Considerations for Zero-Buoyancy Cables

• Cable Design: Zero-buoyancy cables often require specialized fillers, sheathing, and armoring to achieve neutral buoyancy in water.
• Testing and Certification: Look for manufacturers with ISO, NABL, and IEC certifications and in-house testing facilities for mechanical, water-blocking, and tensile performance.
• Experience with Submarine or OPGW Cables: Manufacturers with a track record in OPGW, ADSS, or submarine fiber cables are more likely to meet zero-buoyancy requirements.
