Includes: Refurbished Fitel S121m hand-held fusion splicer, 2 battery packs w/recharger, ac adapter & US power cord, and instruction manual. Kit includes Fitel s323 cleaver, pair 250um fiber holders, spare pair electrodes, and Fitel hard plastic case w/carrying strap.

Currently we are out of stock on the S121A model, but we do have the Fitel S121M, which can do up to 4 fibers at once!

Every once in a while a S121A model will come in and may not be shown on the website, please call us for availability.

The S121A Fusion Splicer has been reduced in both size and weight to roughly 1/3 that of Furukawa Electric's previous model. The unit itself weighs 980g, and a total of 1,150g even with the removable battery included. The adoption of an original T-shaped body enables connections using a minimum excess fibre length when the fibre head is inserted into the enclosure, and at the same time allows the user to hold the fusion splicer in one hand when conducting operations in locations with insufficient working space. The S121A also comes with a standard soft carrying case and strap, so that it can be carried around the user's neck or attached to a belt, making it as portable as a camera.

The S121A Fusion Splicer handles only single-core optical fibres. As in the case of previous models, the fibre is set in the holder, and the unit executes all operations from pre-processing to connection, so anyone can operate the unit with ease. An enlarged image of the fibre is displayed using a CCD camera and a 2.5-inch colour LCD monitor, to ensure stable, high-quality connections. This product offers fast, fully automatic connections in only 13 seconds - all the user needs to do is set the fibre in the holder and press a button. The optical fibre connection type can be switched easily between single fibre mode and multi-mode by selecting a pre-set connection program, and an operation guide is displayed on the screen for even greater ease of use.

The unit offers two power supplies; a removable, rechargeable battery, and an optional DC adaptor to allow AC power input. Furthermore, by attaching an optional sleeve heater or simple reinforcement tool to the back of the unit, connections can be strengthened using popular Japanese thermal protection sleeves or the ULTRAsleeve, which is used extensively in the United States. The S121A thus offers all the functions required to increase reliability and ease of connection operations, and at the same time has excluded loss estimation functions and connection inspection using high-resolution image processing. It ensures very low connection loss in terminal connections (average 0.1 dB or less in the case of single mode fibre connections), and provides advanced cost performance in terms of operability, reliability, and economy.
