# Complete Introduction to GJYXCH Self-Supporting Butterfly Drop Optical Cable

## I. Model Letter Explanation (National Standard YD/T 1997.1-2014)

**GJYXCH = Metal Suspension Self-Supporting, Metal Wire Reinforced, Low Smoke Halogen-Free Butterfly Drop Optical Cable**

- GJ: Access Network Butterfly Drop Optical Cable (Drop Cable)

- Y: **Metal Wire** (Both sides of the fiber core reinforcement are phosphated steel wire)

- X: Figure-8 Self-Supporting Structure (One-piece Molded Suspension)

- C: Self-Supporting Suspension Unit

- H: **LSZH Low Smoke Halogen-Free Flame Retardant Outer Sheath**

## II. Internal Structure (Figure-8 Integrated from Top to Bottom)

1. **Upper Suspension Unit**: Coarse phosphated steel wire suspension (main load-bearing, no additional steel strand required for overhead applications)

2. **Lower Butterfly-Shaped Cable Core Unit**

- Center: Single-mode optical fiber (mainstream G.657A2 bend-resistant fiber, 1/2/4 cores)

- Two parallel **0.4mm phosphated steel wires** on the left and right (fiber protection for tensile and compressive strength)

- Integrated extruded black LSZH low-smoke halogen-free sheath, with pre-fabricated easy-tear stripping grooves on both sides

3. Overall Shape: Flat figure-8 shape, standard size approximately 2.0mm × 5.2mm, weight approximately 19kg/km

## III. Core Product Features

1. **Integrated Suspension Wire, Purely Self-Supporting Aerial Application** The top coarse steel wire bears the entire span tension, eliminating the need for additional steel strands for community poles and building-to-building overhead applications, resulting in low construction costs.

2. **Double Steel Wire Fiber Sheath, High Mechanical Strength**
Long-term tensile strength 800N, short-term tensile strength 2000N; resistant to wind and tensile stress, and heavy object compression, suitable for long-term outdoor use.

3. **Low Smoke Halogen-Free Flame Retardant LSZH Sheath**
Low smoke during combustion, no toxic halogen gases, meets fire safety regulations even when entering buildings or building shafts outdoors; black sheath is UV resistant and weather resistant from -60℃ to +70℃.

4. **G.657A2 Micro-Bend Fiber**
Minimally bent, no attenuation; less prone to light loss when winding through corridors, corners, or entering buildings through conduits.

5. **Built-in Stripping Groove, Fast Installation**
Fiber can be removed by hand by tearing open the sheath; no professional stripping tools required; quick cold splicing/heat fusion.

6. **Lower Cost Due to Metal Structure**
Compared to the non-metallic GJYXFCH model, the steel wire reinforcement is cheaper and preferred for scenarios without strong electromagnetic interference.

## IV. Standard Mechanical Parameters (1-Core Standard Model)

## V. Applicable Scenarios (FTTH Fiber to the Home Dedicated)

### 1. Outdoor Aerial (Core Application)

- Community Optical Distribution Box → Building Exterior Wall Aerial, Inter-Building Cabling

- Rural and Township Pole-to-Home, Short-Span Self-Supported Laying

### 2. Outdoor to Indoor Integrated Cabling

Outdoor aerial cabling directly through building shafts and low-voltage cable shafts to the home; LSZH sheath meets indoor fire protection requirements.

### 3. Supporting Scenarios

Cyber ​​broadband access for operators, monitoring point introduction, and end-point introduction for government and enterprise private lines.

### Not Applicable Scenarios

1. Near substations, high-voltage cables, and mountainous areas prone to lightning strikes (steel wire is prone to lightning attraction; use **GJYXFCH Non-Metallic Model** instead)

2. Long-Distance Aerial Backbone (For home introduction only; backbone uses ADSS/aerial duct optical cable)

## VI. Comparison of Easily Confusing Models

### 1. GJYXCH vs GJYXFCH

- GJYXCH: **Steel wire reinforced**, inexpensive, high tensile strength; Disadvantage: Conductive, prohibited in lightning/high-voltage areas

- GJYXFCH: **FRP non-metallic reinforced**, lightning protection without electromagnetic interference; more expensive

### 2. GJYXCH vs GJXH (Ordinary Indoor Drop Cable)

- GJYXCH: With top suspension wire, can be used for outdoor overhead wiring, LSZH sheath

- GJXH: Without suspension wire, only for indoor conduit/wall wiring, cannot be used for outdoor overhead wiring

### 3. GJYXCH vs GJYXDCH

- GJYXCH: Single independent optical fiber

- GJYXDCH: Fiber optic cable with ribbon, used in multi-core centralized splicing scenarios

## VII. Model Labeling Example

`GJYXCH-1B6a2`

- GJYXCH: Metal Suspension Wire Self-Supporting Low-Smoke Halogen-Free Butterfly-Shaped Drop Cable

- 1:1 Core Fiber Optic Cable

- B6a2: G.657A2 Bending-Resistant Single-Mode Fiber Optic Cable (Standard Fiber for Home Delivery)

## VIII. Construction Precautions

1. The overhead span should generally be ≤80 meters. In windy areas, shorten the span and use dedicated optical cable hooks to secure the suspension wire;

2. The tensile force must not exceed 2000N for short periods to avoid damaging the optical fiber due to steel wire tension;

3. In scenarios with frequent lightning strikes or high-voltage lines on the same pole, replace with non-metallic GJYXFCH;

4. For installation in building shafts, H-type LSZH sheathed cables must be used; ordinary PVC drop cables are prohibited.
