ur ping time is higher than mine

Luke Skywalker

No it is not. Also I live far from my exchange..
My ping is with 56 byte of data & yours is with 32 byte . Do the math & tell me which is faster.

Optic is better not due to latency but due to very high bandwidth & very low attenuation.

Rcom

don't give silly excuses like i live far from exchange my plan cost this that etc main thing is who get the best ping time.


bottom line is copper don't come in league of Fiber-Optics.

Rcom

now with 1024 bytes

I have reposted the answer & edited it after reading your ping. Mine is infact 2/3rd yours taking into consideration the amount of data transfer. Yours is just 32 bytes & mine is 56 bytes.

1024 bytes still mine is fast with 1MB load

Beleive whatever you want but if you ever happen to meet a communication engineer ask him why optic is better & is it have better latency than copper.

Reason I have given is that due to attenuation & bandwidth optic is better than copper .

Not due to latency.

That is the mistake by me. Latency don't depend upon amount of data transfer.
I was confused on it. But not on latency of various medium for communication.

1. Fiber optic is more efficient and secure than copper cabling, transmitting information with greater fidelity. Fiber links offer more than 1,000 times as much bandwidth over distances more than 100 times farther than copper, and extra data security is provided since it is more difficult to tap than copper cable.

2. Fiber optic cable can carry more data than copper and for longer distances. It can transmit a signal as far as 80 km or beyond without need for amplification.

3. The glass-based cables don’t conduct electricity, which eliminates the need for grounding and makes them immune to electrical interference, even lightning. They can be used outdoors and in proximity to electrical cables.

4. Glass fibers are virtually free from corrosion. While copper is sensitive to water and chemicals, fiber optic runs almost no risk of being damaged by harsh elements, and can endure “living conditions” that coaxial cable cannot, such as direct contact with soil. And, while you may not have considered it....

5. Fiber-optic cabling poses no threat of physical injury if it breaks. Since it transmits light, not electricity, handlers run no risk of injury from fire, sparking, or electrocution.

In 1999, an estimated $14.6 billion was spent on fiber optics items. These figures were attributed to the growing use of the Internet. Companies are increasingly using fiber optics for other purposes. Applications exist for manufacturing plants, computer offices, telemarketing networks, Internet broadband companies, online video providers, Ethernet users, medical offices, hospitals, financial institutions, and communications companies.

Latency is the amount of time a message takes to traverse a system.

In a computer network, it is an expression of how much time it takes for a packet of data to get from one designated point to another. It is sometimes measured as the time required for a packet to be returned to its sender.

Latency depends on the speed of the transmission medium (e.g., copper wire, optical fiber or radio waves) and the delays in the transmission by devices along the way (e.g., routers and modems). A low latency indicates a high network efficiency.

Latency and throughput are the two most fundamental measures of network performance. They are closely related, but whereas latency measures the amount of time between the start of an action and its completion, throughput is the total number of such actions that occur in a given amount of time.

Sending data in large packets has a higher throughput than sending the same data in small packets both because of the smaller number of packet headers and because of reduced startup and queuing latency. If the data is streamed (i.e., sent in a continuous flow), propagation latency has little effect on throughput, but if the system waits for an acknowledgment after each packet before sending the next, the resulting high propagation latency will greatly reduce throughput.

Latency is also an important consideration with regard to other aspects of computers, particularly where real time (i.e., nearly instantaneous) response is required. For example, in some Internet games, a high latency (also called lag) can add to the difficulty of determining which player performed an action first (such as shooting an opponent or answering a question). In playing computer-based musical instruments, latencies greater than 100 milliseconds make it difficult for players to get the nearly instantaneous feedback that they require.

Nowhere it mention latency is better than copper.
Fidelity is ability of a medium to reproduce same type of data.

Speed for copper is .95 of light
& speed for optic is .65 of light.

Rcom

can't u read "Latency depends on the speed of the transmission medium" and fiber optics carry more speed than copper wire.

Luke Skywalker

Reason you have given for optic are more valid than latency one.
Nowhere have I said that copper is better than optic in every respects. In fact I have given reasons in brief why it worst overall.

That is wrong. Light travel at optic at 2/3rd speed & in copper at .95 the speed of light & in cable at .6.

Most people think optic mean data transfer at speed of light.

Optic is better than copper I know that & everyone knows that but its latency is not better than copper wire.

Just check this fact out.

Bandwidth!=latency.

Rcom

@luke:copper may give good latency but it can't carry that latency in long distance.
