1G SFP Copper RJ45 Transceiver – 1000Base-T Electrical Module

SVNK 1GBASE-T SFP RJ45 Copper Transceiver

The SVNK 1GBASE-T SFP Copper Transceiver is a high-performance, cost-effective module designed to deliver reliable Gigabit Ethernet connectivity over standard copper cabling. It is fully compliant with IEEE 802.3 (2002) and IEEE 802.3ab (1000BASE-T) standards, supporting data rates of 1000 Mb/s over distances of up to 100 meters using Cat5/5e/6 unshielded twisted-pair (UTP) cables.

The module supports 1000 Mb/s full-duplex operation using advanced 5-level Pulse Amplitude Modulation (PAM-5) signaling to ensure stable, low-error transmission. Integrated copper PHY technology provides adaptive equalization, echo cancellation, and noise suppression for consistent performance across various cable qualities and installation environments.

The transceiver provides standard serial ID information compliant with the SFP MSA, accessible via the 2-wire serial interface (I²C) at address A0h, while the internal physical-layer IC can be accessed at address ACh. Link status is supported through the RX_LOS pin, enabling seamless integration with standard host systems.

Housed in a compact, hot-pluggable SFP form factor with a rugged RJ45 connector assembly, the module features a fully metallic enclosure to deliver superior EMI shielding and thermal stability. With low typical power consumption (~1.05 W), it is optimized for high-density switching and enterprise network deployments.
