Bi Di Carrier Circuits Mapping to 1 Interface on my End Device

[jethro66]

I have two End Devices in two different Data Centres (20km Apart) that are connected together using Single Mode Fibre directly supplied by a Carrier. The service is supplied with two individual dark fibre cores, there is nothing in between. Just so we're all clear......this service is just a very long patch lead between two devices :-) Here's the bit that opens Pandorra's box for me in Netbox though......Each core has it's own Circuit ID !!!!

So by having two Circuit ID's associated with this connection, but only one interface at each end device, how do I do this ??? Am I overthinking the simplicity of this ? BTW ..... I'm using Netbox V3.6.1

Each single fibre core is a circuit, and I can connect each end ("A" and "Z"), of each circuit, to a "termination" point, ie a FOBOT Panel's Rear Panel Connector to then be patched through to the End Device's Port....BUT.....I can only use that End Device's Interface once, so where do I connect the second Circuit ID ? If I patch the second circuit to another Rear Panel Connector (which I have done), at some stage both the individual cables representing each circuit need to merge into "one" cable feeding the End Device's singular SFP Interface as represented in Netbox.

I thought of having a TX and an RX Interface on the End Device, but that would open Pandorra's box on IPAM management....and I'm sure a lot of other problems that I haven't even thought of yet ? What am I doing wrong please ?

Closing this Thread because I discovered that you can patch a two separate Interfaces to a Single Interface in Netbox. However I still haven't worked out the second half of my problem with Carrier Circuits and mapping. Opening up a new Query. Hopefully someone will respiond

Hi Jethro66,
we did it like in the ling to the image, may be this is how you can do it, assuming you also have Patchpanels inbetween.

Thankyou for your reply. I finally worked this out myself late last week....well, half the problem that I had with splitting cables, but the second part of my problem still eludes me :-) . I've opened a second query #19079 , about having two carrier circuits. These two carrier circuits would be like your diagram above, but replace Cable "284" with one Circuit ID and then replace Cable "285" with the other Circuit ID
