Ftth Pre-embedded cold joint

FTTH pre-embedded SC cold joint connectors allow fast, reliable fiber termination in the field without fusion splicing, using a mechanical cold joint for stable optical performance.

Overview

FTTH pre-embedded SC cold joint connectors are designed for quick field assembly in fiber-to-the-home networks. They use a mechanical cold splice method, eliminating the need for fusion splicing, polishing, or glue. This makes them ideal for rapid deployment in FTTH, FTTX, and other fiber-optic network applications, including Wi-Fi, 3G/4G, and wired LAN systems .

Key Features

• Pre-embedded fiber structure: The fiber is pre-installed inside the connector, ensuring high installation quality and a high success rate .
• Mechanical cold joint: The connector aligns and secures the fiber using a V-groove or pressing structure, providing low insertion loss (typically around 0.3 dB) and high return loss .
• Fast installation: Assembly can be completed in under 90 seconds using simple tools, without requiring electrical or polishing equipment .
• Compatibility: Works with both 3mm round drop cables and 3x2mm flat cables, supporting SC UPC or SC APC types .
• Durability: Made from ABS or similar materials, these connectors operate reliably across a wide temperature range (-40°C to +85°C) and withstand harsh field conditions .

Installation Process

1. Strip the fiber cable jacket and clean the bare fiber.
2. Insert the fiber into the connector body.
3. Align the fiber using the V-groove or pressing mechanism.
4. Secure the fiber with the mechanical clip or boot.
5. Complete the assembly and verify optical performance using a fiber checker .

Advantages

• No fusion splicer required: Reduces cost and complexity in field deployments.
• Quick deployment: Ideal for large-scale FTTH installations.
• Reusable and low defect rate: The mechanical design allows removal and reassembly if needed .
• Direct connection to ONU: Can connect directly without additional optical sockets, reducing overall FTTH costs .

Applications

• Fiber patch panels and distribution frames
• FTTH subscriber connections
• Fiber-optic network equipment
• Cable television networks
• On-site patch cord assembly for FTTX deployments FTTH pre-embedded SC cold joint connectors provide a reliable, fast, and cost-effective solution for field fiber termination, combining mechanical precision with ease of installation, making them a popular choice for modern fiber-optic networks .
