Transmission loss on DSL Vs OpticalFiber

[anandkrishnantc]

Hello everyone,
currently I am using AirTel DSL for broadband . Some sources say the transmission loss on DSL connection is large compared to Optical Fiber connection. I have an option to get ACT optical fiber in my area. Any idea how big is this loss on DSL? I am concerned because my 60 GB FUL is reaching so quickly without much downloading, only using by youtube.

I think you're confusing between transmission loss in electricity to transmission loss of signal strength & quality in adsl line.
In internet, with transmission loss, you will get lesser speeds the further you go away from the exchange. Data packets are not lost. So that extra data usage is from your side and has nothing to do with signal strength or quality from exchange.

thanks. I mean the data error in transfer and re-transfer occurs. Is this more for DSL compared to Optical fiber?

There is practically no external interference in OFC .. what ever loss happens is due to the fiber inside.

DSL is run over copper cables which are pretty haphazardous .. There are multiple joints and reconnection which would affect signal quality.

No. At the max, you're line would disconnect and reconnect. During this time if you're downloading from servers that don't support reconnection, then you would be downloading data from the very beginning all over again. YouTube supports reconnection, since its a streaming server. So in your case, data consumed will be actual data due to watching videos in high definition or maybe watching too many videos. Even a 10 minutes video would be approx around 100MB if it was of good quality and size.

Copper is quicker to repair than fibre. Does not need fancy splicing equipment etc. Ask ACT to tell you how quickly they can repair a cut optic fiber. If its in hours thats one thing, days is another.

Yes, I am seeing youtube eatsup a lot of bandwidth. And my 3 year boy is one of the highest user of youtube (thanks to iPad)
