@Lolita_Magnum @Life_Warrior anyone of you know exactly what's their uplink capacity?
All I know (from an excitel ground level technician) about his area is as follows...
They use 16 Port
GPON OLT which serves technically upto 2048 connections. They have about 950-100 customers in their area. Here's the picture he shared where we can see the OLT.

As it is a
Syrotech OLT -
SY-GPON-16OLT » Syrotech
We can see that it has 16 PON ports & 4
Gigabit SFP ports (can someone let me know why these 4 Gigabit SFP ports are used?) As well as 4 10 Gigabit SFP+ ports for uplink.
As we can see in the image above. They have all 16 PON output ports occupied. Also they just have one 10 Gig uplink SFP port plugged in with dual mode (multimode) fiber 1 Up & 1 Down. Means they're getting 10 Gig uplink for around 1000 Connections.
So my main questions are...
1. How are they able to serve around 1000 customers with just 10 Gig.
2. Is the 10 Gig uplink provided by
Tata symmetrical? 10 up 10 down? (I think yes as it's a multimode fiber)
3. Isn't this a bottleneck? Or either they never reach peak bandwidth.
4. What if they hit the peak bandwidth? Do they add another 10 Gig link to the remaining 3 SFP+ ports?
5. As per any of your experience what is the cost of that 10 Gig link they take from tata?
6. What if the main line breaks? Is it underground or overhead?
7. I've seen a big fat orange multicore fiber going inside my excitel LCO office. Is that the backbone?
8. Who takes the responsibility & care of the tata uplink? Tata, excitel or LCO? (Probably tata)
9. Why those guys are so secretive about the uplink? They share everything but not the uplink.
10. Just like excitel can we also take 10 Gig uplink from tata? What are the problems we're gonna face?
11. Can't excitel just fill up all those 4 ports with all 10+10+10+10=40 Gbps link & start providing plans up to 1Gbps?
12. Is the backbone directly connected to cities via hubs & POP's to excitel's main backbone network?
13. What is their split ratio per output PON port? What dBm standards they have?
14. Does Excitel has standards like how many connections they can give per port? Or they can give up to 128 connections if the dBm power to each connection is fine.
Feel free to answer any question if you aren't sure about other questions.
