Cisco SFP transceiver modules have become exceedingly popular with the widespread of Cisco routers and switches. GLC-T and GLC-TE are the two types of Cisco SFP transceiver module. Since the name GLC-T and GLC-TE are quite similar, many end users may be confused. So are they the same one? Here we’ll focus on GLC-T vs GLC-TE to help find the answer.
Cisco GLC-T SFP is a 1000BASE-T Small Form-Factor Pluggable RJ45 interface converter. It can be inserted into Gigabit Ethernet ports to connect ports to the network. GLC-T SFP transceiver provides 1Gbps data transmission. Besides, it supports the full-duplex Gigabit Ethernet connection for the high-end workstation. Operating on CAT5 cables, this SFP transceiver is designed with the max cable distance up to 100 meters. However, GLC-T has not been on sale since June 1, 2017. The following is the GLC-T datasheet.

Max Data Rate
0 to 70°C (32 to 158°F)
Announced EOS by Cisco and has not been available for sale since June 1, 2011
GLC-TE transceiver is also a Cisco SFP module that designed for Gigabit Ethernet applications. It’s compatible with the IEEE802.3 1000BASE-T standard. It’s the replacement model of GLC-T, which means GLC-TE is an improved technology product. Therefore, this transceiver is designed with the same features of GLC-T type but has an extended temperature range from -5 to 85°. GLC-TE is the latest in technology and definitely will continue to be sold for years. The table below shows GLC-TE datasheet.GLC-TE Datasheet

GLC-T vs GLC-TE: Difference and Similarity
- Difference. From the above, we can clearly know that the main difference between GLC-T vs GLC-TE is the operating temperature. This means GLC-TE can work in a lower or higher temperature environment without any damage.
- Similarity. Both GLC-T and GLC-TE are 1000BASE-T copper transceivers that comply with IEEE 802.3 standard. They support the same data transmission speed and cable distance via CAT5 copper cables. However, considering that GLC-T SFP transceiver has stopped production, GLC-TE is the best choice.
In addition, as for GLC-T vs GLC-TE, there are many similarities except for operating temperature. The two SFP transceivers can be used in the following cabling system.
