Cisco GLC-T vs. GLC-TE: A Detailed Comparison for Network Professionals
Selene Gong
Cisco GLC-T and GLC-TE are both 1000BASE-T SFP transceiver modules designed for Gigabit Ethernet connectivity over Category 5 copper wire using standard RJ-45 connectors. They provide a cost-effective solution for short-distance network links, typically up to 100 meters. Understanding their differences is crucial for network engineers and procurement specialists.
The primary distinctions between these modules revolve around their operating temperature range and current product lifecycle status.
The main difference is the operating temperature range and product status. The GLC-T is designed for a commercial temperature range (0 to 70°C) and has been announced End Of Sale by Cisco. The GLC-TE is its proposed replacement and supports an extended temperature range (-5 to 85°C), similar to the SFP-GE-T module, making it suitable for more diverse and less controlled environments. Both support 1 Gbps speed.
Q2.What is a GLC-T?
A GLC-T is a Cisco 1000BASE-T SFP transceiver module that connects to Gigabit Ethernet over Category 5 copper wire using an RJ-45 connector. It operates within a commercial temperature range of 0 to 70°C and is intended for indoor, temperature-controlled settings.
Q3.What is Cisco GLC-TE?
The Cisco GLC-TE is the proposed replacement part code for the GLC-T and SFP-GLC-T modules. It is also a 1000BASE-T SFP transceiver for copper connections but is designed for an extended operating temperature range (-5 to 85°C), allowing for deployment in a wider variety of environmental conditions, including those that are not temperature-controlled.
Q4.What speed does GLC-TE support?
The GLC-TE module supports a transmission speed of 1 Gbps (1000BASE-T). It is purely 1 Gbps only and does not support 10 Gbps speeds.
