4900M Twingig Converter Module / SFP

[wrgu]

Hi there,

I am little confused with all these SFP types.

Can I use GLC-LH-SM, GLC-LH-SMD and SFP-GE-L with Twingig converter module? When I used Cisco configuration tool, the only option is GLC-LH-SMD for 1000BASE-LX.

Thanks,

End-of-Sale and End-of-Life Announcement for the Select Cisco Gigabit Ethernet SFP Modules

Any SFP that ends with a "D" means it supports Digital Optical Monitoring (DOM). 

SFP-GE-L is similar to GLC-LH/LX but is not supported on the 4900M. or TwinGig converter.

You need also consider that base 4900M chassis does not support TwinGig converters.
