SFP-10G-ER No Response Whatsoever

[tweep9141983]

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.

Atb,

If you confirmed all the patch correct and no physical issue 100%

try below comand : (bot the side)

interface TenGigabitEthernet1/1/1

speed nonegotiate

[tweep9141983]

thanks for the quick response..
however I just tried.. still no go.. :(

SWITCH1#sh int te1/1/1
TenGigabitEthernet1/1/1 is down, line protocol is down (notconnect)
<SNIP>
!
interface TenGigabitEthernet1/1/1
no switchport
no ip address
speed nonegotiate
end


SWITCH2#sh int te1/0/5
TenGigabitEthernet1/0/5 is down, line protocol is down (notconnect)
<SNIP>
!
interface TenGigabitEthernet1/0/5
no switchport
no ip address
speed nonegotiate
end

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 ?

[tweep9141983]

thanks again! really appreciate it!

Switch --- Fibre----(Provider NTU ?) ----Provider----Provider(NTU)---Switch ? ( is this correct ?) <<<<< CORRECT
- what is the distance between switch and provider NTU ( give other side same ) <<<<< under 3M both sides
- are you using single mode cable ? <<<<< SFP-10G-AOC3M (based on our research this is single-mode
- have you twisted tail end polarity. ( make sure Fibre light travel other side). <<<<< sorry not sure what you mean by twisting? do you mean opposite like below:
1 to 2
2 to 1
instead of
1 to 1
2 to 2

- have you twisted tail end polarity. ( make sure Fibre light travel other side)

here is what i means

Switch  | <<<<-------------Light incoming from NTU -----|  NTU

             |-------------Light  Towerds NTU------->>>>>>|

[tweep9141983]

im really sorry.. i didn't get what you mean.. :(
should i swap ends? see the attached image.. that's the connection right now..

[balaji.bandi]

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.

[tweep9141983]

this is the actual image of the cable we used.

[balaji.bandi]

i am not sure that you got the right cable ? is the Provider suggested this cable?
