From: David Daney The IEEE802. 10GBASE-T makes extensive use of the management functions that may be provided by the MDIO (Clause 45), and the communication and self-configuration functions provided by Auto-Negotiation (Clause 28). The Lumentum 100G CFP2 LR4 optical transceiver is a full duplex, photonic integrated optical transceiver that provides a high-speed link at a 103. Single Lane 10/25/50 Gigabit Ethernet PCS Core The 10/25/50Gbps Ethernet PCS Core is compliant with the IEEE802. RJ-45 1000Base-T I²C Serial Interface µC MDC/ MDIO Figure 1. 3 format frames at 200 Gb/s and 400 Gb/s. Additional OP-code and ST-code for Indirect Address register access for 10 Gigabit Ethernet. 3 Clause 22 and extended in Clause 45. Features 10GBASE-R, 1000BASE-X support on the line interface. Control Interface : I2C and MDIO For most pluggable optical modules the interface used for monitor and control is the I2C interface, also known as the 2-wire interface, however since the advent of the first 10GBase-LX4 Xenpack modules an alternative control interface has also been used, this being the MDIO interface. If your connecting the MAX24287 to a processor, then you need to connect the MDIO to both the MAX24287 and the phy as shown below and configure the registers on both If your using a switch chip, it configures the AN_ADV register to match the MAC mode. 3ae (clause 45). The transceiver electrical interface uses a 104 contact edge type connector, as specified in the CFP2 industry agreement.
