Fiber Optic Fast Connector | Field Installable for FTTH Networks

Introduction

Opelink manufactures high-performance fiber optic fast connectors, enabling quick and reliable field termination of optical fibers without specialized tools or epoxy. With 13+ years of experience in FTTH solutions, we provide fast connectors that help network installers reduce deployment time and costs.

A fiber optic fast connector (also called a field-installable connector or quick connector) is a pre-polished, mechanical splice-on connector that can be installed in the field in approximately 2 minutes. Unlike traditional epoxy-and-polish connectors that require curing time and polishing equipment, fast connectors use precision mechanical alignment to achieve low-loss connections instantly.

Opelink fast connectors are available in SC and LC types for both 250μm bare fiber and 900μm tight-buffered cable. Our connectors feature insertion loss of less than 0.3dB and meet Telcordia GR-326 standards for reliability. They are the ideal solution for FTTH installations, emergency repairs, and situations where bringing fibers to a patch panel is impractical.

Fast Connector Types

Opelink offers fast connectors for various fiber types and applications:

1. SC Fast Connector
The most popular type for FTTH deployments. Push-pull coupling, 2.5mm ferrule. Available for 250μm bare fiber and 900μm cable. UPC and APC polish options.

2. LC Fast Connector
Compact design for high-density applications. Latch coupling, 1.25mm ferrule. Ideal for indoor installations and data center applications. Available for 250μm and 900μm fiber.

3. Open Flow Type
Features an open fiber path for easy fiber insertion and visibility during installation. Suitable for experienced installers who prefer visual confirmation.

4. Pre-cast Type
Features a pre-positioned fiber stub that aligns with the field fiber. Easier for less experienced installers. Provides consistent results with minimal training.

5. FTTH Drop Cable Connector
Designed specifically for figure-8 or flat drop cables used in FTTH. Accommodates the strength member and jacket of drop cables.

Installation Process

Installing an Opelink fast connector takes approximately 2 minutes:

Step 1: Strip the fiber using a precision fiber stripper. Remove 30-40mm of outer jacket and 8-10mm of coating to expose the bare fiber.
Step 2: Clean the bare fiber with alcohol wipes to remove any debris or coating residue.
Step 3: Cleave the fiber using a precision cleaver. The cleave length depends on the connector type (typically 8-12mm).
Step 4: Insert the cleaved fiber into the fast connector until it stops. The fiber will align with the pre-polished stub inside.
Step 5: Lock the fiber in place using the built-in mechanical clamp or cam mechanism. This secures the fiber and maintains alignment.
Step 6: Verify the connection with a visual fault locator or power meter. Check for proper insertion loss.
No epoxy, no curing time, no polishing required!

Applications

• MDU Installations: Multi-dwelling unit fiber distribution

FAQ

Q1: What is the difference between fast connectors and traditional epoxy connectors?

A: Fast connectors are pre-polished and use mechanical alignment, allowing installation in ~2 minutes without epoxy or polishing. Traditional connectors require epoxy application, curing time (typically 30+ minutes), and hand polishing with specialized equipment. Fast connectors are ideal for field installation; epoxy connectors are better for factory termination.

Q2: How reliable are fast connectors compared to fusion splices?

A: High-quality fast connectors like Opelink's provide insertion loss of <0.3dB, comparable to mechanical splices. While fusion splices typically have lower loss (<0.1dB), fast connectors offer significant time savings and don't require expensive fusion splicers. For most FTTH applications, fast connectors provide adequate performance with much faster installation.

Q3: Can fast connectors be removed and reused?

A: No, fast connectors are designed for one-time installation. Once the fiber is locked in place and the connector is closed, it cannot be reopened without damaging the connector. If a mistake is made during installation, the connector must be replaced.

Q4: What tools do I need to install fast connectors?

A: Basic tools required: fiber stripper, precision cleaver, cleaning materials (alcohol wipes), and visual fault locator (recommended). No epoxy, curing oven, or polishing equipment needed. A fiber preparation kit typically costs under $200, compared to thousands for a fusion splicer.

Q5: Are fast connectors suitable for outdoor installations?

A: Opelink fast connectors are rated for -40°C to +85°C operating temperature, making them suitable for outdoor FTTH installations. However, they should be protected inside enclosures or weatherproof boxes. For direct outdoor exposure, additional sealing or armored connectors may be required.
