Hope someone can help on this one.
I have some telecom equipment that interconnects a DS-3 signal (~45 MBS) that is having trouble syncing up if I use a coax of around 20 foot length.
The cable tests OK and even works fine in other pieces of equipment. It even works on the suspect equipment, if I loop the signal back to iteslf thru the same coax (effectively doubling the length of the conductor path)
I did some quick and dirty calculations and found out that the wavelength of a 45MHZ signal is approx 21.6 feet.
Is it possible (and probable) that the trouble I am seeing is related to the frequency and length of the coax involved?
I am really stumped to explain this one.
Thanks
