Next-Generation PON Evolution
A passive optical network features a point-to-multipoint (P2MP) architecture to provide broadband access. It is a telecommunications network that uses single, shared optical fiber in which inexpensive optical splitters to divide the single fiber into separate strands feeding individual subscribers. PON is called "passive", because, other than at the Central Office (CO) and subscriber endpoints, there are no active electronics within the access network. In passive optical system, a single fiber from a central office optical line terminal (OLT) is connected to optical network terminals (ONTs) or optical network units (ONUs) at customer premises. The image below is a PON system.
The operation of a PON system is not that complicated. Here presents how it works. As the following picture shows, a PON consists of an OLT at the service provider's central office and a number of ONUs or ONTs, near end users. In the basic method of operation for downstream distribution on one wavelength of light from OLT to ONU/ONT, all customers receive the same data. To put it simply, an OLT terminates the optical signals to as many as 16 to 128 customers. Hence the bandwidth of the fiber originally at the center office is shared among a group of users. The splitting of the network is accomplished by an optical splitter. These splitters can divide a single optical signal into multiple equal but lower-power signals and distribute the signals to users from OLT to ONU/ONT. The ONU usually communicates with an optical network terminal, which may be a separate box that connects the PON to TV sets, telephones, computers, or a wireless router. ONT and ONU are nearly the same device.
- Dramatic Cost Savings
- Higher Speed Performance for Today and Tomorrow
- Extremely Secure
PON is a highly attractive access solution because of cost and performance advantage, resulting from their nature as all-passive networks, point-to-multipoint architecture, and native Ethernet protocol. Fiberstore is specialized in optical communication products, certainly including the passive optical network equipment. PON splitters, OLTs, ONUs and ONTs are all offered in Fiberstore with highly quality and reasonable prices.
