The OLC-AF, attenuation reference fiber is designed for the calibration of the attenuation scale of SM OTDR. The OLC-AF is wind from defined length of G.652 Single mode fiber or OM2 Multimode fiber.
The OLC-AF consists in a fiber spool of a defined attenuation at required wavelength, which is installed in a thermally shielded rack mount optical distribution frame for better stability. The reference fiber is fitted with two APC connectors for single mode and PC connectors for multimode. The attenuation is calibrated at 1310 nm for SM or at 850 nm for MM.
