# Fiber Optic SC/APC Cable: High-Performance Connectivity Solution

## Introduction to SC/APC Cables

Fiber optic SC/APC cables represent a crucial component in modern telecommunications and networking infrastructure. These specialized cables combine the reliable SC connector with the angled physical contact (APC) polish, offering superior performance in various applications where signal integrity is paramount.

## Key Features of SC/APC Cables

The SC/APC cable design incorporates several important features that make it stand out in fiber optic connectivity:

– Angled Physical Contact (APC) polish reduces back reflection
– Standard SC connector form factor for easy installation
– Superior optical performance compared to flat-polished connectors
– Available in single-mode and multimode variants
– Durable construction for long-term reliability

## Technical Specifications

SC/APC cables typically offer the following technical specifications:

Parameter | Value
Insertion Loss | ≤0.3 dB
Return Loss | ≥60 dB
Operating Temperature | -40°C to +85°C
Connector Type | SC/APC
Fiber Type | Single-mode (typically)

## Applications of SC/APC Cables
