SFP-1G-T-BCC | Arista Compatible 1GB Ethernet RJ45 100m (1000BASE-T)

Q: Will this work in place of the Arista SFP-1G-T?
A: Yes. The SFP-1G-T-BCC is a direct replacement delivering the same 1000BASE-T functionality over copper via RJ-45 connector. It is IEEE 802.3ab compliant, operates at 1000 Mbps, and provides plug-and-play compatibility with Arista platforms equipped with SFP ports.

Q: Which Arista platforms support this transceiver?
A: This module works in any Arista switch or router with SFP slots that accept 1000BASE-T copper transceivers. Compatibility depends on the port supporting copper SFP modules; consult the Arista Transceiver and Cable Guide or your platform datasheet to confirm SFP-1G-T support for your specific model and EOS release.

Q: Does this transceiver support auto-negotiation between 10/100/1000 speeds?
A: Yes. The chipset auto-negotiates 10BASE-T, 100BASE-TX, and 1000BASE-T rates depending on the link partner capability. This allows seamless integration into mixed-speed copper networks where legacy 100 Mbps devices coexist with Gigabit endpoints, eliminating the need for manual speed configuration.

Q: Can I monitor link health and temperature using DDM or DOM on this module?
A: No. Copper transceivers with RJ-45 interfaces do not support Digital Diagnostic Monitoring (DDM) or Digital Optical Monitoring (DOM). These features are available only on optical transceivers. Link status and speed can still be monitored via standard Ethernet interface statistics on the host platform.

Q: What is the maximum cable length for 1000 Mbps operation?
A: 100 metres over Cat5, Cat5e, or Cat6 unshielded twisted pair (UTP) cable, as defined by IEEE 802.3ab. This distance assumes compliant cabling and connectors; degraded or non-compliant cable may reduce effective reach. At 10 Mbps and 100 Mbps rates, the same 100-metre limit applies per IEEE 802.3 standards.
