SFP breakout to another SFP

[Stealthrt]

Hey all I am just wondering before I do this if its possible to connect 2 SFP sockets to each other in order to bring in the fiber connection and then take it back out the same way?

So in the image above, Pin 1 would hook up to Pin 1 on the second SFP socket. Pin 2 would hook up to Pin 2 on the second SFP socket, etc etc...

I'm doing this so that I can bring in the SFP connection into a server case and then once inside the server case I need to hook it up to a motherboard inside there that has the SFP connection.

No. Most SFP modules have active electronics in them. They need power and I2C connections to program and enable the optics.

So add a microcontroller and DC power socket?

To better illustrate what I am trying to accomplish:

Get a direct attach cable, and make a small board that has two SFP cages and does a 1:1 match (but swap TD and RD) between the pins on each cage. A direct attach cable implements a TD/RD pair swap, so your board will need to reverse that swap so you can plug in an SFP module. You will also need to provide power to the SFP+. According to the data sheet for a DAC, only the TD/RD pairs are wired, everything else is left open:

Make sure the connections are controlled impedance and routed as differential pairs, the signals passing through are very high bandwidth (1.25 Gbit/s).

Given all the trouble this takes, my suggestion (if you can't re-orient the server board to expose the SFP cage on one edge) is to use copper Ethernet and an external media converter.

thanks radar_macgyver. would you be able to digikey link those things I need?

this is what the ONT fiber hook up looks like that I am wanting to use (green connector).

Why not just couple the fibre in instead of messing around with SFPs?

Have an example from Digikey that you could point to?

How about a keyword: LC-LC coupler. SC-SC coupler. Insert-fibre-termination-here coupler.

To the OP: if you live in North Carolina, RTP/RDU metropolitan, I can fusion splice the fiber for you for free in case you want to take Monkeh's suggestion by passing fiber through a thin hole.

.. no, I mean a panel coupler..

That's even easier. SC-SC couplers are everywhere, even on Amazon. Make sure to spend more money on ceramic based single mode couplers, since your single mode fiber requires better alignment which cheap brass based multimode couplers can not provide.

So something like this?

Exactly. Whack that on your panel, plug your SFP in internally, patch a short piece of fibre between them. Job done.

Nope not in NC. Trust me, I would take you up on your offer if i was

Panel coupler is the way to go, forget everything I wrote

Should just point out: Green suggests it is an Angled SC connector or SC/APC (which would be consistent with it being used on GPON )  so ideally you will need an Angled SC connector and patch leads.
Just checking the vendor you linked to before I can only find an appropriate duplex (two fibre) coupler:

of course there is nothing to say you have to use both sides....
