Are the optical splitters only in the SUB BOX and END BOX?

Is HUB BOX an optical closure? Does the HUB box have optical splitters?

Depending on the architecture, the optical splitters can be standard e.g. 1:8 in SUB BOX and 1:8 in END BOX or a combination of unbalanced optical splitters 90/10 in SUB BOX and then in END BOX 1:8? Or are only unbalanced optical splitters used?

How many optical fibers do feeder, distribution and drop optical cables have? I found information 12 fibers for the feeder with MPO connectors, and the other cables one fiber each.

What are the optical connectors on these cables called? What level of protection do they have?

What is the function of ATB if the drop cable has an optical connector? Why don't we connect ONT directly to the drop cable?

Hello, friend!


1. The hub can also house an optical splitter. Need to look at the split ratio.

2. The hub box is an optical closure, and it is a closure that can house optical splitter, depending on the networking split ratio in the network planning.

3. The sub-box is a 1:9 optical splitter with an unequal ratio, and the end-box is a 1:8 optical splitter.

4. The feeder section is a multi-core cable. The rear distribution section and drop end are both 1-core.

5. The cascading between boxes is called distribution cable and distribution cable, and the drop cable is called drop cable and drop cable.IP68 protection under the ground and IP65 protection above the ground

6. At present, drop cables do not have a head. The main purpose is to prevent the excess length from being difficult to manage. Therefore, they are spliced to the ATB and then connected to the ONT. If the excess length is not managed, drop cables directly take the lead and can be directly connected to the ONT.


Thanks!

Hello，friend!

The value depends on the application scenario. The application varies according to the application scenario.Generally, the optical splitter is in the box.

Does this mean that the HUB box can also have an optical splitter?
Does this mean that all the possibilities for optical splitters, which I am writing about, are possible?
What are the optical connectors on these cables called? What level of protection do they have?
What is the function of ATB if the drop cable has an optical connector? Why don't we connect ONT directly to the drop cable?
