The IEEE802.3bk standard expands EPON's fiber loss budget

According to relevant sources, IEEE has announced the approval of the Ethernet revision of the standard IEEE 802.
3bk, mainly to extend the Ethernet passive optical network physical layer specifications and management parameters
.
IEEE said the new specification aims to make network ownership cost-effective while improving Ethernet passive optical network (EPON) infrastructure
for high-density and longer-reaching applications.

IEEE further strengthens the standardization of EPON's fiber access systems

With the gradual popularization of EPON, the problems highlighted in it have gradually emerged
.
These measures include EPON cost-effectiveness in rural areas with low customer density, as each port provides users with branches, shares links between users with a higher concentration of users, and provides services to users with the closest network hub that is larger than the original specifications
.
Marek of the EPON Task Force said, "As operators around the world seek to build higher density and more cost-effective fiber access networks to connect more customers, service providers are grappling with some scalability challenges in delivering mobile backhaul and guaranteeing connectivity to remote customers.
"

While the IEEE 802.
3bk extension, a market-oriented effort to modify the Ethernet standard, allows a given EPON deployment to support more users over longer distances than was previously possible, IEEE is already discussing revisions
to the new standard.
IEEE802.
3bk solves these problems by modifying the base IEEE 802.
3 Ethernet standard to support optical loss budgets beyond previously specified
.
It is expected that the expansion of the IEEE 802.
3bk standard will allow for the expansion of EPON service areas and reduce the cost per user, reduce the central office equipment footprint and energy consumption (per customer), the cost of service upgrades, and fiber deployment, as well as increase the density of customers at the branch office

CommScope adds EPON and GPON production lines

CommScope said on September 7 that it plans to expand its existing fiber-to-the-home (FTTH) product line, adding PON and GPON equipment production lines
。 CompScope Edwin claims: "We are pleased to add new products based on the IEEE802.
3bk standard, which will enable service providers to better utilize the already deployed fiber optic digital subscribers can deliver each OLT (Optical Line Termination) port, through the network architecture and standards of engineers, with Bright House Networks and others will significantly reduce the overall cost in EPON??" The first mile of fiber access is served
.
”

He also said he looks forward to future projects within the IEEE 802.
3 Working Group, primarily from a compatibility perspective, where our fiber distribution network supports 1G-EPON and 10G-EPON next-generation products, which, once completed, will provide cost-effective solutions for faster fiber access

White Paper: GPON vs.
EPON

Some analysis has pointed out that although the general concepts of GPON and EPON are the same (PON operation, ODN architecture, wavelength planning, and applications), their operation is very different from the functions and services
they support.
EPON refers to being a home-grown Ethernet solution that takes full advantage of the features, compatibility, and performance of the Ethernet protocol, while GPON is considered to be a technology
that utilizes SONET/SDH and GFP (Universal Framing Protocol) to transport Ethernet.
A white paper points out that since the mid-90s of the 20th century, passive optical network (PON) technology has been developed and major development activities have occurred in the early 21st century to develop gigabit speed solutions designed to provide Ethernet and IP services
.
Two very different solutions are developed by IEEE and ITU-T, namely EPON and GPON
