The CP-1G-RJ45-CB02 is a high-performance Copper SFP transceiver designed for Gigabit Ethernet over Category 5 or better copper cabling . It supports 10/100/1000Mbps operation and provides a maximum reach of 100 meters . The module integrates a full physical layer IC (PHY) that performs 1000BASE-T signalling using 5 level PAM modulation across all four twisted pairs in the cable . The transceiver complies with the SFP Multi-Source Agreement and IEEE 802.3 standards for 1000BASE-T. It supports both SERDES and SGMII host interfaces and offers automatic MDI/MDIX crossover detection.
