switches and network backbone

By meeva ·
my knowledge of networks is very minimal and would like a solution to the following problem. A private contractor was hired by my company to do 152 points on our LAN. He had been asked to supply a cisco integrated switch so that the fibre cable for the backbone comes from the switch. He instead supplied a cisco 2900 series switch and provided a Dlink transceiver where the fibre was connected. Between the transceiver and the Dlink transceiver is an ethernet link. Is this bound to give us different performance from the one we would have gotten from the integrated switch. The switch is 100mps in speed. I hope i am clear

No difference should be seen.

Many people confuse the potential capacity of the media with actual performance. Fiber at 100 Mbps adds distance and reduces latency versus 100 Mbps, but the latency factor is negligible over any distance suitable for copper. Fiber is the preferred choice when the environment is electrically noisey as well.

The external tranceiver needs to properly mounted to prevent it from becoming a failure point mechanically. Too often these are allowed to place stress on the fiber and copper cables. The power adaptor is another weak point. However, if everything is in a secured cabinet and there is little activity around it then it should work just fine.

You should see no difference in performance. The contactor just gave you what you were asking for in less expensive and efficent way.
