They also make these for RJ45 stuff. I have a couple I picke up at
BestBuy on closeout. I used to use RJ45 for serial stuff back when it
was more common. I defined a pinout in this form factor that would
allow direct connection of all devices to RJ45 cable without concern
about DCE/DTE due to the swapping in the cable (required that you
install the connecters with a pin1 to pin 8 swap). Then you can just
forget about geneder benders, etc.
I think the RJ45 to RJ45 I had was from Belkin. They can't be too
expensive. I was able to take one apart by separating it at the glue
line. BTW, it did swap pins, so I was able to use it to extend
cables.

I have seen RJ11 gender changers (female-to-female) that are roughly
your dimensions. The end aperture is large enough to hold an RJ45.

Didn't ISDN lines sometimes have an inline terminator between the
phone and the wall, looking like a bulky RJ45-to-RJ45 joiner?

I have put together a little RS232 booster which uses RJ45 connectors
(line powered), around 70 are required, so I am looking for a little
box with RJ45 cutouts at each end. Around 50mm by 30mm. I don't mind
pulling apart somebody elses product but so far have not found
anything appropriate. Just wondered if anybody had any ideas. The case
should cost no more that =A32 ($4).
Thanks
