Hi Everyone,
It's my first time to use this SFP and at the moment, I am having no luck. For more information, below are the hardware and scenario.
Site 1:
Switch: C9300-48T
Module: C3850-NM-4-10G
SFP: SFP-10G-ER
Cable: SFP-10G-AOC3M
Site 2:
Switch: C9500-16X-A
Module: C3850-NM-4-10G
SFP: SFP-10G-ER
Cable: SFP-10G-AOC3M
Site-to-Site Distance is only 20Km
Configs:
Switch1 - C9300-48T
!
interface TenGigabitEthernet1/1/1
no switchport
no ip address
end
Switch2 - C9500-16X-A
!
interface TenGigabitEthernet1/0/5
no switchport
no ip address
end
Metro-Link already tested by PROVIDER end-to-end and confirmed working. I can confirm no issues with them, as I was there during the testing. I reckon the issue is on our end, possibly configuration or (I really hope not or I'm dead) incorrect hardware. In previous experiences with Modules and SFPs (1Gig) , they are straight-forward and no special config.. as long as you setup the interface, connect the fibre cables, LED lights come-up and interface status goes up up.. however today, no luck.. even no lights and no logs showing on both switches when I plug-unplug the fibre cable.
Also attached are some pics for more information.

Ok now we need to get in to more details here.
Can you explain how the setup here ?
Switch --- Fibre----(Provider NTU ?) ----Provider----Provider(NTU)---Switch ? ( is this correct ?)
- what is the distance between switch and provider NTU ( give other side same )
- are you using single mode cable ?
- have you twisted tail end polarity. ( make sure Fibre light travel other side).
Can you post
show interface XX trans details.
Other test you can do is - connect any other device locally see if the port come up or not ?

here is what i means
Switch | <<<<-------------Light incoming from NTU -----| NTU
|-------------Light Towerds NTU------->>>>>>|

white or gray fibre lead swap over, try one side if the link come up or not, if link come up ok, if not do same on the far end also.
