IEEE's New Standard Supports Fast Ethernet Over Distances Over Fiber

  • IEEE Standards Association
PISCATAWAY, NJ — IEEE, the world's largest technical professional organization dedicated to advancing technology for humanity, and the IEEE Standards Association (IEEE-SA), announced the publishing and availability of IEEE 802.3cc-2017—Standard for Ethernet Amendment: Physical Layer and Management Parameters for Serial 25 Gbps Ethernet Operation Over Single-Mode Fiber.

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 Gbps, and that can support reaches up to 10 and 40 kilometers over single-mode fiber (SMF).

Upgrade Path to 25 Gbps for Network Operators
“IEEE 802.3cc provides network operators a cost-effective upgrade path to 25 Gbps that minimizes network design, installation and maintenance costs by preserving current network architecture, management, and software,” said David Lewis, chair, IEEE 802.3cc 25 Gbps Ethernet over Single-Mode Fiber Task Force. “The work of the IEEE 802.3cc 25 Gbps 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.”

IEEE 802.3cc supports efficient Ethernet operation and defines single-lane 25 Gbps 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 Gbps, for tributary feeds at rates higher than 10 Gbps. By enabling extended 25 Gbps reaches, IEEE 802.3cc matches the per-lane rate of several 100 Gbps PMDs currently used in these networks.

IEEE 802.3cc is available for purchase at the IEEE Standards Store.

Deployment of technology defined by IEEE 802 standards is already globally pervasive, driven by the ever-growing needs of data networks around the world. New application areas are constantly being considered that might leverage IEEE 802 standards in their networks from wireless, through twisted-pair cabling, to fiber-optic cabling solutions. To better address the needs of all of these areas, IEEE 802 standards are constantly evolving and expanding. The success of IEEE 802 standards — from their inception through today — has been their fair, open and transparent development process.
