Rodents can cause severe damage to fiber optic cable infrastructure by chewing through cable sheaths and core components, and causing service outages at high costs. To avoid this risk, rodent-resistant fiber optic cables are equipped with special guard layers and materials stated to keep rodents away.
In this publication, we are going to focus on the groups, types, benefits, and use of rodent-resistant fiber optic cables as a way of informing you to select the right one for your networking environment.
Rodent-Resistant Fiber Optic Cables are type of cable with rodent-inhibiting properties that reduce the chances of destructive behavior by rodents toward the cable sheath. Through this, they are able to achieve:
Metal or non-metallic armor (e.g., steel tape, FRP, or glass yarn).
Hard outer sheaths, such as nylon.
Rodent-repellent materials in some cases.
These rodent resistant fiber optic cables offer increased reliability, operational readiness, and permanent line interruptions curtail.
Leveraging Cable Network Features Eliminates Ruggedness Challenges of Fiber Optic Cable Harnessing Installation Process.
✅High Mechanical Strength:
Resist crushing, abrasion, and tension.
✅Water Blocking:
Inclusion of either gel or dry water-blocking materials reduces the amount of moisture entering the cable.
✅Corrosion Resistance:
APL or stainless steel (metal armor) prolongs period of implementation.
✅Temperature Tolerance:
Conformance to –40°C up to +70°C environment conditions.
✅Installation Flexibility:
Agility for deployment of efficient intertwined strip armors (for instance, thin steel wire).
These cables cover the metal armor layers that ensure a physical barrier against rats' bites. Suited for direct beneath the ground or duct types, especially in risky outdoor conditions.
Structure:
Straight tube design with the blocking water gel.
Inner layer: APL made of corrugated aluminum tape + PE sheath.
Outer layer: PSP made of corrugated steel tape + PE outer sheath.
Features:
Superb resistance to target pests.
The most effective barrier against moisture and pressure.
Structure: Strip of steel armor with core and PE sheath.
Note: Less expensive and attains rust over a period
Advantages:
Rustproof and highly durable.
Strong protection against rodents.
Disadvantages:
Bigger and heavier.
More cumbersome installation and expensive.
Structure:
A structure that uses fine steel wires (0.45–1.6mm) as armor materials and is mostly combined with steel tape.
Advantages:
Greater flexibility and resistance to rodent.
Lightweight and a simple installation.
Developed and manufactured for extreme EMI emission reduction and/or lightweight application sectors.
Structure:
Loose tubes carrying blocks to block water.
The strongest element according to fiber-reinforced plastic.
Glass filament carries + layer of sub-Pe sheath.
Advantages:
Elderly resistant, oxidation free, production of magnetic interference free, and eating of rats.
Mechanism: Rodents avoid the harmful splinters of the glass fibers when they chew it.
Pros: Could be useful in overhead/rooftop deployment.
Cons: There may be unwarranted injuries during this; it would cost slightly more.
Feature: The outer sheath is 8 nylon (PA) high-hardness stuff.
Use Case: Indoor local telephone exchanges and light outdoor applications.
Technology: No gel filling – using textile or string for protection from moisture.
Application: Clean environment for maintaining and servicing too much dirt or dust like data centers.
Technology | Example Cables | Benefits | Limitations |
Steel Tape Armor | GYTS, GYTA53 | Strong, cost-effective | Prone to corrosion |
Stainless Steel Tape | GYTA43 | Durable, high hardness | Heavy, expensive |
Fine Steel Wire Armor | GYXTS | Flexible, lightweight | May require additional shielding |
FRP / Glass Yarn | GYFHTY63 | EMI-safe, non-metallic | Risk to installers |
Nylon Sheath | Custom Designs | Lightweight, great indoors | Less durable outdoors |
Chemical Repellents | Certain PE/PVC | Short-term anti rodent cable aid | Effectiveness fades with time |
Use Case | Recommended Cable |
High Rodent Activity | GYXTS (steel wire), GYTA43 (stainless) |
EMI Sensitive Zones | GYFHTY63 (FRP-based) |
Lightweight Requirement | GYQXT3S (thin wire armor) |
Indoor Cabling / Data Centers | Nylon-sheathed anti rodent fiber cable |
Outdoor Longevity | Double-armored or non-metallic designs |
✅Physical Protection
Bring armored or steel wire, steel tape, or FRP armor fiber optic designs into play.
Grain fiber optic cables in conduits or ducts in areas that are prone to rodent infestation by the greatest degree possible.
✅Smart Route Planning
Go away from the area of known rats' nests.
Opt for a rodent drop cable or install aerial cables where practical.
✅Material Selection
Opt for bite-proof cables with thick jackets for best results (PE, Nylon are perfect choices).
Defence use of rodent proof fiber optic cable for underground and rural applications.
✅Regular Inspection & Maintenance
Regular monitoring helps in spotting immediate concerns.
Use repellents for one-time control, but it is much more effective to use physical barriers.
IEC 60794 – Meeting the tests for optical fiber cable (including resistance to the properties of rodent).
TIA-568-C.3 – In the United States, the fiber cabling standards include warranty requirements.
YD/T 901 – relates to a Chinese outdoor fiber cable standard.
