Cisco GLC-T Compatible 1000BASE-T SFP Transceiver Module (Copper, 100m, RJ45)
This Cisco GLC-T compatible SFP module supports 1000Base-T connectivity up to 100m (328ft) over Cat5/Cat5e or above Ethernet cable via RJ45 connector. It is a copper transceiver compliant with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE 802.3-2002 and IEEE 802.3ab. Instead of an OEM supplier, it is made by a third-party manufacturer, OPTCORE. Hence, it offers a very affordable price when compared with the original GLC-T. Most importantly, we code and test each transceiver to ensure it works with the Cisco 1G network switches, routers, servers, and network interface cards (NICs).

Keith –
This module does the job well but it is very affordable. There is no point in buying “brand name” optics when you can get this one at a mere fraction of the cost. I absolutely no issues installing the SFP into my Cisco 3750-G. highly recommend it.
Null –
Seems to be working with my Jetstream smart switch at 1Gbps. I Will update if there are issues.
Estanis –
I have a 3750x switch in my network. The copper modules worked with it no issues. Price was cheap. I recommend this SFP and will buy again if I need it.
Helen –
Can be used on PaloAlto devices, but does not know the reliability.
Britta –
I have bought a lot of optical modules. So I can judge the quality once get, this GLC-T is definitely a high-quality product.
Demian –
This time I bought a lot of rj45 SFP and used it for my company’s projects. The delivery was very fast. I received the optics on time and put them all into use. The project was successfully completed. The project manager said that the product is very good, plug and play, good compatibility, super good products.
Bruce –
The mini GBICs was delivered quickly and worked as specified.
