Catalyst 3750 SFP Transceiver

I am trying to figure which port is fiber sfp and which port is copper sfp. I have a 3750 WS-C3750X-48P-S.

...
Gi1/0/5                      connected    trunk      a-full a-1000 unsupported
Gi1/0/9                      connected    trunk      a-full a-1000 1000BaseSX SFP
Gi1/0/10                      connected   1          a-full a-1000 10/100/1000BaseTX SFP
Gi1/0/11                    connected    1          a-full a-1000 10/100/1000BaseTX SFP

I know that gig1/0/5 is a non-Cisco sfp sx transceiver
I am not sure about gig1/0/9-gig1/0/11. Is that a copper sfp transceiver? If yes, then is then an actual sfp transceiver in there?

The answer:
Gig1/0/9 is a fiber SX transceiver
Gig1/0/10 - 11 are copper transceivers

Yes they are actually there otherwise the ports would not show anything.

How to connect Cisco 3750 with fiber?

What SFP module would you use to connect a 3750 switch WS-C3750X-48P-L to a 3550 that is using a WS-G5486 Gigabit module? Does anyone have experience with SX to LX adapters and if they are reliable?

The answer:
You would need to use a GLC-LH-SMD transceiver for this, and a LC-SC single-mode patch cord (if they're being connected directly without an intermediate patch-panel).
They are very reliable and are used for long links, well over the length that SX modules can go.

Catalyst 3750 is next-generation energy-efficient Layer 3 Fast Ethernet stackable switches while 3750X is layer 3 GE switches. The Cisco Catalyst 3750 v2 Series consumes less power than its predecessors 3750. The 3750-X Series Switches are enterprise-class lines of stackable and standalone switches with StackWise Plus technology, they are the replacement of Cisco 3750G and 3750E switches. 3Anetworkcom keeps many stocks for 3750V2 and 3750X switches. Among all Cisco Catalyst 3750 switches, WS-C3750V2-24TS-S and WS-C3750X-24T-S are best selling models. 3Anetwork.com offers best Cisco 3750 Price, Cisco 3750V2 Price, Cisco 3750X Price, ship to worldwide.
