Pullable Bullet SC/APC Armored Fiber Patch Cord

Pre-terminated, Pullable Solution for FTTH & MDU Deployments

Overview

The Pullable Bullet SC/APC Armored Fiber Patch Cord represents a breakthrough in fiber-to-the-home (FTTH) and multi-dwelling unit (MDU) installations. Designed to eliminate the complexity of field termination, this pre-connectorized assembly features a patented Bullet SC/APC connector with an integrated pulling eye, allowing installers to pull the cable directly through conduits, microducts, and risers without risking damage to the connector or fiber.

The pullable bullet SC/APC armored cable is a rugged fiber optic patch cord designed for outdoor installation and harsh environments. The armored structure protects the fiber from tension, crushing, and rodent damage, making it ideal for FTTH deployment, telecom networks, and long-distance optical connections.

Key Features

1. Integrated Pulling Eye for Effortless Installation
The Bullet SC/APC connector features a robust stainless steel pulling eye with a tensile strength of 150N-200N. This allows the connector to be pulled through conduits with an inner diameter as small as 6mm, eliminating the need for splicing or field termination. A protective cap guides the cable smoothly through bends and tight spaces.

2. Stainless Steel Armored Protection
Unlike standard patch cords, this cable incorporates a flexible stainless steel spiral tube (SUS204) between the tight buffer and the outer sheath -1. This micro-armor provides:

• Rodent/Bite Protection: Prevents network outages caused by animals.

• Crush Resistance: withstands up to 1000N/100mm short-term crush load.

• Flexibility: Maintains a tight bend radius while offering steel-like durability.

3. Bend-Insensitive Fiber Performance
Utilizing G.657A2 (or G.657B3) bend-insensitive single-mode fiber, the cable ensures minimal signal loss even in tight corners common in residential and MDU installations. It remains fully compatible with standard G.652.D fiber networks .

4. High-Grade Optical Specifications
Engineered for long-distance, high-bandwidth applications, the cord meets stringent optical standards:

• Insertion Loss: ≤ 0.3dB (IEC Grade C1) .

• Return Loss: ≥ 60dB (APC polish), ensuring minimal back-reflection for video and high-speed data services.

5. Durable & Weather-Resistant Jacket
Available with LSZH (Low Smoke Zero Halogen) or TPU outer sheaths, the cable is UV-resistant and suitable for both indoor and outdoor use. The black TPU version offers enhanced protection against harsh weather and chemical exposure.

6. Simplified Polarity & Termination
The SC/APC connectors feature a green housing standard for angled physical contact, ensuring correct polarity and preventing damage to non-angled interfaces. The “Bullet” design snaps securely into place after pulling.

Technical Specifications

Construction Details

The robust construction of this patch cord ensures longevity in the field:

1. Tight Buffer: 0.6mm or 0.9mm (PVC/LSZH) protects the primary coating.

2. Armored Layer: Stainless steel spiral tube (1.4-1.5mm) for anti-crush and anti-rodent protection.

3. Strength Members: High tensile strength Aramid yarn for pull resistance.

4. Outer Sheath: LSZH or TPU, resistant to UV and weather.

Applications

Pullable armored cables are a specialized type of fiber patch cord used for outdoor installations, telecom infrastructure, and FTTH access networks where high mechanical strength is required.

• FTTH (Fiber to the Home): Ideal for last-mile drops from distribution boxes to ONT/ONU in apartments and houses.

• MDU (Multi-Dwelling Units): Easily pull cables through pre-existing conduits and risers between floors.

• Telecom Infrastructure: Connecting FAP boxes, FTBs, and FDBs in access networks.

• Outdoor/Industrial: TPU-jacketed versions are perfect for environments exposed to moisture, oil, or extreme temperatures.
