Fibre Optic Broadband Ping

[craigj2k12]

Okay, ping on fibre optic broadband, lower than copper and adsl?

i know its coax cable delivered to your house from virgin, but is it this that gives the jitter, and the sometimes higher pings.

the only reason I ask is that im working in a school today and there connection is supplied on the north west learning grids fibre network.

the connection is 10/10 i think

some results had more jitter, is this normal for fibre broadband? should we be expecting the country to evolve into broadband with more and more jitter because of the fibre?

Think about how many people you were sharing that bandwidth with, it probably was getting used a fair bit which would have given the inconsistent jitter.

ADSL actually tends to have lower jitter than cable, it's nothing to do with the physical network but how the protocols that run over that network operate.

the other tests i did here had more jitter, but there were a few results with 1ms jitter. you have to remember this is school holidays

There's evidently some congestion on there somewhere else you'd be getting the full 10Mb.

[craigj2k12]

just checked with the technicians, they dont even know! they said it was either 10 or 20, but each user is capped at 5mb

OK - either way it's something specific to that, leased lines don't generally have much jitter.

Cable broadband is jittery due to how the bandwidth is shared, other networks, including active and passive optical networks, are better.
