Knowledge Of Fiber Optic Access Network, How Much Do You Know ?
Jan 11, 2019

Do you know what a fiber access network is? The so-called fiber access network refers to the application form in which the optical fiber is used as the main transmission medium in the access network to realize user information transmission. It is not a fiber transmission system in the traditional sense, but a special design designed for the access network environment. Optical fiber transmission network.

What types of fiber access networks can I have? The fiber access network can be divided into two major categories: active optical network (AON) and passive optical network (PON). The active optical network can be further divided into SDH-based AON and PDH-based AON; passive optical networks can be divided into narrowband PON and broadband PON.

Since the transmission medium used by the fiber access network is an optical fiber, the fiber access network can be classified into FTTC (fiber to the roadside), FTTZ (fiber to the cell), and FTTB (fiber to the building) according to the degree of the fiber penetration into the user group. , FTTO (Fiber to the Office) and FTTH (Fiber to the Home), they are collectively referred to as FTTx.
