I have two computers separated by a distance of 500m, can I use two adsl
modems (which I already have) to connect them using a simple phone cable back
to back.
The adsl modems have ethernet port.
You cannot terminate two DSL modems together, you need a
DSLAM on the other end of your DSL line.
Instead DSL providers offer IP VPN -- which is a type of DSL connection
without internet access, but for connecting several branch offices at
low cost. This typically costs no more than a regular DSL connection.
Think of it as poor man's MPLS cloud. Airtel offers IP VPN.
Or ask your telco operator for a leased line, and get them to loop it
at the exchange. This works only if both your end points are at
the same telephone exchange. What you end up getting is essentially
a private copper connection. You can then use any leased line modem
and get up to 16Mb/s speeds. BSN offers this setup, but don't tell
them you are using 16Mb/s modems!
There are 3rd party providers in Chennai (assuming you're in Chennai)
who can provide you point-to-point multi-mode fiber connectivity. You
can terminate both ends on to a suitable GBIC module and port on
a Ethernet switch. Since this is private fiber, you can run up to
10Gb/s on this link. I've never used these myself, so no first hand
experience to talk about.
Note that you cannot run your own cables through public property
without a telco or ISP license. Therefore any suggestions on running
your own Ethernet/serial/etc cable, is legal only if it's within your own
private property or campus.
