M90 Corning Fusion Splicer

The Corning / Siecor M90 / 5000 Series Fusion Splicer is a microprocessor-controlled fusion splicer that is employed to produce mechanically strong, durable and low-loss connections between optical fibers.

It is possible to connect single-mode fibers, dispersion-shifted single-mode fibers and multimode fibers up to a maximum coating diameter of 900 µm. The splicer is designed for the standard fiber outside diameter 125 µm (without coating).

The fibers are positioned and fused automatically. This ensures consistently good results irrespective of the operator. Two mutually independent processes for positioning and automatic splice loss calculation are incorporated into the splicer. The proven LID system (LID = Local Injection and Detection) allows the user to perform exact core-to-core positioning of the fiber ends so that usable splice results can also be obtained in the case of single-mode fibers with eccentric cores. It also allows the user to measure the splice loss at the operating wavelength of 1300 nm. If the LID system cannot be used (e.g. in the case of tight buffered fibers), the finished splice is analyzed with the L-PAS video system (Lens Profile Alignment System) and the splice loss likewise given in dB.

The LID programs with automatic fusion time control measure the light transmitted through the fusion point during the fusion process. The optimum fusion time for each individual splice is thus selected automatically.
