I am trying to find the name of fibre optics cable connector, so a fibre optic cable can be used on my design, does it have a official name? for about the past half hour - an hour I have been googling to find it, but so far have come up with nothing.

Like the connectors used on this internet switch:

Your photo appears to be SFP/SFP+ transceivers.

SFP isn't really a connector type, is a transceiver standard. The actual connector (on the switch side) is a board edge connector, the other side can be a wide variety of connectors.

If it's the actual fibre connector you're talking about, probably LC connector, which is the optical connector used in just about every optical SFP module (LC connectors can be used for both SMF and MMF).

  • \$\begingroup\$ I would like to be able to get a fibre cable, used in internet, and plug it into my design, instead of using ethernet, since what I am designing it for has no ethernet, we use fibre for every thing. Probably being a bit vague, sorry. \$\endgroup\$

  • \$\begingroup\$ @Alex, as long as your signal has balance (ratio of 1's to 0's) and transition density (minimum number of transitions per second) comparable to ethernet, the fiber optic module shouldn't be able to tell the difference. \$\endgroup\$

    \$\begingroup\$ @Alex: if I understand you correctly (your terminology is a bit muddled), you want to connect a board to an Ethernet switch via fibre. In which case you should design an SFP/SFP+ slot onto the board, and then you can use whichever SFP module you wish. However, be aware that designing circuits at these speeds is non-trivial. \$\endgroup\$
