For switch to server connectivity with fiber cable:

  1. TX end connected of server will be connected to the TX of the switch and vice versa.

  2. To validate the TX end, see through the cable. The one with light is TX end.

Please confirm my understanding. Also suggest if i need to check anything else.

You should never (ever) look into a fiber cable with equipment (lasers) attached to it. You can severely damage your retina. Use a flashlight in one end to check if you have the pairs correct.

TX on one side goes into RX on the other side and vice versa.

  • what if i need to connect two brocade switches. In that scenario also TX should go to RX and vice versa? Fiber optics doesnt works like Ethernet ? In ether net we connect switch by Straight cable to server. – user57218 Oct 15 '10 at 14:00

    Fiber optics have one pair of "cables", one for each direction of light. Yes, the same rules apply. TX in one port is connected to RX at the other side. – pauska Oct 15 '10 at 14:02
