The Signal Fire ZS-700 is an electrode designed for Signal Fire fusion splicers, including AI-7, AI-7S, AI-7C, AI-7V, AI-8, AI-8C, AI-9, AI-10, and AI-20. Made from high-quality tungsten alloy, it ensures stable arc discharge and minimizes splicing loss. With strong compatibility and easy replacement, it supports 3,000 to 5,000 discharges under normal use. Widely used in fiber optic communication projects, FTTH network deployment, data center cabling, and broadcasting/power communication maintenance, regular inspection and replacement of electrodes help maintain consistent splicing quality.
