1.2. Transceiver PHY Architecture Overview

A link is defined as a single entity communication port. A link can have one or more transceiver channels. A transceiver channel is synonymous with a transceiver lane.

For example, a 10GBASE-R link has one transceiver channel or lane with a data rate of 10.3125 Gbps. A 40GBASE-R link has four transceiver channels. Each transceiver channel operates at a lane data rate of 10.3125 Gbps. Four transceiver channels give a total collective link bandwidth of 41.25 Gbps (40 Gbps before and after 64B/66B Physical Coding Sublayer (PCS) encoding and decoding).
