3. Installation of Interlocking Armor Fiber Cable

**Caution: Failure to follow proper pulling procedures, like pulling on the fiber cable directly or only pulling on the armor may result in fiber damage and void the manufacturer’s warranty. Make sure to follow the below best practices.

A. Attach wire mesh pulling grip

1. Determine the correct size pulling grip. Caution: if grip is too large it will slip on

the armor, if it is too small if will be difficult to install and may put additional stress

on the armor.

2. Mark the outer jacket at 18 to 24 inches from the open end. Ring cut and slit the

jacket. Remove the outer jacket from the armor, (See picture A below). Then using

an armor cutting tool remove 18 to 24 inches of armor to expose the core cable,

(See picture B below)

3. Insert the cable and armor into the wire mesh pulling grip. Bring the core cable out

of the grip through the mesh as close to the pulling end as possible, or through the

“Basket” depending on the pulling grip being used. Make sure grip is pushed all

the way down until the tip of the armor is at the point where the cable exits the

grip.

4. Ring cut the core cable as close to the mesh grip as possible, remove the jacket to

expose the aramid yarn and fibers. Using appropriate fiber cutting shears trim the

buffered fibers, taking care to leave ALL the aramid yarn intact.

5. Twist the yarn into a manageable bunch and tie securely to the pulling eye of the

mesh grip.

All Rights Reserved

6. Slide the armor and core cable back into the mesh grip until the aramid yarn is

tight. Using electrical tape cover the aramid yarn to protect it during the pulling

process. Also, tape the mesh grip to the armor at the entry point.

7. Attach a properly rated swivel to the pulling eye of the mesh grip and install the

cable. Take caution not to exceed the maximum pulling tension or bend radius of

the fiber cable.

8. After completion of the pull, remove the pulling grip. Measure and mark 48 inches

from the end of the armor. Using the armor cutting tool, remove the armor, then

cut the cable at the armor exit and discard. Secure the cable. Tape the end to

prevent ingress of foreign materials.

B. Preparing the Interlocking Armor Cable for Termination

1. After determining the amount of fiber cable needed for proper termination, make a

ring cut in the outer jacket.

2. Make a second ring cut in the outer jacket 1 to 1-1/2 inches from the first ring cut.

Split the outer jacket between the two cuts and remove the outer jacket.

3. Using the armor slitting tool, place the cable in the cable guide, tighten the

thumbscrew and rotate the handle until the armor is cut. The tool is designed to cut

through with only one revolution of the cutter to protect the fiber cable inside.

4. Using a twisting motion, separate the armor at the cut and remove the armor from

the fiber cable.

5. Insert the fiber cable into either the MC connector, if mounting inside a metal box,

or inside the American NWT Connector if installing on a rack mount bracket, RMB.

Push the connector up to the armor and attach to the end of the armor section

using the appropriate method for the connector being used. This will provide

protection from the sharp metal edges and allow for proper bonding of the cable.

Note: To ensure proper bonding of the metal, make sure the connectors are in

solid contact with the bare metal of the cable.

4. Mounting options for RMB and BAF brackets:

A. RMB and BAF mount to the rear or inside rails of the cabinet or rack based

on best alignment of cables to fiber shelves.

B. Examples of RMB mounting options

6. Should Interlocking Armored Cables be Bonded to Ground?

7. Contact information

Visit our website or contact your local CommScope representative for more information.

For technical assistance or customer support, visit us at:

http://www.commscope.com/SupportCenter

The simple answer is YES. Interlocking armor must be bonded to ground. When the cable run is started and terminated in a metal distribution box, the NEC approved MC connector will serve as the bond. Remember, the metal distribution box must be bonded to ground and the MC connector must be in direct contact with the bare metal of the armored cable.

If the armored cable enters into a rack or cabinet then the armored cables should be mounted onto the appropriate rack mounted bracket, RMB listed in section 2 using the appropriate sized NWT American connector from the list above in sections 1. The attachment of the metal NWT connector to the RMB will allow the cables to be bonded through the RMB if the NWT connector has solid contact with the bare metal of the armored cable.

The RMB must be bonded to the telecommunications grounding bus bar either directly using a properly sized bond strap or bonded to a bus bar in the cabinet or rack. If the cabinet and rack are properly bonded to the telecommunications grounding bus bar then a short bond strap, like the one listed in section 2 could be used to bond the RMB to the rack or cabinet.
