Master Patchcord
Master optical patch cord are required for testing in optical networks, calibration services and for manufacturing fiber optic components. A master patch cord is terminated by master connectors that fulfill the strict demands on geometrical and transmission parameters according to defined specifications.
Feature
In accordance with EN, IEC and CEI 61754 standards
Low insertion loss and high return loss
Excellent end face geometry parameters
Variety of connector types: FC, SC, ST, MU, LC
Customized order available upon request
