 1. What is Multi-Core Fiber?

 The Evolution of Optical Fiber

Traditional single-core fibers (SMF) have been the backbone of global internet infrastructure for decades. However, they face limitations:
 Capacity crunch (Shannon Limit)
 High power consumption
 Physical space constraints

Multi-Core Fiber (MCF) solves these issues by embedding multiple independent cores (typically 4-19 cores) within a single fiber cladding.

 How MCF Works

• Spatial Multiplexing: Each core transmits data independently, multiplying capacity.

• Reduced Crosstalk: Advanced designs minimize interference between cores.

• Compact Footprint: One MCF cable replaces multiple SMF cables.

 Types of MCF

1. Homogeneous MCF (Identical cores, simple manufacturing)

2. Heterogeneous MCF (Custom cores for specific wavelengths)

3. Few-Mode MCF (Supports multiple modes per core)
