Well, I was too curious and opted to open up the PMM 9060 to see if there's some obvious marking in there....
In there is a HFBR-5912EZ transceiver by Avago.
The datasheet is available everywhere and has everthing in it.
So some length of 62.5/125μm or 50/125µm multi-mode fiber with MT-RJ connector it is

Now it's just a matter of finding some source... seems to be pretty exotic nowadays...
