CRS125 + S-31DLC20D /

Hardware MikroTik hardware general
1

Ive got a pair of cloud router switches Im trying to get a fibre link between them.

Both ends have S-31DLC20D, and Ive got a LC patch cable (so TX and RX reversed end to end)

One end I’m using a CRS225 and its seeing the module, plus when the patch is in to the CRS125 it says the links up

The CRS125 end, its showing the module, but says no link, but its all populated.

If I remove the fiber from the CRS125 the CRS226 looses link

So it seems its working only one way. I’m seeing packets leaving the 226 and nothing in or out the 125

Yes Ive swapped modules the fault remains with the 125

Any ideas?

Ive not assigned any IPs yet and both SPF are still slaves to the master ether 1

sfp tab of interfaces on crs 226 and crs 125 shows something??

i have access to a CRS125 wothout sfp module and shows this:

Yes it shows serial numbers, ids, wavelengths, range and so on.

Both ends..

But the link is only active on the 226 and I only see TX bytes
The 125 shows no link and no I/C or O/G

Its like the lazer is disabled or something both ways the 125 end

But swapping modules the 125 still down.

Resolved :slight_smile:

I set Ethernet each end manually to 1GB and its locked and TX / RX both ends :-0
