10G-PON (also known as XG-PON or G.987) is a 2010 computer networking standard for data links, capable of delivering shared Internet access rates up to 10 Gbit/s (gigabits per second) over dark fiber. This is the ITU-T's next-generation standard following on from GPON or gigabit-capable PON.
ITU-T G.984 [1] is the series of standards for implementing a gigabit-capable passive optical network (GPON). It is commonly used to implement the link to the customer (the last kilometre , or last mile ) of fibre-to-the-premises ( FTTP ) services.
The ITU-T G.984 Gigabit-capable Passive Optical Networks (GPON, G-PON) standard, first defined in 2003, [14] represented an increase, compared to BPON, in both the total bandwidth and bandwidth efficiency through the use of larger, variable-length packets. Again, the standards permit several choices of bit rate, but the industry has converged ...
Gigabit Ethernet was the next iteration, increasing the speed to 1000 Mbit/s. The initial standard for Gigabit Ethernet was produced by the IEEE in June 1998 as IEEE 802.3z , and required optical fiber . 802.3z is commonly referred to as 1000BASE-X, where -X refers to either -CX, -SX, -LX, or (non-standard) -ZX.
NG-PON2 (also known as TWDM-PON), Next-Generation Passive Optical Network 2 is a 2015 telecommunications network standard for a passive optical network (PON). The standard was developed by ITU and details an architecture capable of total network throughput of 40 Gbit/s, corresponding to up to 10 Gbit/s symmetric upstream/downstream speeds available at each subscriber.

Higher Speed PON (also known as G.9804, HSP) is a family of ITU-T recommendations (computer networking standards) for data links, capable of delivering shared Internet access rates up to 50 Gbit/s (gigabits per second, Gbps). [1]
The competing MGBASE-T Alliance, stating the same faster Gigabit Ethernet objectives, was founded in December 2014. [15] In contrast to NBASE-T, the MGBASE-T said that their specifications would be open source. [16] IEEE 802.3's "2.5G/5GBASE-T Task Force" started working on the 2.5GBASE-T and 5GBASE-T standards in March 2015. [17]
