HI TO ALL...I WOULD LIKE TO ASK THE FOLLOWING QUESTION. I HAVE A 48 PORT HP PROCURVE SWITCH THAT NEEDS TO BE CONNECTED WITH A 24 PORT HP PROCURVE SWITCH USING A GIGABIT SFP MODULE.THE OPTICAL FIBRE PATCH CABLE IS 62 AND A HALF MULTIMODE SC-LC CONNECTOR TYPE CABLE.THE SFP MODULE HAS A TRANSMITTING AND RECEIVING CHANNEL.MY QUESTION IS : THE PATCH CABLE SPLITS INTO TWO MARKED A AND B. WHICH CABLE IS FOR TRANSMITTING AND WHICH FOR RECEIVING? OR CAN BOTH CHANNELS BE USED FOR EITHER? THANKYOU VERY MUCH

Thanks. We'll let you know when a new response is added.

One fiber is for transmitting, the other for receiving, but it doesn’t matter which does which — “transmit/receive” is going to be different from each switch’s point of view anyway, isn’t it? All you need to do is make sure you have one switch’s TX connected to the other’s RX and vice versa. You can’t damage anything by plugging it in wrong, it just won’t work, so go ahead and try it — you have a 50/50 chance of getting it right the first time!

<i>You should also take care about the fact that you may change fibers on patch cable or in patch panel to make cross-connection. The used light can also make problems if you have different wavelenths on Tx and Rx side. Just be aware of that possible problem. Good luck! </i>
