1. Product Overview<\/strong>
\nOur Submarine Optical Fiber is a high-performance, ultra-low-loss single-mode optical fiber specially engineered for subsea and underwater communication systems. Adopting advanced pure silica core manufacturing technology, this fiber features minimal signal attenuation, large effective transmission area, and exceptional pressure and corrosion resistance. It is fully compliant with international ITU-T G.654 series standards, perfectly adapting to long-distance, high-capacity, and high-stability underwater data transmission scenarios. Widely applicable to transoceanic backbone cables, coastal communication links, offshore engineering communication, and marine observation network construction, it serves as the core transmission medium for global subsea communication infrastructure.<\/p>\n

2. Core Product Features<\/strong>
\n– Ultra-Low Transmission Loss: Optimized pure silica core design achieves a typical attenuation of 0.158 dB\/km, effectively reducing signal amplification requirements and supporting ultra-long-span stable transmission up to 6000km for repeatered systems and 400km+ for unrepeatered systems, greatly lowering subsea project operation and maintenance costs.
\n– High Capacity & Broadband Compatibility: Large effective area structure eliminates nonlinear optical effects, perfectly compatible with 100G\/400G\/800G high-speed transmission and SDM (Space Division Multiplexing) systems, supporting ultra-large-capacity data transmission to meet the explosive growth of global cross-border communication and cloud data interconnection demands.
\n– Extreme Subsea Environment Resistance: Customized high-strength coating and reinforced structural design deliver excellent seawater corrosion resistance, deep water pressure resistance, and tensile resistance. It stably operates in 1000\u20138000m deep-sea environments and adapts to complex seabed terrains such as sandy, rocky and muddy seabeds.
\n– Superior Long-Term Stability: Strictly manufactured in accordance with IEC 60794 and international submarine cable specifications, with low fatigue and low aging characteristics. It maintains consistent optical performance throughout the 25+ year service life, avoiding signal attenuation fluctuations caused by seawater erosion and deep-sea pressure changes.
\n– Diversified Matching & Easy Construction: Supports multiple core configurations and coating diameter specifications, compatible with various submarine cable armoring structures (lightweight, single-layer\/double-layer steel wire armoring). Suitable for both repeatered and unrepeatered subsea cable systems, simplifying on-site laying and system integration.<\/p>\n

3. Application Scenarios<\/strong>
\n– Global transoceanic & cross-regional submarine communication backbone networks
\n– Coastal city communication interconnection & island-to-island link projects
\n– Offshore oil & gas platform communication and underwater engineering monitoring systems
\n– Marine scientific observation networks, underwater detection and data transmission equipment
\n– International data center interconnection and long-distance low-latency communication projects<\/p>\n
