1000SX lan interfaces over cross-over fiber cable ?

[Q4you]

Can we connect 2 1000SX LAN interfaces on 2 systems with cross over connection for data transfer ? normal multimode fibre with LC-LC connectore at each end will work or a special fiber cable is required ?

TIA,

Yes it will work with a standard cable.
You just need to connect RX<->TX & vice versa & IP them on the same subnet.

You probably need to use 2 of the individual cords rather than the duplex so you can cross the TX & RX.

Otherwise should work quite nicely.

Is the interface on this guy fiber?

If so and such an animal exists as a fiber crossover cable, I think you'd need one.

I just swapped some fiber 1000 BaseT for RJ45 ones because I blew the part number on a hardware order.

If its RJ45, why not just try it. The crossover cable costs what $10 US?

Just try it with a fiber cable. I'm quite interested in whether it works or not because have a few idle fiber cards.

Zero point my earlier post. It was mostly mistken. Please zero point this one as well.

I have done this with 100FX with no problems. All that was required was to connect Tx to Rx and Rx to Tx. I haven't used LC connectors though so you may have problems if it is a ganged connector that is keyed so that it can only be plugged in one way.

there is no need for a special cross-over cable with gigabit ethernet. the NICs just figure it out for themselves. copper or fibre.

[Stuart Abramson_2]

Rick Jones is right. You don't need cross-over cables. The NICs figure it out... They're smarter I guess.

So you mean even for 1000BT cards - a crossover copper cable is not required? For SX (Fibre)it might but for BT?

[rick jones]

A cross-over cable is not required for gigabit ethernet - either copper or fibre.

Thanks for your replies.

Here are all the facts :

2 1000SX lan interface cards were connected with standard SC to SC Fiber cable. The rx and tx on a standard fiber cables did not require special configuration. This was done due to very high file xfer requirement between 2 servers ( did not want to load primary IP lan)

The IP configuration is like any other ethernet lan configuration. The max xfer rate over this point to point was appx in the range of 30MB/sec to 80MB/sec.
