APON/BPON, EPON and GPON have been widely deployed. In November 2014, EPON had approximately 40 million deployed ports and ranks first in deployments. [47] As of 2015, GPON had a smaller market share, but is anticipated to reach $10.5 billion US dollars by 2020. [48] For TDM-PON, a passive optical splitter is used in the optical distribution ...
The GPON OMCI recommendation G.984.4 draws on G.983.2, which defines the BPON management model. However, G.984.4 removed all references to ATM. G.988 is a stand-alone OMCI recommendation and supersedes G.984.4 except for GPON specifics that are not defined in G.988. Future work on the PON management model is expected to appear only in the GPON ...
The 10 Gbit/s Ethernet Passive Optical Network standard, better known as 10G-EPON allows computer network connections over telecommunication provider infrastructure. The standard supports two configurations: symmetric, operating at 10 Gbit/s data rate in both directions, and asymmetric, operating at 10 Gbit/s in the downstream (provider to customer) direction and 1 Gbit/s in the upstream ...
This compares to the IEEE 802.3av standard for 10G-EPON based on Ethernet, which has standardised upstream rates of both 1 Gbit/s and 10 Gbit/s. [8] The 10 gigabit PON wavelengths (1577 nm down / 1270 nm up) differ from GPON and EPON (1490 nm down /1310 nm up), allowing it to coexist on the same fibre with either of the gigabit PONs. [9]
Depending on the underlying fiber technology, an OLT can be EPON, GPON, XG-PON or WDM. An OLT can have several ports, and each port can drive a single PON network with split ratios or splitting factors of around 1:32 or 1:64, meaning that for each port on the OLT, up to 32 or 64 ONUs at customer sites can be connected although this depends on ...
Higher Speed PON is the first PON system to use digital signal processing, succeeding both single-channel XGS-PON and multi-channel NG-PON2. [2] It provides upgrade paths for legacy PON generations such as GPON, XG-PON, XGS-PON, and 10G-EPON. [3]
In telecommunications, radio frequency over glass (RFoG) is a deep-fiber network design in which the coax portion of the hybrid fiber coax (HFC) network is replaced by a single-fiber passive optical network (PON). Downstream and return-path transmission use different wavelengths to share the same fiber (typically 1550 nm downstream, and 1310 nm ...
The Institute of Electrical and Electronics Engineers (IEEE) 802.3 standards committee published standards for a symmetric 1 Gbit/s EPON network, originally published in September 2004 as IEEE 802.3ah-2004, and a 10 Gbit/s EPON network permitting symmetric 10 Gbit/s and asymmetric 10 Gbit/s downstream 1 Gbit/s upstream, originally published in June 2009 as IEEE 802.3av-2009 also known as 10G-EPON.
