Ethernet Standards of Optical Network

Introduction
Ethernet is a widely used networking technology that enables
communication between devices within a Local Area Network (LAN).
Optical Ethernet utilizes fiber optic cables instead of traditional copper
cables, providing high-speed and long-distance data transmission. The IEEE
802.3 standard defines various Ethernet specifications, including fiber-based
standards.

Importance of Optical Ethernet


- Provides higher bandwidth compared to copper Ethernet.
- Supports long-distance communication with minimal signal degradation.
- More reliable and immune to electromagnetic interference (EMI).
- Commonly used in high-speed data centers, telecommunications, and
enterprise networking.

IEEE 802.3 Ethernet Standards


The IEEE 802.3 standard classifies Ethernet networks based on speed:
1. **Standard Ethernet** – 10 Mbps
2. **Fast Ethernet** – 100 Mbps
3. **Gigabit Ethernet** – 1 Gbps and above

These standards define the physical and data link layer protocols.

10-Gigabit Ethernet and Beyond


- **Standards:** 10GBaseSR, 10GBaseLR, 10GBaseER
- **IEEE Specification:** 802.3ae
- **Cable Type:** Optical fiber
- **Maximum Distance:**
- Up to 40 km (single-mode fiber)
- Used in high-speed data centers and backbone networks
Advantages of Optical Ethernet
