Five pon ports, two first-class optical fiber junction boxes, and 33 second-class optical fiber junction boxes. How many wires are used and how many users can they take (regardless of optical attenuation)? The OLT pon port transmits light to the branch box for primary separation, and then to the optical fiber separation box for secondary separation. According to the calculation that the optical splitter is 1:8 (practical application), each PON port can carry 64 households, and if there are 5 households, it is 320 households.

According to the fiber sorting boxes you provided, each box can carry 16 households, and 33 households are 528 households.

The main fiber core can be expanded, so this FTTH project can actually cover 528 households (actual installation).
