[ MODEL-SPECIFIC NETWORK HARDWARE ]
Cisco SFP-10G-T-X 10GBASE-T SFP+ Transceiver
SFP+ module converting a compatible host port to short-reach 10GBASE-T RJ-45. Confirm exact product label and revision before applying specifications.
IDENTIFICATION: Confirm manufacturer PID, hardware revision, device ID or module suffix. Nominal standards/link rates are not measurements of payload performance.
Exact specifications and compatibility
| Dedicated subcategory | SFP transceivers: optical and copper |
|---|---|
| Exact product/model | Cisco SFP-10G-T-X 10GBASE-T SFP+ Transceiver |
| Bus, ports and physical interface | SFP+ host cage; one RJ-45 copper port; Cisco data sheet rates maximum 2.5W at 10G. |
| PHY, radio or protocol | 10GBASE-T; Cisco specifies 10Gb/s over Cat6A/Cat7 up to 30m, and lower 100M/1G modes over specified cable up to 100m. |
| Nominal rate (not measured) | 10Gb/s nominal at qualified short reach; 2.5W module draw and reach are not throughput measurements. |
| Measured throughput | No measured benchmark is claimed for a physical specimen. A valid result must record host/peer, link partner, media/cable, driver/firmware, traffic pattern, test tool and duration. |
| Drivers, OS and firmware | No host NIC driver; Cisco platform firmware must support this high-power copper SFP PID and port thermal envelope. |
| Compatibility | Use only in supported SFP+ cages, short qualified copper cable and adequate host airflow; platform power and thermal limits are critical. |
| Variant warning | SFP-10G-T-X is not standard SFP-10G-T or GLC-T; validate PID, supported rates, temperature and compatible switch/port list. |
Model and revision notes
SFP-10G-T-X is not standard SFP-10G-T or GLC-T; validate PID, supported rates, temperature and compatible switch/port list.
No host NIC driver; Cisco platform firmware must support this high-power copper SFP PID and port thermal envelope.
Use only in supported SFP+ cages, short qualified copper cable and adequate host airflow; platform power and thermal limits are critical.
Archival, ESD and preservation notes
Record module and host temperature/port data. Avoid touching while hot, keep RJ45 clean, and store in ESD-protected case.
Document source URL, access date, document revision and specimen label/condition. Preserve without credentials or private configuration.
