3. ABSTRACT
Optical Ethernet is the physical layer of the Local Area
Network (LAN)communications protocol for sending data over
fiber-optic cable. It is used for connecting Internet servers and
switches inside equipment racks, within data centers, and
between metropolitan data centers. Today the most widely used
LAN data rate is 1 Gb/s, with increasing adoption of 10 Gb/s.
These rates are insufficient to support core networking
requirements, such as switching, routing, and aggregation in
large data centers, Internet exchanges, and service provider
peering points; and high-bandwidth applications, such as video
on demand and high-performance computing environments. To
support these applications, the IEEE 802.3ba Task Force is in
the process of standardizing a 100-Gb/s LAN data rate, which
is the subject of this article.

4. INTRODUCTION
 Optical Ethernet: combination of two technologies-
EHTERNET & OPTICS
 It combines the flexibility and simplicity of Ethernet with the
reliability and speed of optics.
 Optical Ethernet attributes – simplicity, speed, and reliability .
 It removes the bandwidth bottleneck between the LAN and the
WAN

5. WHAT IS OPTICAL ETHERNET
Optical ehternet :
 the IEEE has approved the 802.3ba Ethernet in the first
mile(EFM) standard
 The first mile is the network infrastructure that connects
business or residential subscribers to the customer of a
telecom carrier or a service provider

6. HOW OPTICAL ETHERNET WORKS
 Ethernet is a type of connection between computers that forms
the basis of most Local Area Networks (LAN).
 It also serves as one of the main methods for connecting a
computer or network to an Internet hub.
 Router in order to network several computers together.

7. TYPES OF ETHERNET

8. STANDARD ETHERNET
A standard Ethernet network can transmit data at a rate up
to 10 Megabits per second (10 Mbps).
Other LAN types include
 Token Ring
 Fast Ethernet
 Gigabit Ethernet
 10 Gigabit Ethernet
 Fiber Distributed Data Interface (FDDI)
 Asynchronous Transfer Mode (ATM)
 LocalTalk

9. IMPLEMENTATION STANDARD ETHERNET

10. FAST ETHERNET
The fast Ethernet is a type of Ethernet network that
can transfer data at a rate of 100 Mbps
using a twisted-pair cable or a fiber-optic cable.
The older 10 Mbps Ethernet is still used, but such
networks do not provide necessary bandwidth for
some network-based video applications.
Fast Ethernet is based on the proven CSMA/CD
Media Access Control (MAC) protocol, and uses
existing 10BaseT cabling.
Data can move from 10 Mbps to 100 Mbps without
any protocol translation or changes to the
application and networking software.

11. IMPLEMENTATION OF FAST
ETHERNET

12. GIGABIT ETHERNET
The Gigabit Ethernet is a type of Ethernet network
capable of transferring data at a rate of 1000 Mbps
based on a twisted-pair or fiber optic cable, and it
is very popular.
The type of twisted-pair cables that support
Gigabit Ethernet is Cat 5e cable, where all the four
pairs of twisted wires of the cable are used to
achieve high data transfer rates.
Uses 48-bit address

13. IMPLEMENTATION OF
GIGABIT ETHERNET

14. TENGIGABIT ETHERNET
 Upgrade to the data rate to 10 gbps.
 Make it compatible with standard,fast and gigabit Ethernet.
 Use the same 48 bit address.

15. Recent Trends
 Optical Ethernet Switches-FTTH,FTTB(10KM-50KM)
 GBIC Modules-also known as the small form-factor pluggable
multisource agreement (SFP MSA) module.
 The mini–GBIC is only about half the size, effectively
doubling the available capacity that can be designed into the
face of an equipment shelf.
 Resilient Packet Rings (RPR)-to define a high-performance,
high-availability optical transport suitable for carrier networks
in metropolitan service areas.

16. FRAME STRUCTURE OF
OPTICAL ETHERNET

17. ADVANTAGES
 To form an Ethernet, we do not need much cost. It is relatively
inexpensive.
 It does not require any switches or hubs
 Maintenance and administration are simple.
 Ethernet is a simple and widely understood technology.
 Optical Ethernet is the best technology for carrying IP traffic.
 Optical Ethernet and IP have grown up together

18. DISADVANTAGES
 It offers a nondeterministic service.
 It does not hold good for real-time applications as it requires
deterministic service.
 It provides connectionless communication over the network.

19. APPLICATIONS
 Advanced performance monitoring capabilities to ensure
compliance with SLA.
 Fast protection switching for reliability
 Efficient transport of Optical Ethernet from 10 Mb/s to 10
Gb/s.
 Increase capacity easily and instantly with software controls.
 Cost-effective delivery.

20. Conclusion
 Optical Ethernet transforms the corporate network into a key
competitive advantage.
 Optical Ethernet also provides network versatility to meet a
wide range of customer needs

21. Future Scope
 Optical Ethernet to the Consumer
 Optical Ethernet Area Networks
 Beyond 10 Gigabits
 Optical ethernet today includes
 LAN
 CAN
 MAN
 WAN
