SFP-10G-T-X-BCC | Cisco Compatible 10GB Ethernet RJ45 30m (10GBASE-T)

Q: Will this work in place of the Cisco SFP-10G-T-X?
A: Yes. The SFP-10G-T-X-BCC is engineered as a direct replacement for the Cisco SFP-10G-T-X and provides identical electrical and mechanical characteristics. It conforms to the same IEEE 802.3an 10GBASE-T standard, SFP+ form factor, and 30-metre reach specification on Cat6a or Cat7 cabling. The module is plug-and-play compatible with Cisco platforms and auto-negotiates link speed with any 10GBASE-T endpoint.

Q: Which Cisco platforms support this module?
A: This module is compatible with Cisco switches and routers featuring SFP+ ports that meet the 2.5W per-port power budget requirement. Note that the SFP-10G-T-X has higher power consumption than optical SFP+ transceivers, which may limit the number of ports you can populate simultaneously on certain platforms. Consult your specific Cisco platform datasheet for power budget and port density limitations when deploying 10GBASE-T modules.

Q: What cable type is required to achieve 10Gbps at 30 metres?
A: Cat6a or Cat7 cable is required for reliable 10Gbps transmission at 30 metres. While IEEE 802.3an permits 10GBASE-T on Cat6 up to 55 metres under ideal conditions, real-world Cat6 installations often fail to meet the tolerance due to alien crosstalk and termination variability. For guaranteed 10Gbps performance at the module's rated 30-metre reach, specify Cat6a or Cat7 cabling and verify the run with a Cat6a-capable cable tester before commissioning.

Q: Does auto-negotiation support intermediate speeds like 2.5G and 5G?
A: Yes. This module supports IEEE 802.3bz multi-gigabit Ethernet, enabling auto-negotiation at 2.5Gbps and 5Gbps in addition to 1Gbps and 10Gbps. The module will automatically select the highest common speed supported by both link partners. This is useful for connecting to Wi-Fi 6 access points with 2.5G uplinks or NAS devices with 5G interfaces. Some switch platforms may require the SFP+ port speed to be manually configured to match the remote device, so verify behaviour against your switch firmware release notes.

Q: Why does this module run hotter than optical SFP+ transceivers?
A: 10GBASE-T modules consume significantly more power than optical SFP+ transceivers due to active copper PHY signal processing. The module implements advanced equalisation, echo cancellation, and crosstalk mitigation across all four twisted pairs to achieve 10Gbps over copper. This processing requires up to 2.5W per port compared to under 1W for optical SFP+ modules like 10GBASE-SR. The module operates within a -5 to 85 degrees Celsius range and relies on adequate switch chassis airflow to maintain thermal stability. Ensure your deployment environment provides sufficient cooling, particularly when populating multiple ports.
