Amendment to IEEE Std 802.3-2005 This amendment to IEEE Std 802.3-2005 specifies a new PMD, 10GBASE-LRM, for serial, 10 Gb/s operation over up to 220 m of 62.5 µm and 50 µm multimode fiber, including installed, FDDI grade multimode fiber

The scope of this project is to specify additions to and appropriate modifications of IEEE Std 802.3-2002 as amended to add a Physical Layer (PHY) for operation at 10 Gb/s on standards based structured fiber cabling, using the existing MAC and with extensions to the appropriate physical layer management parameters of IEEE Std 802.3.

This project will define a lower-cost, 10Gb/s serial PHY that supports a link distance of at least 220m over installed FDDI-grade multimode fiber. The specification should enable migration to smaller form factor pluggable modules.
