressure resistance, on the 48 fiber pairs Optical Repeater prototype were completed at Global Marine test facility in Chelmsford.

OSLA and OWI First Prototypes

Both Optical Repeater (OSLA) and Open Wetplan Interface (OWI) prototypes were completed.

During the first half of 2024 the first prototypes for the Optical Repeater and for the Open Wetplan Interface were completed, to make them available for the testing phase.

New headquarters

The company headquanters is moved to Via Privata Oslavia, 28 in Milan (ITALY).

The new location for the company headquarters offers wider spaces for the employees and laboratory activities, as required by the growth of the company.

The products planning for development and production is detailed by evaluating timeframe, required resources and budget.

The product planning is defined in detail, as required for the starting of the development and for the presentation of the project to financial investors.
A financial contribution from "Bando Brevetti 2019" is gained for a project related to submarine repeater mechanical structure analysis.

Company constitution

The Subphoton Srl company is constituted on December 2018

The stackholders decide for the company foundation during 2018, after the definition of the strategic scenario on the products and the related business plan.
