Why GPOn?

@Dark_Nate Just to mention,I prefer fiber personally because it is very less suspectible to electronic interference in household as well as to AC and in most areas fiber are going through overhead by electricity poles and interference become a large factor.
Also,2W per user upto 40 Km is reasonable for fiber.Whereas cable have higher power requirements.
This is the primary reason I have seen in almost each professional presentation in my experience.

I have JIO fiber, they have such an extensive coverage if it's not XG_PON from start, I wonder how are they gonna upgrade such an extensive infra and some new comer doing the same to them like they have done to others 😛

The beauty of pon is the ease of upgrades.
To move to x-pon like 10g or 40g we can just change the cpe(ont) and the olt to finish the upgrade.

So we are not constrained by theoretical bandwidth of optical medium. :wow:

@Realme Exactly.
Optical medium has much more potential which we are yet to explore.

Why are you telling me that? Everybody knows Fibre Optics is the most superior for now.

@Realme As far as data is concerned,we have succeeded in getting 1 terabit of speed over a single pair of fiber.So yes,we are not limited my speed as we can use various light frequency.
Imagine using two different light frequency,it will multiply the bandwidth.
This is the primary reason for heavy upgradation to fiber.
But the implementation is very bad.
Specially under bharatnet,we are using just 2 pair of fiber which limits the specific requirements-:
It could be leased to private operators.
It could be used to lease to servers.
The cost of armoured fiber cable is 5-7 rs per meter for 2 pair.
10 rs per meter is cost of 10 pair unarmoured cable.
And while laying under ground fiber...Armoured cable is of no use.
I still cannot understand why the SO CALLED SMART IAS OFFICERS COULD NOT THINK ABOUT THIS.
Since one pair have on OLT.Thus many limitations could have been overcome.

@vignesh_venkatesan :Why ACT preferred switches/CAT than other ISPS like Airtel/BSNL on GPON?

When act started operations many years back fiber was not cheap and the plans were max 40mbps.
So they took intermediate path of laying fiber till building/lane to decrease cost as 1gbps would never be used in those days plans.

Nowadays with speed increase instead of shunning ol practice they are giving option of both ftth or fttb/n. For higher end plans(gigabit) they giving ont for free too.

The question who will use above 1gbps speeds? Lets see from 10 years from now also our network requirments wont change so drastically. Lets admit that if Internet of Things(IOT) may become popular where smart homes all come , but their main requirements is not huge bandwidth but extremely low latencies. I think these isps should focus mainly on decreasing latencies for their network in the coming years.

@philip I agree, low latency is more important. Imagine 10 Mbps connection with <1ms latency vs 50 Mbps with 300ms latency.

Latency is largely ignored by Indian ISPs.

If you are saying that who will use this high speed.
Considering the fragmentation occuring in modern time where each device have its own data requirement,multiple streams should be great.Having more virtually isolated data stream would be great as prioritisation is processing power intensive.Imagine virtually dividing your 50 Mbps to 5 Mbps each of 10 streams which can be combined if needed for streaming.
It is one of the solution being worked on by Cisco and others.
It would hugely improve latency as more open and better prioritized stream will be available.
In present times,VoIP is prioritised as most backend instrument already support it and ISP have specified QoS rule.
But there is no such rule for other tasks which rely more on latency.
If all ISP can come on a standard rule to prioritise the latency intensive tasks then we can look to great idea else visual isolation of streams is a workable idea as it would only need software updates.
PS Actually virtual isolation is same as QoS used for VOIP but instead of rules set by ISP,we can set it if the port details and packet details are standardized.
Like if you think the idea should be promoted.
