Fiber optic cable is often damaged by gnawing rodents. Such damage can impact the long-term reliability of outdoor cables and depends upon the specific species of rodent (rats, birds, squirrels) and geographic location (mountainous, hills). However,anti-rodent fiber optic cable offers high tensile strength and crush resistance to prevent rodents and other animals from being bitten.

Fiber optic cable is often damaged by gnawing rodents. Such damage can impact the long-term
reliability of outdoor cables and depends upon the specific species of rodent (rats, birds, squirrels) and
geographic location (mountainous, hills). However,anti-rodent fiber optic cable offers high tensile
strength and crush resistance to prevent rodents and other animals from being bitten.
What is Anti-Rodent Fiber Optic Cable?
The anti-rodent fiber optic cable is suitable for use in many places with lots of rats. The cable is
made of special material and has a special structure. Its special material prevents communication
interruption caused by fiber damage in the cable. In different installation environments, the
structure of the anti-rat optical cable will also be different. For example, optical cables are laid in
pipes, usually with steel tape or (and) Nylon sheaths to prevent rodents. If the optical cable is laid

overhead, glass yarn or FRP armor is usually used and the structure is mostly non-metallic.This
article will focus on duct-type anti-rodent fiber optic cable.
Cable Types
Generally, the types of anti-rodent cable are GYXTW53, GYFHTY63, and GYTA53.
1. GYXTW53 armored cable uses 250μm fiber positioned in a loose tube made of a high-modulus
plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes
sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of the core as
a metallic strength member. Tubes (and fillers) are stranded around the strength member into a
compact and circular cable core. the double-coated plastic strip (PSP) is applied around the cable
core. which is filled with the filling compound to protect it from water ingress. Then the cable core
is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath,
the cable is completed with a PE outer sheath.

2. GYFHTY63 stranded loose tube nonmetallic strength member armored and double sheathed
cable construction is that 250um fibers are positioned in a loose tube which is made of high
modulus plastic and filled with a water-resistant filling compound; A fiber reinforced plastic (FRP),
sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of
core as a non-metallic strength member; Tubes are stranded around the strength member into a
compact and circular cable core; Water blocking yarn and water blocking tape protect cable core
from water ingress and covered with a polyethylene (PE) inner sheath; After fiber glass fiber yarns
are longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
3. GYTA53 stranded loose tube double armored and double sheathed cable construction is that
250um fibers are positioned in a loose tube which is made of high modulus plastic and filled with
a water-resistant filling compound; A steel wire, sometimes sheathed with polyethylene (PE) for

cable with high fiber count, locates in the center of core as a metallic strength member; Tubes are
stranded around the strength member into a compact and circular cable core; The APL (Aluminum
Tape) is longitudinally applied over the cable core which is filled with the filling compound to
protect it from water ingress and then the cable core is covered with a polyethylene (PE) inner
sheath; After the PSP (Steel Tape) is longitudinally applied over the inner sheath, the cable is
completed with a polyethylene (PE) outer sheath.
Features and Benefits
 High tensile strength, rat-bite prevention, temperature performance
 Loose tube filled with special ointment for key fiber protection
 Water-blocking structure to ensure good water-blocking and moisture resistance, corrosion
resistance,UV resistant
 Small diameter, lightweight, flexible, and easy installation
Applications
Anti-rodent cables are used in outdoor, direct buried, duct, overhead, pipeline installations, core
networks, metropolitan area networks (MAN), access networks, lightning and anti-electric field,
long-distance communication, local trunk line,CATV, etc.
