GigaTech SFP-10G-T-GT & Cisco SFP-10G-T-X
Performance Comparison Guide
The GigaTech SFP-10G-T-GT solution was introduced in 2017, over 2 years before Cisco introduced their SFP-10G-TX. Due to the extended duration of use over time, the GigaTech solution has a proven track record for superior durability and compatibility in countless networks. The GigaTech and Cisco options utilize the same form factor and comparable chipset and design, however there are some key differences and advantages to using the GigaTech solution over Cisco’s.

GigaTech SFP-10G-T-GT | Cisco SFP-10G-T-X |
- Compatible with all Cisco devices which accept 10G SFP+ DAC. No compatibility issues or constraints.
- Only supported in limited systems and must adhere to specific port configurations.
- Introduced in 2017, 2 years before Cisco. Longer history of compatibility and durability testing.
- Introduced in 2019. Abbreviated history of use.
- Requires no initial port configuration, plug and play. Compatible with default “Media-Type 10G-Tx” setting.
- Requires unique port configuration “Media-Type 10G-Tx” command enabled. Will not work without the port being set.
- Does not alter or limit neighboring ports power consumption. Recommended port spacing between 10G-T transceivers to ensure system power limitations and airflow.
- Limits neighboring even numbered ports to 0.1W max power consumption (allowing only SFP-H10GB-CUxM cabling to be used in sub slots nearby, no optical transceivers or other media.)
- 2.3W Max Power Consumption
- 2.5W Max Power Consumption
- Displayed as unsupported or invalid if “Media-Type 10G-Tx” is enabled.
- Displayed as unsupported or invalid if “Media-Type 10G-Tx”is disabled (command not applied).

Deployment Scheme
GigaTech SFP-10G-T-GT
The following figure shows the maximum configuration density of SFP-10G-T-GT SFP+ transceivers for this switch
Active Port deploying the SFP+ 10GBASE-T transceiver. While the GigaTech SFP-10G-T-GT transceiver does not actively disable any port configuration or require initial setup, it is recommended to use port spacing between each deployment to ensure limited power consumption, and maintain efficient airflow of the host device. There should never be over half capacity loaded into the same networking device to ensure full functionality.
No limitation to neighboring ports. Open to use any transceiver type – Optical SFPSFP (Small Form-Factor Pluggable) is an optical transceiver standard that supports 10Base/100Base/1000Base and 1G/2G/4Gbps Fibre Channel data transmission rates, and is hot pluggable. SFP transceivers connect network devices to Fibre Channel and Gigabit Ethernet (GbE) fiber optic cables through an integrated dual-LC optical connector. Click to Read More, DACDirect Attach Copper (DAC) cables use a passive twinax cable assembly with SFP+ transceiver housings built onto each end. These cables are typically available in lengths from 1 meter to 10 meters. DAC cables utilize little power, are low cost but do have bulkier (larger diameter) cables than fiber optic alternatives. Click to Read More, AOCActive Optical Cables (AOCs) are specialized cables which make use of electrical-to-optical conversion circuits (transceivers) on each end of the cable. Click to Read More.
Cisco SFP-10G-T-X
The following figure shows the maximum configuration density of SFP-10G-T-X SFP+ transceivers for this switch
Active Port deploying the SFP+ 10GBASE-T transceiver, with max power consumption up to 2.5W. Once configured with “media-type 10g-tx” in NX-OS or “Link Level Policy > Physical Media Type > SFP-10G-TX” in ACI, these ports can deploy SFP-10G-T-X. Without such configuration, they behave like normal ports.
Port Shutdown or Active with Passive Copper Cables only (Max power consumption up to 0.1W). Once 10g-tx is congifured on yellow ports, ports to the left, right, top, and bottom of the yellow ports are referenced as the blue ports. These adjacent ports will then support only low power Passive Copper DAC cable, or these can be left empty to conserve power. If 10g-tx configuration is removed from adjacent yellow ports, the blue ports will revert to behaving like normal.
