How To Emulate Fiber Optics In GNS3
This post is concerned about how to emulate Fiber Optics on GNS3. But first we need to know some key points.
Synchronous optical network (SONET), a synchronous transmission system defined by ANSI, is an international standard transmission protocol. It adopts optical transmission.
In SDH defined by CCIT (today’s ITU-T), adoption of synchronous multiplexing and flexible mapping allows you to add/drop low-speed tributary signals from SDH signal without large amount of multiplexing/demultiplexing devices. This reduces signal attenuation and device investment.

Packet over SONET/SDH (POS) is a technology popular in WAN and MAN. It can support packet data such as IP packets.
POS maps length-variable packets directly to SONET synchronous payloads and uses the SONET physical layer transmission standard. It offers high-speed, reliable, and point-to-point data connectivity.
The POS interface on your device supports PPP, Frame Relay, and HDLC at the data link layer and IP at the network layer. Its transmission rate can vary with devices. For example, in the sequence of STM-1 (155 Mbps), STM-4c (622 Mbps) and STM-16c/STM-16 (2.5 Gbps), the rate of each level is four times that of the immediate lower level.

Configuration:
Note that the fiber optics interface (POS) is available only on Cisco router 7200 series.
Right click the router and choose configure.
This feature is useful for emulating Fiber Channels and other features related to fiber. the only missed feature is that GNS3 does not support capturing packets of fiber ports using wireshark.
I hope that has been informative to you.
