This post is updated on Nov.17, 2022. We hope keep the content always fresh.
GLC-T, SFP GE-T, and GLC-TE are major types of 1000BASE-T SFP copper transceiver. All of these products are compatible with same types of cables, including copper cables up to 100 meters (5 unshielded). These models also support auto-negotiation with MDIX and MDI Auto. What are their similarity and differences? Many IT professionals may be confused. We will make a comparison on those 3 1000BASE-T SFP modules.
GLC-T SFP Module
The GLC-T is referring to 1000BASE-T Small Form-Factor Pluggable (SFP) Gigabit Interface Converter. It is a hot-swappable I/O device that plugs into Gigabit Ethernet ports or slots to connect ports to the network. This 1000BASE-T SFP provides full-duplex Gigabit Ethernet connectivity for high-end workstations and wiring closets over the existing copper network infrastructure. The 1000BASE-T SFP operates on standard Category 5 wiring of up to 100m link length.
SFP-GE-T SFP Module
The SFP-GE-T is 1000BASE-T SFP transceiver module for Category 5 copper wire, extended operating temperature range, RJ-45 connector. It is NEBS 3 ESD grade.
GLC-TE SFP Module
The GLC-TE is referring to 1000BASE-T SFP extend temperature transceiver module for Category 5 copper wire, RJ-
Comparison: GLC-T vs SFP-GE-T vs GLC-TE, What is the similarity and difference?
Now let us make a comparison of the similarity and difference on GLC-T vs SFP-GE-T vs GLC-TE, it will help you choose right 1000BASE-T SFP module for your Gigabit Ethernet switches.
| Models / Specs | Data Rate | Fiber mode | Standard | Distance | Connector | Operating Temperature | Note |
| GLC-T | 1G | Copper | 1000BASE-T | 100 m | RJ45 | Commercial 0~70°C | |
| SFP-GE-T | 1G | Copper | 1000BASE-T | 100 m | RJ45 | Extended -5~85°C | NEBS 3 ESD |
| GLC-TE | 1G | Copper | 1000BASE-T | 100 m | RJ45 | Extended -5~85°C |
We can learn the similarity from the above specs comparison, the similarity is all the three 1000BASE-T SFP support same data rate, same connector, and same distance, and with the same SFP form factor. The difference is the operating temperature and ESD, that is for different application.
Based on the different features, GLC-T usually target on general copper networking application and with the lowest pricing, while the SFP-GE-T and GLC-TE is for some industrial networking applcation and with b bit higher pricing.
What is NEBS 3?
NEBS is the abbreviation for the Network Equipment Building System, a set of technical requirements with one basic purpose: to make network switches bulletproof. NEBS Level 3 means the device is on a remote network. We are talking about this strict level of telecommunications. The device will operate in the extreme environment found in the central office. In short, the device meets all the requirements of the GR-63-CORE and GR-1089-CORE.
Conclusion
After the comparison, have you know the difference between GLC-T vs SFP-GE-T vs GLC-TE? Do you know how to choose the right 1000BASE-T SFP module? In fact, it depends entirely on your actual needs.
