Splice Technologies' "Micro" series fusion splice protection sleeve is designed specifically for use in optical splitter/coupler or similar packages, with an after shrink diameter of 1.5mm, while accommodating up to a 450um diameter fiber. Stock lengths are 25 and 40mm. This product is constructed with an inner EVA meltable adhesive tube, stainless steel strength member and a polyolefin heat shrink outer tube. The tubes are clear to allow viewing the color of the fiber after splicing. This product has been proportionately downsized using the same core materials, formulations and manufacturing processes that are used in our "Standard" series product. The entire assembly is heat bonded to ensure that all members maintain perfect alignment during shipping, handling and shrinking. We are proud to say that all of our products are made here in the USA and most sleeves are in stock ready for immediate delivery.
