Marine System Solutions

ZTT provides comprehensive marine system solutions tailored for power transmission, communication networks, offshore oil & gas platforms, and offshore wind energy. With industry-leading technologies, robust engineering capabilities, and a strong track record in global deployments, we connect continents, energize industries, and enable a more sustainable and connected world beneath the waves.

Industry Overview

Communication Transmission

This solution integrates solar, wind, and hydro energy infrastructure into urban and rural grids, paired with smart storage systems, to replace fossil fuel reliance and cut regional carbon emissions by 40% within a decade.

Industry Challenges

Bandwidth Demand

Meeting the exponential growth of global data with multi-core fiber capabilities.

Signal Attenuatio

Maintaining signal integrity over thousands of kilometers in deep-sea corridors.

Physical Security

Protecting fragile fibers from geological shifts and human activities (anchoring/fishing).

Our Solution

Our range includes Non-repeatered (LW/LWP) and Repeatered (SA/DA) submarine optical cables. We utilize high-strength steel wire armoring and hermetically sealed copper tubes to protect the fibers, supporting up to 16-pair or higher fiber counts.

Repeatered submarine optical cables

These cables feature a copper tape welded tube for power transmission to repeaters or sensors. The working voltage is customizable from 375 V to 20 kV. HDPE insulation ensures a system lifespan exceeding 25 years.

Non-repeatered submarine optical cables

Designed without power transmission capability. Supports single-mode or multi-mode fibers. Armoring configurations:

— DA (Double Armor)

— SA (Single Armor)

— LWP (Light Weight Protected)

— LW (Light Weight)

Cable Accessories

ZTT provides a comprehensive range of high-performance submarine cable accessories, including joints, terminations, and repair solutions, to ensure system integrity and longevity.

Value Contained

Ultra-High Capacity

Supports Terabit-level transmission to meet future-proof communication needs.

Exceptional Durability

Enhanced armoring techniques provide superior protection against external aggression.

Global Connectivity

Seamlessly linking continents with high-quality optical infrastructure.
