Qs for Md Reza team
1) Which are the other popular network analyzers available? and please mention whether they are commercial or freeware or shareware. which is the best?? why?
2) How do Wirishark differ from those apps?? pls mention advantages and disadvantages.
3) Can Wireshark be used on public networks like internet??

A1-the term crosstalk refers to any phenomenon by which a signal transmitted on one circuit or channel of a transmission system creates an undesired effect in another circuit or channel. Crosstalk is usually caused by undesired capacitive, inductive, or conductive coupling from one circuit, part of a circuit, or channel,to another.

A2-
Types of Fiber Optic Cable
1.Single Mode Fiber: Single-mode fibers are made up of a narrower core and allow a single data stream or mode to be transmitted over considerably long distances. In a narrower spectral width, a single mode fiber carries far more bandwidth, as compared to multi-mode fiber.
2.Multi-Mode Fiber: In comparison to single mode fiber, multi-mode fiber strands have a much thicker core. Multi-mode fiber allows multiple data streams to be transmitted over a single optical fiber by carrying data encoded, employing multiple light resources. However, the distance and available data bandwidth is a kind of drawback in multi-mode fiber. Multi-mode fiber is excellent for shorter distances, but is not compatible with the high bandwidth of single-mode fibers. This is used in backbone applications in buildings.
3.Plastic Fiber: Plastic Optical Fiber (POF), generally do not have the quality and optical purity that is needed for reliable data transmission. This makes them unfit for data transmission. These are mostly used for decorative and aesthetic transmission of light. POF has an edge over glass fiber, when it comes to entertainment and aesthetics on account of its cost and durability.
DIFFERENT BANDWIDTH AVAILABLE-
1.SINGLE MODE FIBER-Single mode fiber, with its relatively narrow diameter, typically has one mode in which it will propagate, 1310 or 1550nm
2.MULTI-MODE FIBER-Multimode fiber gives you high bandwidth at high speeds over medium distances. Light waves are dispersed into numerous paths, or modes, as they travel through the cable's core typically 850 or 1300nm. Typical multimode fiber core diameters are 50, 62.5, and 100 micrometers. However, in long cable runs (greater than 3000 feet , 914.4 meters), multiple paths of light can cause signal distortion at the receiving end, resulting in an unclear and incomplete data transmission.
3-PLASTIC FIBERLong-haul fiber-optic cable is often bundled with anywhere from 100 to 800 fibers per cable

yes there are some other popular software like softperfect and nmap but softperfect is not free and you have to by license for using that and nmap which is use mostly in unix OS and microsoft version does not work perfectly , and also it is not support the GUI .
for advantage and disadvantage of wireshark please refer to slide number 5 to 7 in our Presentation .
yes wireshark can use on internet you can install on your pc and capture all packet which you send and receive on the internet .
