Hi, I’m looking for a tester that can preform a RFC2544 test at 1GB SM, I was looking at the  
Jonard Tools - OTDR 1000, however the data sheet is unclear about support for this test.

Hi,  
Welcome to the Digikey tech forum. I’m not familiar with RFC 2544 testing standards but after reading about it and looking at part OTDR 1000 I would say it does not have the capabilities to perform the subtests listed in RFC2544 standards. I didn’t find any options to offer for this but like I said I’m not really familiar with this, perhaps someone with more experience in this field can pitch in here.
