Cisco Transceiver Module: GLC-T vs GLC-TE

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.

GLC-T Datasheet

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.

Description
1000BASE-T SFP transceiver for CAT5 wire, RJ 45 connector
Max Data Rate
1000Mbps
Max Distance
100m
Operating Temperature
0 to 70°C (32 to 158°F)
Commercial Availability
Announced EOS by Cisco and has not been available for sale since June 1, 2011

GLC-TE Datasheet

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

Description
1000BASE-T SFP transceiver for CAT5 wire, RJ 45 connector, extended temperature
Max Data Rate
1000Mbps
Max Distance
100m
Operating Temperature
-5 to 85° (23 to 185°F)
Commercial Availability
New product and will continue to be sold for years.

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.
