Hello, i've been searching about fiber optic connections and i have the following questions:
1)How much difference in speed can fiber have over copper? eg. copper:13 mbps, fiber:?? (real numbers)
2)Is there any sense in installing fiber cables in my home while i am still recieving data from my interner provider's cabinet through copper?
3)How can i identify a fiber optic router?
4)Which type of fiber optic cable is better and is there any sense into picking the most expensive over the low-cost ones?
5)Is it easy to install fiber optic cabling in my home?

An answer to any question above is appreciated. Thank you.
 
1. Copper is capable of 10GB/sec connection. Fibre connection' plus is that is less suspectible (if at all) to interferences, and can go over longer distances.
2. Not at all. Our grandchildren probably will have this dilemma.
3. You will need to move to $10k enterprise routers to see fiber optic links. If you're talking about "fibre-to-the-home", this is achieved with small fiber-to-Ethernet converter.
4.
5. Not easier than pulling Ethernet cable. Terminating fibre links is much more difficult.

So - if Google is offeering you a fibre connection, take it. It will end at regular Ethernet jack.
 
Running fiber inside you house is likely a complete waste of time.

You can if you are very anal about it calculate how much faster data will flow in the cables themselves. This is reduction in time it takes the first bit to get there...the actual time it takes to transfer the data is based on the interface speed. Copper cable runs at about 2/3 the speed of light. So you can do the math of how many pico seconds the difference is even in a maximum 100m copper cable. It is best to think of both as having the same propagation delays since the data rate is controlled by how fast the data is clocked onto the connection not the speed of the media.

Fiber device for 1g have come way down but you can't think to compare price to a $50 8 port copper switch. You will pay a couple hundred dollars a port just for the optics that go into the switch and then you must pay for the switch itself.

You also need to decide on speed most time you use copper in short distance applications unless you plan to run 40g or 100g connections.

So step 1 how much budget do you have. Just simple fiber patch cable will cost you $30 each and that is for the low end cheap ones.
 
I only can answer you the first question, help can help you
Copper suffers from a significant signal-loss issue. To accurately read a signal, you have to know the exact moment the signal has stopped and the exact moment it began. As a signal is forced to travel farther, the difference between a start and a stop (zero and one) gets very fuzzy. Copper is best used for maintaining a continuous electrical current since it’s a great conductor. However, for signalling, it remains a very poor material. It’s still great for local networks, but not necessarily something we should be using for global communication infrastructure, considering that Cat6a copper cables can lose 94 percent of their signal at 100 meters distance (this is the industrial maximum for signal loss through copper).
