Electro-Optical Cables

High-performance cables that carry electrical power and optical signals in harsh environments.

Electro-optical cables for power, data, and signal applications

Rochester Cable designs and manufactures electro-optical cables that combine optical fibers and electrical conductors in a single cable construction. Built for harsh subsea, offshore, defense, oceanographic, and industrial environments, these cables support applications that require power, control, high-speed data, video, telemetry, or sensing performance.
 
Our electro-optical cable designs can be configured around the application, fiber requirements, conductor needs, mechanical protection, and operating environment.

Built for power, data, and harsh environments

Electro-optical cable projects often combine demanding electrical, optical, mechanical, and environmental requirements. Rochester Cable works with customers to develop cable constructions that align with system architecture, deployment conditions, and long-term performance expectations. Key design priorities include: 

Optical data

Fiber elements can support high-speed data, real-time video, sensing, telemetry, and communications over distance.

Power and control

Electrical conductors can be incorporated to support power delivery, control signals, or other system requirements.

Armor and strength

Cable constructions can be designed with strength members, armor systems, and protective materials to support handling, deployment, towing, or dynamic operation.

Built for conditions

Material and construction choices can be reviewed for harsh conditions where pressure, immersion, flexure, abrasion, temperature, or corrosion may affect performance.

Common electro-optical cable types

Rochester Cable can support a range of electro-optical cable constructions used across subsea, offshore, defense, oceanographic, and harsh-environment systems.
