IEEE 802.3cc standard for 25 Gigabit Ethernet over single-mode fiber published

The IEE and the IEEE Standards Association (IEEE-SA) say the recently ratified "IEEE 802.3cc-2017—Standard for Ethernet Amendment: Physical Layer and Management Parameters for Serial 25 Gb/s Ethernet Operation Over Single-Mode Fiber" standard has been published and is now available for use. The specifications point the way toward the development of 25 Gigabit Ethernet transmission technology for enterprise, campus, and metro Ethernet applications at reaches up to 10 and 40 km via single-mode fiber (SMF).

The IEE and the IEEE Standards Association (IEEE-SA) say the recently ratified "IEEE 802.3cc-2017—Standard for Ethernet Amendment: Physical Layer and Management Parameters for Serial 25 Gb/s Ethernet Operation Over Single-Mode Fiber" standard has been published and is now available for use. The specifications point the way toward the development of 25 Gigabit Ethernet transmission technology for enterprise, campus, and metro Ethernet applications at reaches up to 10 and 40 km via single-mode fiber (SMF).

IEEE 802.3cc defines single-lane 25-Gbps PHYs for the up to 10 km and 40 km use cases. The IEEE envisions the new specifications will see use in applications require transmission at rates greater than 10 Gbps, likely acting as tributaries to 100-Gbps core networks. The IEEE notes that 25 Gigabit Ethernet matches the per-lane rate of several 100-Gbps PMDs used in these networks.

"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 Gb/s Ethernet over Single-Mode Fiber Task Force. "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."

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