Pardon my ignorance in this area but is too much to ask for OTDR data before signing contracts? In addition to data on the make of the fiber if you wanted to do xWDM in the future.
fibre grade / quality, absolutely. otdr is difficult, because fibre providers usually splice up a specific path for a specific order. This means that they cannot always provide the otdr without first going to some trouble and expense. So you may find yourself having to specify acceptable attenuation limits in advance, then putting in an order and then getting the otdr + accurate attenuation results after the order has been accepted. Obviously, you assume some risk in terms of hoping that the optics that you buy for the circuit will actually do the job. Nick
