Product Description

The 3M brand Fibrlok II 2529 Universal Optical Fiber Splice is a high performance, easy-to-use, mechanical optical fiber splice. The Fibrlok II Universal Splice can be used with either single-mode or multimode fibers with a cladding diameter of 125 microns. It will accommodate any combination of fibers with coating diameters from 250 µm to 900 µm. In addition, the Universal Optical Fiber Splice incorporates a single cleave length for splicing both 250 and 900 micron coated fibers and provides the ability to "re-position" fibers for increased splicing yields.

The splice consists of four molded polymeric components and an aluminum alloy alignment element. The four polymeric components are Jacket, End Plug 2 , and Cap. The jacket is provided with a compartment to house the aluminum alloy element. The end plugs are attached to each end of the jacket and locate the element laterally within the splice jacket. Each splice end plug contains a fiber entry port which is used to guide either 250 or 900 micron coated optical fiber into the alignment element. During splice actuation, the cap acts on the element to align and secure the fibers within the splice.

The Fibrlok II Universal Optical Fiber Splice is an improved version of the original Fibrlok Optical Splice. The Universal Optical Fiber Splice element is constructed from the same ductile aluminum alloy as the original Fibrlok Splice element. All splice components are factory-assembled. An index matching gel is pre-installed in the splice element.

During assembly, the splice is held within the Fibrlok 2501 Assembly Tool. After the fibers are inserted into the splice, the cap is depressed with the Assembly Tool. The motion of the cap squeezes the "legs" of the element such that the "legs" come together. The fibers are permanently aligned and gripped in the fiber holding region of the splice when the cap is actuated.

After preparation, the fibers are inserted into the Fibrlok II Splice element. The assembly tool is then used to close the cap, forcing the clamping and locating surfaces against the fibers and aligning the fibers precisely and permanently in place.

Test Program Overview

To assess the long term performance of the Fibrlok II Universal Optical Fiber Splice, the splices were subjected to a number of tests which expose them to conditions which are more severe than those which are anticipated in actual use. The test samples used for all the tests were produced in the 3M Austin, Texas manufacturing facility. Testing of the splices occurred in the 3M Fiber Optics Test Laboratory in Austin. The tests are based upon telephone industry specifications and are believed to represent the most severe requirements in the industry. The tests described in this Technical Report were conducted using Corning SMF-28 250 micron coated fiber and Fibrlok II 2529 Universal Optical Fiber Splices. All splice samples were constructed using "heterogeneous" optical fiber of the same type but different lots . Initial loss and reflectance was measured with a Tektronix Fibermaster TFP2 OTDR using a 100 ns pulse width and the fiber manufacturer's recommended backscatter coefficient. All splices were prepared using square cleaves. A square cleave will provide worst case reflectance results.

Installation Conditions

The Installation Conditions testing is intended to analyze the actual operation of splicing fibers under a variety of installation conditions using high and low extremes for temperature and humidity.

Splices using single mode fiber were constructed under the following environmental conditions:

Test Low Temperature High Temperature High Humidity Low Humidity

Temperature 0°C 32°F
45°C 113°F 23°C 73°F 23°C 73°F
