Buying Guide – How to Choose the Best Fiber Optic Sc Connectors

Selecting the right SC connector involves understanding your network type and installation requirements. This guide outlines the key factors to consider before making a purchase.

Connector Type: APC vs UPC

APC connectors feature an angled polish that reduces back reflection making them ideal for high speed singlemode networks and video signals. UPC connectors have a flat polish and are generally used for lower reflection applications like standard data networks.

Choose APC for singlemode and CATV to minimize signal loss and UPC for standard multimode or general data use cases.

Insertion Loss and Return Loss

Insertion loss measures how much signal power is lost when passing through the connector while return loss measures how much signal is reflected back. Lower insertion loss and higher return loss indicate better performance.

Look for connectors with insertion loss below 0.3 dB and return loss above 45 dB for reliable network performance.

Installation Method

Fast connectors allow you to terminate fiber quickly without polishing or glue. This is essential for field work where speed and simplicity are required over complex laboratory conditions.

Select connectors that match your available tools and expertise level to ensure successful termination.

Fiber Core Size

Singlemode fibers have a core size of 9 microns while multimode fibers are 50 or 62.5 microns. Using the wrong connector for the fiber type will result in high signal loss or connection failure.

Always verify the fiber specification before buying to ensure compatibility.

Material and Durability

Connectors made from high quality materials like ceramic and durable polymers withstand environmental stress and mechanical strain. This is crucial for outdoor or harsh climate applications.

Check for temperature ratings and material specifications to ensure longevity.

Pack Size and Quantity

Products come in various pack sizes ranging from 10 to 100 units. Buying in bulk reduces the cost per unit and ensures you have spares for future repairs.

Choose a pack size that matches the scale of your deployment project.

Ease of Use

Features like preset blocks and alignment guides make installation easier and more consistent. This reduces the risk of user error during termination.

Prioritize connectors with clear installation instructions and user friendly designs.

How to Use and Care for Your Fiber Optic Sc Connectors

Begin by cleaning the fiber end face using a lint free wipe and alcohol to remove dust or oils before inserting it into the connector.

Use the provided cleaver to cut the fiber at the exact length specified in the connector manual to ensure proper alignment and signal transmission.

Store unused connectors in their protective caps or a clean dry case to prevent dust accumulation on the critical optical surfaces.
