[pkuser2k12]

KARACHI: About 10-20 percent of Internet and other communication services in the country have suffered after a submarine optic-fiber communications cable was reportedly damaged last week, Geo News reported.



According to sources in Pakistan Telecommunication Company Limited (PTCL), the undersea cable developed a fault on Friday, March 1, 2013.



The world consortium for the submarine Internet cable says their technical team has nailed down the exact location of the fault and repair was in progress.

Why do we need a undersea internet link?

Why do we need a undersea internet link?

Previously, almost all communication was done via intercontinental satellite: telephone calls to TV signals, almost everything was received and sent through them. At the beginning of the Internet, satellite links were also very common, but the high cost, very high latency and low bandwidth eventually caused the satellite to lose the race for the fiber links. Today, satellites are used as links as backup and remote access option for remote areas, but more than 99% of traffic goes through intercontinental fiber links, which today involve 6 of the 7 continents, leaving out only Antarctica.

Hope this helps.

I understand this thing, the transitioning of comms from Satellite to fiber optic, but why under sea and not over land?

We have link with Iran and also India. Or does Iran have another system or something like that due to sanctions etc?

Undersea is safer.

Submarine cables are laid using special cable layer ships, such as the modern René Descartes, operated by France Telecom Marine.

Number of reasons:

- Shortest route / length for countries with a sea shore.
- Same cable suffices for a number of subscriber countries.
- Laid across international waters hence no local issues / clearances.
- Least disruption. Most damage takes place when ships drag their anchor across ocean bed.
- Repairs too need no clearances.
- No rental paid .
- Overland route would need protection, maintenance & would be susceptible to local disturbances. One nation could deny it to those ' down stream'.
