1Gb/s (JT 1G SFP RJ) Copper Small Form Pluggable (SFP) transceivers exhibit high performance and cost-effectiveness. They comply with the Gigabit Ethernet and 1000BASE T standards outlined in IEEE 802.3-2002 and IEEE 802.3ab, supporting a data rate of 1000Mbps for up to 100 meters over unshielded twisted pair category 5 cable. The module enables 1000 Mbps full duplex data links, employing 5-level Pulse Amplitude Modulation (PAM) signals. Additionally, it provides standard serial ID information in adherence to SFP MSA, accessible with an address of A0h through the 2-wire serial CMOS EEPROM protocol. The physical IC can also be accessed via a 2-wire serial bus at address ACh. Features of the 1G Electrical SFP: 1. Supports 1000BASE T operation in host systems. 2. Features RX_LOS for link indication. 3. Designed for a reach of 100m over UTP Cat 5/5e/6 cable. 4. Hot-pluggable with an SFP footprint for convenient installation. 5. Fully metallic enclosure minimizes electromagnetic interference (EMI). 6. Low power dissipation, typically 1.05W. 7. Compact RJ45 connector for ease of use. 8. Access to the physical layer IC via a 2-wire serial bus. 9. Compliance with IEEE Std 802.3-2002. 10. Compliant with Multi-Source Agreement (MSA) standards.
