How to pad a switch for a fiber connection?

I work for a park district and we recently completed a fiber project where we ran fiber cable through our lake and land to connect our 3 buildings to our 1st building where our two t1's come in. After the company trenched and installed the fiber cable, they said the signal from end to end was moving too fast and our equipment (switches both POE and NON) needed to be "padded" to slow down the signal.

Does anyone know how to do this and what it means? we purchased DLINK switches (DES-3010pa, DES-3010GA, AND DES 1228P) I have included a fiber map of how many strands were installed and where. Thanks MJD

I woudl like to know how light can travel to fast?? as I under stood light travels at a faily constant speed!

as for padding I am not sure what they mean, I have laods of fibre around site from 10 meters to several Km and I have never needed to "PAD" a link??

I am assumign it is something to do with the frequency of the signels rather than the speed, maybe the splices are causing interference to the signel and you need to reduce that.

however the onyl thing I can think of is to reduce he speed from say gig to 100mbs?

or insue all ends fo the linsk are hard coded to run at the same speed.

All the installers told me was the signal was moving too fast from building A to building B and I needed to pad the equipment that was to be installed.

I know that when testing fibres you sometimes need to insert a long (5km+) piece of fibre to smooth the signel out and give you a accurate reading, as with a short lenth the responce times are so fast the testing equipment is not accurate. maybe this is what they mean.

but to be honest i still think there termonology is wrong. laws of physics say speed of light is a set value!
