The document provides specifications for fiber optic adapters and patch cords. It lists insertion loss and return loss specifications for singlemode APC, singlemode UPC and multimode PC adapter types. It also specifies an operating temperature range of -40°C to 80°C and less than 0.1dB change in insertion loss from 10Hz to 55Hz vibration. Wavelengths of 850nm for multimode and 1550nm for singlemode are supported. Application areas include telecommunications, access networks, data transmission and test equipment. Features include low insertion loss, high return loss, temperature stability and easy connectivity.
