FTB-1 mainframe and FTB-720-23B-EA.

I spliced a new fiber on the OTDR and is good as new. See reflectivity of .2dB.

OTDR tested with 70km of SMF and DS fiber.

iOLM license is there, not the old style OTDR.

FTB-880 has 1 port SFP+ that could test 10GbE transceivers. See photos for licenses on unit.

Two modules included. OTDR and Traffic test.
