Description

The Arista SFP-10G-T is a 10GBASE-T copper transceiver module designed for high-speed data center and enterprise network connectivity. Featuring an RJ-45 interface, it delivers 10 Gigabit Ethernet performance over Cat6a or Cat7 copper cabling up to 30 meters, ideal for intra-rack and adjacent-rack connections. This hot-swappable SFP+ transceiver supports multi-rate auto-negotiation (10G/5G/2.5G/1G) and is compliant with IEEE 802.3an, IEEE 802.3az, and SFF-8431 standards for seamless integration with Arista switches and routers.

FAQs

Q: What cable types are compatible with the Arista SFP-10G-T?
A: The SFP-10G-T is designed for use with Cat6a or Cat7 Ethernet copper cables. While Cat6 may work for shorter distances, Cat6a or Cat7 is recommended to reliably achieve 10 Gigabit speeds over the full 30-meter reach and ensure compliance with IEEE 802.3an specifications.

Q: Does this transceiver support speeds other than 10 Gigabit?
A: Yes, the SFP-10G-T supports multi-rate auto-negotiation and is backward compatible with 1000BASE-T (1G), 2.5GBASE-T (2.5G), and 5GBASE-T (5G) standards. This allows flexible deployment with various endpoint devices including NAS systems, Wi-Fi 6 access points, and multi-gigabit network interface cards.

Q: What is the typical power consumption and thermal profile?
A: The SFP-10G-T typically consumes approximately 2.5W, which is higher than optical SFP+ modules due to active signal processing, equalization, and echo cancellation across all four copper pairs. Adequate airflow is required to maintain the module within its 0°C to 70°C operating temperature range.

Q: Is the SFP-10G-T compatible with all Arista SFP+ ports?
A: The SFP-10G-T is supported on all Arista SFP25 ports and select SFP+ ports. Arista also offers the SFP-10G-T-RP variant with lower 1.5W power consumption that enables broader compatibility across all Arista SFP+ and SFP25 ports. Refer to the Arista Transceiver and Cable Guide for specific platform support details.

Q: What are the primary use cases for copper 10GBASE-T transceivers?
A: The SFP-10G-T is ideal for short-reach connections within data center racks, adjacent rack interconnects, top-of-rack to server connectivity, and enterprise wiring closet deployments where existing copper infrastructure can be leveraged. It provides a cost-effective alternative to fiber optics for distances up to 30 meters while reusing Cat6a/Cat7 cabling.
