The Fujikura ELCT2-20A is a set of fusion splicer electrodes designed for Fujikura fusion splicers, including FSM-50S, FSM-50R, FSM-60S, FSM-60R, FSM-61S, FSM-61S+, FSM-70R, FSM-70R+, FSM-80C, FSM-80C+, FSM-80S, and FSM-80S+. Made from high-quality tungsten alloy, these electrodes provide stable arc discharge, reducing splicing loss and ensuring precise fiber alignment. They are highly compatible, easy to install, and support approximately 3,000 to 5,000 discharges under normal usage. Widely used in fiber optic communication, FTTH network deployment, data center cabling, and broadcasting/power communication maintenance, regular inspection and timely replacement of electrodes help maintain optimal splicing performance.
