The Subsea Wireless Group has released its SWiGoptical Level 1 industry specification, a new standard designed to enable interoperability between optical communication devices used in subsea environments. The protocol, managed by OTM Networks, provides a common framework for wireless optical data exchange across different manufacturers.
Why it matters
The standard aims to reduce the integration complexity and deployment risks inherent in building digitally connected subsea infrastructure. By standardizing communication protocols, it supports the scalability of autonomous subsea operations.
The SWiGoptical Level 1 specification establishes a common protocol framework for wireless optical data exchange. This follows the group's previous standards for acoustic, radio frequency, inductive, and hybrid communication technologies.
The players
Subsea Wireless Group
An industry alliance of 27 organizations dedicated to developing standardized communication protocols for underwater operations.
OTM Networks
A management firm and part of Sagentia Innovation that oversees the administration of the Subsea Wireless Group.
The details
The SWiGoptical Level 1 standard provides a unified communication interface for free-space optical systems, which transmit data using light beams rather than physical cables. This protocol allows devices from different manufacturers to share a common data exchange method, essentially functioning as a universal language for subsea hardware. The group is currently developing Level 2 and Level 3 specifications to expand these capabilities.
Timeline
October 28, 2026: The Subsea Wireless Group released the SWiGoptical Level 1 standard.
The Tech Race
This release marks an expansion of the group's portfolio beyond acoustic and radio frequency communication standards. The development of Level 2 and Level 3 specifications remains ongoing, signaling a multi-stage approach to full subsea interoperability.
Manufacturers and operators of autonomous subsea systems gain a clearer path toward integrating hardware from different vendors. The primary benefit is reduced deployment risk and simplified connectivity, though developers should monitor the upcoming Level 2 and 3 specs for future feature sets.
The takeaway
The SWiGoptical Level 1 standard establishes the first industry-wide baseline for subsea optical interoperability. Interested parties should watch for the release of Level 2 and Level 3 specifications, which will define the next phase of communication capabilities.
