Arista SFP-1G-T-Arista | 1G SFP Transceiver, Copper RJ-45, 100m, 1000BASE-T

Q: What is the difference between the SFP-1G-T and a fiber SFP module?
A: The SFP-1G-T is a copper transceiver that uses an RJ-45 connector for standard Ethernet cabling (Cat5/Cat6) up to 100 meters, while fiber SFP modules use LC or SC connectors for longer-distance connectivity over single-mode or multi-mode fiber. Copper transceivers are ideal for shorter runs and cost-effective campus or building deployments.

Q: Is the Arista SFP-1G-T compatible with other vendor switches?
A: This module is programmed specifically for Arista switches and routers. While it follows MSA (Multi-Source Agreement) standards, compatibility with non-Arista equipment depends on whether the host device accepts third-party or vendor-specific transceivers. Always verify compatibility with your specific platform.

Q: Can I use Cat5 cable with the SFP-1G-T for Gigabit speeds?
A: Yes, Cat5 cable supports 1000BASE-T Gigabit Ethernet up to 100 meters. However, Cat5e or Cat6 is recommended for optimal performance, especially in electrically noisy environments or for future-proofing your infrastructure.

Q: Does this transceiver support auto-negotiation?
A: Yes, the SFP-1G-T typically supports auto-negotiation for speed (10/100/1000 Mbps) and duplex mode, allowing seamless interoperability with devices of varying capabilities on the same network segment.

Q: What is the typical power consumption of the SFP-1G-T?
A: Copper SFP transceivers like the SFP-1G-T typically consume between 0.8W and 1.5W, which is higher than most fiber SFP modules. Ensure your switch has adequate power budget per port, especially when using multiple copper SFPs in high-density configurations.
