Standard amendment defines Ethernet Media Access Control (MAC) parameters, physical layer specifications, and management parameters to extend 25 Gb/s Ethernet well beyond 100 meters.

IEEE and the IEEE Standards Association (IEEE-SA) on Mar. 22 announced the publishing and availability of IEEE 802.3cc-2017Standard for Ethernet Amendment: Physical Layer and Management Parameters for Serial 25 Gb/s Ethernet Operation Over Single-Mode Fiber.

Per an IEEE statement, "The new amendment to IEEE 802.3 represents the first available industry standard developed specifically to address the growing need for increased Ethernet speeds for enterprise, campus and metro Ethernet speeds exceeding 10 Gb/s, and that can support reaches up to 10 and 40 kilometers over single-mode fiber (SMF)."

“IEEE 802.3cc provides network operators a cost-effective upgrade path to 25 Gb/s that minimizes network design, installation and maintenance costs by preserving current network architecture, management, and software,” said David Lewis, chair, IEEE 802.3cc 25 Gb/s Ethernet over Single-Mode Fiber Task Force.

Per IEEE, "IEEE 802.3cc supports efficient Ethernet operation and defines single-lane 25 Gb/s PHYs for operation over single-mode fiber with lengths up to 10 km and 40 km. IEEE 802.3cc addresses the requirement in metropolitan networks, where the core operates at 100 Gb/s, for tributary feeds at rates higher than 10 Gb/s. By enabling extended 25 Gb/s reaches, IEEE 802.3cc matches the per-lane rate of several 100 Gb/s PMDs currently used in these networks."

Lewis added, “The work of the IEEE 802.3cc 25 Gb/s Ethernet over Single-Mode Fiber Task Force has demonstrated how responding quickly to industry demand for greater energy-efficient Ethernet capabilities can be achieved in a manner that can reduce both operational costs, and the environmental footprint of network upgrades.”
