4. Installing the Terminal
• If installing Armored SST-Ribbon™ Cable into this terminal, prepare and strain-relieve the cable
per the directions provided in the Corning Optical Communications Standard Recommended
Procedure 206-434.
4.1 Remove Cable Sheath
CAUTION: Fiber optic cable is sensitive to excessive pulling, bending, and crushing forces. Consult the
cable specication sheet for the cable you are installing. Do not bend the cable more sharply than the
minimum recommended bend radius. Do not apply more pulling force to the cable than specied. Do
not crush the cable or allow it to kink. Doing so may cause damage that can alter the transmission
characteristics of the cable; the cable may have to be replaced.
WARNING: Do not install telecommunications equipment or work with telephone wiring during
a lightning storm. Telephone lines can carry high voltages from lightning causing electrical shock
resulting in severe injury or death.
CAUTION: Recommend the use of safety glasses (spectacles) conforming to ANSI Z87, for eye
protection from accidental injury when handling chemicals, cables, or working with ber. Pieces of
glass ber are very sharp and have the potential to damage the eye.
CAUTION: The wearing of cut-resistant safety gloves to protect your hands from accidental injury
when using sharp-bladed tools and armored cable is strongly recommended. Use extreme care when
working with severed armor. There will be a sharp edge where armor is cut. To minimize the chance
of injury from the cut armor, cover the exposed edge with a wrap of electrical tape. To minimize the
chance of injury from sharp-bladed tools, always cut away from yourself and others. Dispose of used
blades and armor scrap properly.

Standard Recommended Procedure 206-337 | Issue 10 | August 2017 | Page 5 of 18
IMPORTANT: Typical lengths when using Corning Optical Communications’ SCF-ST-126 splice trays are
illustrated. Refer to instructions provided with your Corning Optical Communications splice tray.
Since the actual application may vary, it is recommended to route the buer tubes as they will lie
in the terminal to determine actual strip lengths before cutting ber. Refer to routing illustrations
Step 1: Remove cable sheath as described for your application:
• For midspan applications, remove the length of cable sheath and armor (where applicable) as
indicated in Figure 2 according to the manufacturer’s directions for the cable type being installed.
Figure 2
• For taut sheath applications, remove cable sheath as indicated in Figure 3. Taut sheath
applications are possible only in the SCA-9T34 terminal.
Figure 3
• For endspan applications where the cable will be terminated to pigtails, remove cable sheath as
shown in Figure 4.

4.4 Install Strain-relief Hardware
Installation of strain-relief brackets prevents pistoning or bowing of central strength members, as well as
cable sheath slipping or pullout. You will be required to strain-relieve the cables later in this procedure. When
instructed to strain-relieve a cable, refer to this section for the directions on doing so.
4.4.1 Strain-relief Brackets
Install strain-relief bracket(s) onto the opposite side (180 degrees) from the grounding clamp, if applicable:
Step 1: Place hose clamp over the cable and bracket 18 mm (0.75 inch) below the sheath end. Center the
sheath retention grip on the opposite side of the cable from the hose clamp tensioning body.
IMPORTANT: When using armored cable, install strain-relief bracket(s) onto the opposite side (180 degrees) from
the grounding clamp. Install the hose clamp and bracket 25 mm (1.0 inch) from the end of the
cable sheath to prevent the retention grip from overlapping the ground hardware.
Step 2: Tighten the hose clamp in the notch on the bracket with the tensioning body on the hose clamp
against the bracket. Tighten hose clamp to a torque value of 30 in-lb.
4.4.2 Nonmetallic Strength Members
• In ribbon cable with multiple strength members:
Step 1: Trim the strength member(s) on one side of the ribbon ush with the end of the strain-relief bracket
as shown in Figure 7A.
Step 2: Cut the remaining strength members ush with the edge of the cable sheath.
Step 3: With the strength members behind the bracket, install a washer and a nut on the restraint cap
threaded stud as shown in Figure 7B.
Step 4: Conrm ribbons are clear of the strength members. Tighten nut securely.
Step 5: Wrap vinyl tape around the restraint cap and the hose clamp to prevent damage to the ber.
Step 6: Repeat for the other end of cable sheath, when applicable.

4.6 Route Distribution Fibers
NOTE: Installation is illustrated with the Central Oce (CO) cable on the left side of the terminal and the drop
bers on the right side of the terminal. A separate end cap replacement kit is required to install drop
cable into the left side of the terminal. Contact your customer service representative to purchase the kit, if
required for your application.
Step 1: Determine from which end of the terminal the drop cables will exit.
Step 2: Separate the distribution bers from the other bers.
• In ribbon applications, separate the ribbon(s) to be spliced to the ribbon fan-out assembly from
the ribbons that will be expressed or spliced to single-ber pigtails.
• In loose-tube applications, separate the buer tube to be spliced to pigtails from the buer
tubes that will be expressed through the terminal.
Step 3: Loop unused express ribbon/tube(s) in the slack storage area as shown in Figure 11 and secure in the
routing clips.
