Weather Resistance
•Drop cables can withstand various weather conditions, including rain, snow, and extreme temperatures.
•The protective sheaths and waterproof layers prevent moisture penetration, ensuring reliable performance in harsh outdoor environments.
Flexibility and Bending Performance
•Drop cables offer excellent flexibility and bending performance, allowing for easy routing and installation in outdoor settings.
• Their small outer diameter and light weight make them highly adaptable to different installation scenarios.
High Tensile Strength
•Drop cables possess high tensile strength, enabling them to withstand stretching and pulling forces during installation and aerial deployments.
•This makes them suitable for applications that require suspension or long-distance spans.
Enhanced Protection
•Drop cables incorporate reinforced steel wires and FRP/KFRP reinforcement materials for added protection against compression, flattening forces and external impacts.
•This ensures the cables can withstand physical stress and maintain signal integrity.
Safety Considerations
•Drop cables prioritize safety by utilizing low-smoke and halogen-free flame-retardant materials.
•This reduces the risk of toxic fumes and fire hazards, meeting flame-retardant performance requirements for both indoor and outdoor usage.
Easy Installation and Cost-Effectiveness
• Drop cables are designed for easy installation, reducing labor and time requirements.
•Their cost-effective nature makes them an economical choice for extending communication networks to outdoor areas.
Types of Drop Cable
Toneable Fiber Optic Drop Cable:
Toneable Drop Cable contains a metal element that runs parallel to the optical fiber. Typically made of copper or steel wire, this element allows the drop cable to be traced or located with a metal detector or tone generator. This makes toneable drop cable the ideal choice for burial application.
Nontoneable Fiber Optic Drop Cable:
Nontoneable Drop Cable does not contain metal tracing wire, which can make it more flexible. Typically, nontoneable drop cable would be used in aerial applications.
Tight-Buffered 900 μm Fiber Optic Drop Cable:
Tight buffered fiber optic drop cables are a popular choice when installing mechanical connectors to the NID (Network Interface Device) box. A NID box is simply a small, weather proof, enclosure typically made of plastic that houses the termination from the main network to the dwelling.
Loose-Tube 250 μm Fiber Optic Drop Cable:
Loose-Tube fiber optic drop cables contain a 250um fiber packaged with either a icky-pic gel or treated aramid yarn for protection against water penetration. This is preferred cable when installers are doing fusion splicing at side of the house or at the fiber enclosure because its smaller and easier to store away.
Comparing Flat vs Round Drop Cable
|
Feature / Consideration |
Flat drop cable |
Round drop cable |
|
Profile |
Flat or “butterfly” shape with parallel strength members |
Cylindrical with strength members embedded alongside the core |
|
Fiber count |
Typically 1–12 fibers |
Usually 1–2 tight-buffered fibers |
|
Strength member |
Two dielectric members; self-supporting versions include an extra messenger wire |
Two FRP members; design may be more flexible for indoor runs |
|
Installation |
Suitable for self-supporting aerial spans, direct-buried or duct installations; easy to strip |
Ideal for outdoor-to-indoor transitions, building entry, micro-duct applications |
|
Tensile load |
Self-supporting versions support spans up to ~80 m; non-self-supporting need external support |
Suitable for shorter spans; emphasises durability rather than long aerial reach |
|
Typical use case |
FTTH customer drops, multi-tenant building risers, aerial installations |
Building entrance cables, indoor drop cables, network equipment jumpers |
Indoor Uses
Indoor optical cables mainly include 1F, 2F, and 4F, while Household optical cables should use 1F, and Enterprise users should use 2-4F optical drop cable design.
Household optical cables are divided into two types
Fiber-Reinforced plastic and steel wire reinforced. Considering lightning protection and strong current interference, the interior should use Fiber-Reinforced Plastic.
Laying of Fiber Optic Cables in Buildings
The horizontal wiring in buildings does not require high fiber optic cables. At the same time, the vertical wiring requires a specific tensile strength of fiber optic cables and flame-retardant requirements. Therefore, the tensile strength of the fiber optic cable must be considered.
Overhead Self-Supporting Wire Laying
The flat figure-8 self-supporting fiber optic cable adds steel wire suspension to the cable, which has stronger tensile strength and can be laid overhead. It is suitable for outdoor into indoor wiring environments.
Duct Wire Laying
Duct optical cables and flat figure-8 self-supporting fiber optic cables are indoor and outdoor integrated optical cables that can adapt to indoor and outdoor environments. They are suitable for FTTH drop cables from outside to indoors.
Installation Method of Drop Cable
》The installation crew flags existing utility lines, as a safety measure.
》A trench is cut from the ONT pedestal, hand vault, or enclosure. Depending on the climate, it's important to dig below the frost line in the soil.
》The Drop Cable is installed at the bottom of the trench. Burial applications usually call for Toneable Cable, so the drop cable can be located easily after installation.
》The technician will bring the drop cable to the side of the house or building to a enclosure often called a Network Device Enclosure (NID) box. If the cable drop cable is not preconnectorized, the technician will use a cable slitter to open the sheath of the cable, strip back components and splice a fiber optic connector to the field cable. If the ONT is located in the NID the drop cable is attached otherwise the connector is then plugged into a mating sleeve inside the NID and continues inside the building on different smaller cable until it reaches the ONT and is attached.
》Once the fiber is connected, the trench can be filled and covered. Slack drop cable is spooled within the enclosures or pedestals for future maintenance.
》A messenger wire, usually galvanized steel, is strung between the pole or strand wire to the side of the building. Prior to cable being hung slack loops are created at the beginning of 6-8 loops then after is attached to building structure with correct hardware additional slack loops of 6-8 loops are placed beneath the NID box before cable enters. Slack loops typically come in 8”-16” diameter brackets. These slack loops are important to minimize retraction on the drop cable as it begins to relax or stretch after installation. Eliminating recommended slack loops from your installation can result in fiber cable tightening in the NID box.
》The fiber optic drop cable is threaded through the support poles and messenger wire. As the cable is installed, it is typical to place snowshoe spools near the support poles to manage slack cable.
》The cable is connected at the ONT and at the onsite enclosure.
