• In general this cable will handle similarly to coaxial cable, and similar installation techniques apply. All cables
are individually serialized, be sure to write down the cable serial number for future reference.
• The terminated fiber ends (the broken out fibers plus connectors) however are fragile, and these must be
protected during the installation process.
• Leave the protective tube and sock around the fiber tails and connectors in place during hoisting and
securing the cable. Remove this only just prior to making the final connections to the Junction box.
• DO NOT BEND THE FIBER ENDS (in the furcation tubes) TIGHTER THAN 1.2" (30mm) BEND RADIUS ELSE THERE
IS A RISK OF BREAKING THE GLASS FIBERS.
• Be sure that the lace up ends and fiber connectors are not damaged by attachment of a hoisting grip or
during the hoisting process. Attach a hoisting grip on the jacketed cable no less than 6" below the fiber breakout
point. If a hoisting grip is not easily attached, use a simple line attached below the fiber break-out point (i.e. at
the cable outer jacket). Prevent the fiber tails (in protective tube) at the cable end from undue movement during
hoisting by securing the protective tube (with outer sock) to the hoisting line.
• During hoisting ensure that there is a free path and that the cable, and especially the fiber ends, will not be
snagged on tower members or other obstacles.
• Installation temperature range is -22F to 158F
(-30C to +70C).
• Minimum cable bend radii can be found in this
document or on-line.
• Maximum cable tensile load can be found in this
document or on-line.

CommScope Lace-Up Hoisting Grip 19256B-C
required for 406 and 806 installations.
•
CommScope Lace-Up Hoisting Grip 29961-C
required for 1206 installations.
• Maximum hanger spacing 3ft (0.9m) - 4ft (1.2m)
Hybrid Fiber Cables weigh more than traditional
coaxial cables. Be sure to follow proper hoisting
and attachment procedures.
