Is GPON and EPON same?
GPON supports 1 Gbps asymmetrical operation. Another key distinction is the protocol support for transport of data packets between access network equipment. BPON is based on ATM, GPON uses native Ethernet and GEPON supports ATM, Ethernet and WDM using a superset multi-protocol layer.
What is the meaning of GPON?
Gigabyte Passive Optical Network
Gigabyte Passive Optical Network, known as GPON, rely on fiber optic cables to deliver video, data and voice signals.
Can GPON use EPON?
The Differences GPON is purposely built as a point-to-mulitpoint protocol. EPON calls upon Ethernet to function the same as GPON. In other words, GPON is efficient and EPON is not.
What is the difference between FTTH and GPON?
GPON is a telecommunications access technology that uses fiber-optic cabling to reach the user. This fiber optic technology provides faster data transmission and reception through a single fiber, with a point-to-multipoint architecture, which allows home optical fiber (FTTH), or a building (FTTB).
What is difference between GPON and FTTH?
Why do we need GPON?
Its advantage is especially strong where minimizing maintenance work is important. The GPON design includes ATM encapsulation. This makes it convenient to deploy in networks which use an ATM backbone. A GPON can replace existing copper-wire cabling and deliver higher data speeds with greater reliability.
Which is better GPON or EPON line coding?
One advantage is GPON’s use of NRZ line coding versus EPON’s use of 8B10B line coding, which provides for some marginal bandwidth efficiency. This is why EPON has a line rate of 1.2 Gbps but a maximum capacity of 1 Gbps while GPON’s maximum capacity is the 1.2 or 2.4 Gbps line rate.
How does GPON support point to point connections?
GPON is architected specifically to support point-to-point connections; thus, where Ethernet bridging or LAN/VLAN support is required, this must be done upstream of the OLT with overlay equipment. Conversely, delivery of MEF-defined services are standard capabilities of EPON systems.
Which is an advantage of a GPON router?
Originally, GPON had a technical market advantage in that its transmission convergence layer natively accommodated not only encapsulation of native Ethernet frames, but also of ATM cells and TDM services. This capability made it an ideal choice for carriers wishing to deliver simultaneous voice and data services to their customers.
Which is better GPON or ITU-T g.984.x?
The GPON standard has an advantage of market timing in North America; the ITU-T G.984.x series standards were ratified in 2003, while the IEEE did not ratify the 802.3ah standard until 2004, one year later.
