Fiber Optic Mechanical Splice

When you find out that you have a broken fiber, you have a few questions to ask, Do I need to replace the fiber? Can I splice it? Do I need a fusion splicer? FIS Mechanical Splices hold fiber with a self-gripping clamshell design. These unique splices also allow for the optional use of cyanoacrylate adhesive (e.g. Super Glue) to achieve a superior pull strength of 1.5 lbs. The splices fit into any mechanical splice style splice tray, accommodate 125µm clad fiber (singlemode or multimode) and have a typical loss of .2dB. The splices are also available in our new FIS Mechanical Splice Kit that includes 6 FIS Mechanical Splices, Jacket/Buffer Stripper, Field Cleaver, Adhesive, Optic Prep Wipes and Instructions.

Mechanical Splice KitSimple Tools Required:

• Buffer and Coating Stripper
• Fiber Optic Cleaver
• Isopropyl Alcohol
• Lint-Free Wipes
• Cyanocrylate Adhesive (e.g. Super Glue)
• Visual Fault Locator (not included in kit)

Please follow the Steps below for a successful Mechanical splice assembly.

Step 1:

Strip back fiber buffer and coating 1.5 inches from the fiber tip. Clean stripped fiber with Isopropyl Alcohol and Lint-Free Wipe.
Step 1

Step 2:

Cleave fiber to 14mm in length. Clean the cleaved fiber with Isopropyl Alcohol and Lint-Free Wipe.
Step 1

Step 3:

Insert first fiber tip mid way into the v-groove of the splice core. Insert the second fiber tip into the splice core until it butts up against the first fiber.
Step 1


A Visual Fault Locator (VFL) can be used to optimize the connection. Inject light from the VFL into one of the fibers and insert the cleaved end mid-way through the splice core. This will cause the core to illuminate. Insert the second fiber into the opposite side of the splice core. When the two fiber ends are mated properly, the splice core will stop illuminating.

Step 4:

Lay the splice core with the joined fibers into the bottom shell of the splice housing. Snap the top shell onto the bottom shell to complete the assembly. If you wish to make this a permanent splice, place a drop of quick curing adhesive into each epoxy hole in the top shell of the splice.
