The crimp splice housing
is designed to protect the Norland Optical Splice and provide
full cable strength when splicing either simplex cable or
duplex zipper cable. Cable strength is achieved by crimping the Kevlar
strength member fibers between a metal collet and the central
housing. Shrink tubing is added to the ends to provide
additional strain relief and a weather tight seal.
This device requires a hexagonal crimp tool for
1/4" stock such as a Daniels HX4 with Y205 die. Final
crimp diameter is 0.213". It also requires a heat gun with temperatures to 125°C.
A. Before making splice.
1. Insert one shrink tube and one collet on each cable section.
Slide these pieces up out of the way. Slide central housing
onto one of the cable
2. Strip 2 inches of outer cable jacket from each cable. Fold
Kevlar fibers back out of the way of the buffered fiber.
3. Strip buffer coating off each optical fiber and cleave
to give approximately 1/2" of bare fiber extending from
4. Remove additional outer cable jacket to give a total of
1 3/4" of optical fiber extending from jacket.
5. Complete splice following splice assembly procedure.
After splice is completed.
1. Start with the collet which is on opposite side from central
housing. Slide it down to the end of the cable. Split Kevlar
into two equal bundles. Push collet 1/4" forward
over Kevlar and slip Kevlar to the back of the slots on collet.
Pull Kevlar snug so that cable end is flush with the back
of the slots. Fold Kevlar back and hold on collet.
2. Still holding collet and Kevlar, slide central housing
down onto collet and Kevlar. Push cable and collet further
into housing until Kevlar from opposite cable appears at opposite
3. Pull kevlar out. Split into two equal bundles. Slide second
collet forward until it is about 1/4" forward over Kevlar.
Slip Kevlar into back of slots on collet. Pull snug and fold
back and hold on collet.
4. Slide central housing back down over second collet. Do
not tug on cable. If fit is tight, gently push collet into
housing while pulling on cable at other side. Adjust both
collets so they are equidistant from ends of housing.
5. Crimp central housing to collets. Leave 1/16" lip
on end of housing. Trim excess kevlar off.
6. Slide shrink tubing over crimp area. Shrink down using
low heat (125°C) until adhesive inner wall melts and bonds
to cable. Be careful not to melt cable insulation.
