Splice Technologies, Inc. "RIBBON FIBER" series fusion splice protection sleeve is designed to accommodate 2 - 12 ribbon fiber. Stock lengths are 40mm, but are also available in a new 30mm length for smaller packaging requirements.

Our single strength member sleeve which has become an industry standard, has an after shrink diameter of 4.9 X 4.4mm, and utilizes a special glass member. Our dual strength member sleeve is designed to "sandwich" the ribbon, thus minimizing any undue stress on the fiber while maximizing fiber uniformity and retentivity. This option has an after shrink diameter of 5.7 X 4.9mm. , and is available in a variety of glass and special high temperature plastic strength member combinations. The tubes are clear to allow viewing of the fiber during and after splicing. The entire assembly is designed 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.
