Synchronous vs Asynchronous Fibre

[DeSLAM]

So is fibre in SA not being launched on a "wing and a prayer" considering all these asynchronous offerings. Is the fibre network infrastructure really capable of dealing with national synchronous throughput. It sure doesn't look that way.

You see offerings like this 10 Mbps download speed / Up to 1 Mbps upload speed

Seriously? Seems like the fibre roll-out in SA is crippled from the onset.

Synchronous fibre offers a fixed clock speed and is guaranteed to transmit data at a specific rate up and down ensuring that buffering is practically unnecessary.

So essentially asynchronous fibre - which is becoming typical in many offerings - is launching as a "mother buffer"...fibre.

In the old days 99% of home users hardly used the upload component, the odd email here, and traffic requesting downloads. Hence ADSL was designed this way to make it cheaper.

These days its a little bit more used due to facetime, skype, broadcasting your live stream, but the majority of the time, people do not use much of the upload

So, why pay for it if it wont be used, if the isp can rather allocated bandwidth for downloads (on networks like GPON), and make the product cheaper - I don't see why not

Just realised I thought you meant symmetrical not synchronous

For synchronous fibre you would require 2 strands of fibre for each client, where asynchronous you only need one fibre strand. All comes down to cost
