[pminguy]

i have a port adapter nm-1a-oc3-pom with a sfp-oc3-mm i need sm sfp. May i use a 1000base-lx sfp instead ?

Hi,

You can not use the 1000 base-lx sfp on this module.

Following are the supported SFPs -

SFP-OC3-MM

SFP-OC3-IR1

SFP-OC3-LR1

From this compatibility doc - http://www.cisco.com/en/US/docs/interfaces_modules/transceiver_modules/compatibility/matrix/OL_6980.html

If you want the sfp to support a higher distance then look at IR (15km) or LR (40km) SFPs mentioned above.

Hello Pierre,

as explained by Sushil you need specific SFP, because a 1000 base lx is designed for gigabit ethernet so they use different line codes and modulations techniques.

Hope to help
