FSM-80S fiber optic fusion splicer is core-to-core alignment single fiber splicer succeeding to FSM-60S.
In addition to ruggedized concept, which 60S created, the 80S has a series of new features, such as "Automated wind-protector and tube-heater" for quicker splicing cycle as well as fewer operation steps, "innovative carrying-case design" for quicker preparation, "powerful Li-ion battey" for longer operation, high resolution bigger LCD monitor, and "built-in operation manuals" in various languages.
Market is from backbone network installation to opto-electronics components production for quality splice
