GLC-T Vs SFP-GE-T

[yezawkhant]

May I know what is the differences between GLC-T and SFP-GE_T?

What I found out through net are as follows :

GLC-T

1000BASE-T SFP RJ45 100m transceiver

Specifications

• Form Factor: SFP
• Device Type: Transceiver module
• Connectivity Technology: Wired
• Wavelength: n/anm
• Max Distance: 100m
• Data Transfer Rate: 1Gbps
• Fiber Type: n/a
• Connector: RJ45
• DDM: Without DDM
• Operating Temperature: 0~70 °C
• Application: 1000BASE-T
• Compliant with MSA SFP Specification

SFP-GE-T

• 1000BASE-T SFP RJ45 100m optical transceiver

Specifications

• Form Factor: SFP
• Device Type: Transceiver module
• Interface (Bus) Type: Plug-in module
• Connectivity Technology: Wired
• Application: 1000BASE-T
• Data Transfer Rate: 1Gbps
• Wavelength: n/anm
• Max Distance: 100m
• Fiber Type: n/a
• Connector: RJ45
• DDM: Without DDM
• Operating Temperature: 0~70 °C

So no difference between them?

I need tranceiver module to install on my 2960S and 3750E swithces, of course RJ45 copper wire (Gigabit Eternet).

GLC-T is what you need to order.

Why?

Do SFP-GE-T support various data transfer rate? Say 10 Mbps, 20Mbps or 100 Mbps?

20 Mbps?  NO.  I've never heard of a client who's not following standards.

10/100Mbps will depends in your platform and your IOS.

If you stick the SFP into a 6500, for example, the module will operate in 1 Gbps.
