  • 1.  LR SFP's not working

    Posted 03-14-2024 09:52

    We have 1gig Direct connect link terminated on Cienna device and ISP installed a 10gig LR SFP on it. I'm trying to match it on Juniper EX4400-24T switch but interface is not coming up on XE interface.

    With LR SFP I don't even see any LED light coming from SFP connected to Juniper (This makes sense why my first statement is not working). If I insert SFP+-10G-USR  I see light coming from SFP on juniper.  Is there anything to do with LR SFP's and Juniper EX model?
