Does RFoG use DOCSIS?
RFoG delivers the same services as an RF/DOCSIS/HFC network, with the added benefit of improved noise performance and increased usable RF spectrum in both the downstream and return-path directions.
What is RFoG used for?
RFoG is used to increase network system capacity, often in point-to-multipoint systems. This enables fiber to the premises (FTTP) communications that are less labor-intensive, in terms of installation, and more reliant on traditional hardware for controls.
What does RFoG stand for?
Radio Frequency over Glass (RFoG) is used to replace the coaxial part of the HFC network with single fiber transport. The application of RFoG was first defined by the Society of Cable Telecommunications Engineers (SCTE).
What wavelengths are used in an RFoG network?
The RFoG WDM module is designed to satisfy wavelength management requirements where 1310, 1490, 1550 and 1590 / 1610nm wavelengths are used in passive optical network applications.
How are optical splitters used in the forward path?
How are optical splitters used in the forward path? In the forward path, optical splitters are used as passive branching devices that divide an optical signal across multiple output fibers. Water causes the glass fiber to become opaque, which degrades the signal as its transported through the fiber.
What is difference between GPON and EPON?
In fact, both GPON and EPON deliver Ethernet to the end user. The difference is GPON is a purpose-built point to multi-point transport protocol while EPON conscripts Ethernet to attempt the same inefficiently.
What is a hybrid fiber optic cable?
A hybrid fiber coaxial (HFC) network is a telecommunication technology in which optical fiber cable and coaxial cable are used in different portions of a network to carry broadband content (such as video, data, and voice). 2) The higher bandwidth supports reverse paths for interactive data flowing back from the user.
How many times can a Fibre be split?
A typical split ratio in a PON application is 1:32, meaning one incoming fiber split into 32 outputs. And the qualified fiber optic signal can be transmitted over 20 km. If the distance between the OLT and ONT is small (in 5 km), you can consider about 1:64.
What is GPON EPON modem?
GPON (Gigabit Passive Optical Networking) and EPON (Ethernet Passive Optical Networking) are variations of PON (Passive Optical Networking) technology, or Fiber to the Home (FTTH) networks being deployed by Internet Service Providers (ISPs).
Is GPON shared bandwidth?
For example, GPON allows 2,300 Mbits/sec (i.e. 2.5-Gbits/sec line rate x efficiency) of bandwidth to be shared by 64 customers, or about 35 Mbits/sec per customer. The higher bandwidth and split ratio makes GPON technology particularly suitable for multi-tenant or multi-dwelling buildings.
