What is FTTP, FTTH, FTTB, and FTTD?
FTTP stands for Fiber To The Premises which is one type of fiber optic communication delivery in which a optical fiber connection is directly run to the customers' premises. The P(premises)can be business, commercial, institutional and other applications where fiber network connections are distributed to a campus, set of structures, or high density building with a centrally located network operations center. Some other FTTx such as FTTN(fiber to the node), FTTC(fiber to the curb) still depend on copper wires for "last mile" (final connection) to the customers' premises which contrasts with FTTP. FTTP can be further categorized into FTTH(fiber to the home), FTTB(fiber to the building), etc.

Network construction of FTTP
FTTP network can be divided into two major parts: optical portion and electrical portion.


1. Optical portion
Optical portion of the FTTP network is responsible for carrying optical signal to the electrical portion (electrical portion is located in the customer's telecom room). Two fiber configurations exist for the FTTP optical portion. These are direct fiber link and shared fiber link.

Direct fiber link is the simplest form. One fiber is used for directly connecting the central office to one customer. This type of connection provides the customer the biggest bandwidth but is also the most expensive configuration. Shared fiber link means a single fiber leaving the service providers central office is shared by many customers. Only at the final moment, the fiber is split into many individual fiber to each customer.

There are two major competing technologies for the shared fiber link configuration: active optical network (AON) and passive optical
