The blog post will discuss these benefits in greater detail to help you decide if a 90-degree fiber optic connector is the right choice for your network setup.

1) What is a 90 Degree Fiber Optic Connector?

A 90-degree fiber optic connector is a specialized connector used in networking setups. It allows the fiber optic cable to be connected at a right angle to the equipment, providing flexibility and ease of installation. This type of connector is beneficial in tight spaces where traditional straight connectors may not fit or where a tight bend radius may compromise the integrity of the fiber optic cable. 90-degree fiber optic connectors are available in various types, including LC, SC, and ST.

2) Advantages of Using a 90-degree Fiber Optic Connector

1. Space-saving: A 90-degree fiber optic connector is perfect for cramped or tight spaces, allowing cables to be routed at a right angle without adding extra length or bulk to the network setup.

2. Improved Signal Quality: Using a 90-degree fiber optic connector can eliminate bending or kinking in cables that could lead to signal loss or damage to the fiber optic cable.

3. Increased Durability: 90-degree fiber optic connectors are designed to provide extra protection to cables and prevent wear and tear on connectors, leading to a long lifespan and reduced maintenance costs.

4. Ease of Installation: The compact size and flexibility of 90-degree fiber optic connectors make them easy to install in tight spaces, saving time and effort in setting up your network.

5. Compatibility with Different Cable Types: 90-degree fiber optic connectors are compatible with single-mode and multi-mode fiber optic cables, making them a versatile choice for any network setup.

3) Types of 90 Degree Fiber Optic Connectors Available

Several types of 90-degree fiber optic connectors are available on the market today, including SC, LC, and ST. Each class has unique features and benefits, such as ease of installation, higher bandwidth capabilities, and increased durability. Choosing the correct connector for your specific network setup is essential to ensure optimal performance and reliability. Consult with a fiber optic expert or supplier to determine which type of 90-degree connector is best for your needs.

4) How to Choose the Right 90-degree Fiber Optic Connector 

Choosing the suitable 90-degree fiber optic connector requires considering various factors to ensure compatibility and optimal performance for your specific application. Here’s a step-by-step guide to help you make the right choice:

  • Understand the Connector Types: Fiber optic connectors come in various types, such as SC, LC, ST, FC, etc. Each class has specific characteristics and applications. Please familiarize yourself with the different connector types and their features.
  • Determine the Fiber Type: Identify the type of fiber optic cable you use, single-mode or multi-mode. Your connector should match the fiber type to ensure efficient light transmission.
  • Application and Environment: Consider the environment where the connector will be deployed. Standard connectors might suffice if it’s for indoor use within controlled conditions. However, for harsh environments or outdoor applications, you may need connectors with additional protection, such as armored connectors or weather-resistant options.
  • Connector Polish Type: The most common connector Polish types are PC (Physical Contact) and APC (Angled Physical Contact). PC connectors have a flat end-face, while APC connectors have an angled end-face. APC connectors typically offer lower insertion loss and back reflection, making them suitable for specific applications like FTTx (Fiber to the x) networks.
  • Connector Endface Quality: Ensure the connector’s end face has high-quality polishing to minimize signal loss and maintain a low reflectance level. Dust, dirt, or scratches on the end face can significantly impact performance.
  • Connector Compatibility: Verify that the connector is compatible with your equipment. Check the connector type your devices require, such as switches, transceivers, or patch panels.
  • Ease of Installation: Some connectors might be easier to install than others, especially in tight spaces or challenging installation environments. Consider ease of installation and the availability of any necessary tools when deciding.
  • Connector Performance Specifications: Check the connector’s technical specifications, including insertion loss, return loss, and operating wavelength. The connector should meet or exceed the requirements of your application to ensure optimal signal performance.
  • Consider Future Expansion: If you anticipate future expansion or upgrades, consider connectors that will accommodate your potential growth needs without requiring significant changes to the existing infrastructure.
  • Budget and Supplier Reputation: Finally, consider your budget for the project and ensure you’re buying from a reputable supplier known for providing high-quality products.
  • In summary, choosing the suitable 90-degree fiber optic connector involves:

  • Understanding the connector types.
  • Matching the connector to your fiber type.
  • Considering the application and environment.
  • Evaluating end face quality and performance specifications.
  • Factoring in installation ease and future expansion plans.

Taking the time to assess these factors carefully will help you make an informed decision that best meets your needs.

5) Installing and Maintaining Your 90 Degree Fiber Optic Connector

Installing and maintaining a 90-degree fiber optic connector requires precision and care to ensure optimal performance and reliability. Here’s a step-by-step guide for both installation and maintenance:

Installing a 90-degree Fiber Optic Connector:

Prepare the Work Area:

· Ensure working in a clean and dust-free environment.

· Use safety gear, such as safety glasses and gloves.

Inspect the Connector:

· Check the connector for any visible damage or contamination.

· Verify that the connector matches your application’s fiber and polish types.

Clean the Connector Endface:

· If the connector end face is not clean, use lint-free wipes and a suitable fiber optic cleaning solution to clean it gently. Avoid touching the cleaned end face.

Prepare the Fiber Cable:

· Strip the fiber cable to expose the fiber core and cladding.

· Follow the manufacturer’s instructions for your specific cable and connector type.

Insert the Fiber into the Connector:

· Carefully insert the exposed fiber end into the connector ferrule until it reaches the stop.

· Make sure the fiber is aligned correctly and centered within the ferrule.

Crimp or Apply Adhesive:

· Depending on the connector type, follow the appropriate method to secure the fiber in the connector.

· For some connectors, crimping is necessary, while others use adhesive to fix the fiber.

Cure or Set the Connector:

· If adhesive is used, follow the curing process recommended by the manufacturer.

· If crimping is required, ensure the connector is securely attached to the fiber cable.

Perform a Visual Inspection:

· Examine the connector for any signs of damage, misalignment, or contamination.

· Check that the connector’s end face is clean and properly aligned.

Maintaining a 90-degree Fiber Optic Connector:

Regular Inspection:

· Routinely inspect the connectors for any signs of damage or contamination.

· Consider more frequent inspections if the connectors are in an exposed or harsh environment.


· Clean the connector end face when necessary using lint-free wipes and a fiber optic cleaning solution.

· Avoid touching the end face with fingers or any other objects.

Protective Dust Caps:

· When connectors are not in use, keep them covered with protective dust caps to prevent contamination.

Frequent Reconnection:

· Minimize frequent reconnections, as each connection introduces the risk of contamination and potential damage.

Use Proper Tools:

· When making connections or disconnections, use appropriate tools to avoid applying excessive force or stress on the connectors.
