Reference Cord E-2000™ APC, R/1 - FC PC, C/2, G.652.D, 3 m


1 pcs

This reference connector is characterized by a highly precise fiber centricity of G = 0.30µm maximum. To guarantee worst-case measurement, the fibers are turned downward at an angle of ±30°. This means that an optimum measuring precision is ensured, giving you and your customers maximum reliability for each-to-each values of the measured connections.
