What are the solutions of fttp plan?

FTTP (FTTP), also called FTTH, refers to broadband telecommunication system. Based on optical cable, it uses optoelectronics to transmit high-end services such as telephone, broadband Internet and TV triple play to families or enterprises. So do you know what the fttp plan is?

What are the structures of fttp?

There are many kinds of fttp architectures, among which there are two main ones: one is a point-to-point topology, with one optical fiber from the central office to each user; The other is passive optical network (PON) with point-to-multipoint topology. Point-to-multipoint scheme can greatly reduce the number of optical transceivers and fiber consumption, and reduce the rack space required by the central office, which has cost advantages and has become the mainstream at present.

What are the fttp plans?

1. The developer installed weak current multimedia boxes in the user lobby and other places.

If enough space can be reserved in the weak current multimedia box (ONU equipment with at least 2FE+ 1POTS port can be placed), ONU equipment can be installed in the box, and household leather cables can be directly laid into the weak current multimedia box through household weak current concealed pipes during construction. It is suggested that the developer introduce the strong current into the weak current multimedia box, or that the developer, the property and the user inform the decoration company selected by the user in advance to introduce the strong current into the weak current multimedia box. Cables produced by ONU (Category 5 cables or white-coated cables) can also be notified to developers or property owners and users in advance by the decoration company selected by users, and indoor wiring can be considered uniformly.

If there is no installation location of ONU in the weak multimedia box, the following suggestions can be made to the developer:

A. The specification of weak current multimedia box is 450mm×350mm× 100mm, which is provided by Unicom. It is suggested that the developer replace the existing weak multimedia box, or install a new weak multimedia box near the strong power supply in the user's room, or install a new weak multimedia box at the user's door to meet the installation requirements of ONU equipment. It is suggested that the developer introduce the high voltage concealed pipe in the user's room into the newly installed weak current multimedia box.

B. If the developer disagrees with the above scheme A, the household rubber cord can be directly put into the weak multimedia box installed by the developer. When the user needs it, the cable is cold-connected, and then put in a suitable position in the user's room to supply power to ONU equipment, and the ONU equipment is exposed. Unicom may advise developers or properties to inform users before renovation. If the user has broadband demand, the decoration company selected by the user should consider indoor wiring in a unified way.

2. Weak current multimedia box is not installed in the developer's user room.

The specification of weak current multimedia box is 450mm×350mm× 100mm, which is provided by Unicom. It is suggested that developers install weak multimedia boxes or install weak multimedia boxes at the user's door to meet the installation requirements of ONU equipment. The developer introduced the high-voltage concealed pipe in the user's room into the newly installed weak multimedia box. Cables produced by ONU (Category 5 cables or white-coated cables) can be notified to developers or properties and users in advance by the decoration company selected by users, and indoor wiring should be considered uniformly.
