All our polarization-maintaining (PM) single mode fiber patch cables are manufactured in USA. The cables are terminated on both ends with narrow key, ceramic-ferrule FC/APC connectors. Available from stock, these cables feature a high-quality polish, which leads to a typical return loss of 60 dB. Assembled in our facility, each cable is individually tested at the test wavelength listed on the Specs sheet to ensure its extinction ratio and insertion loss at fiber-to-fiber junctions. Each patch cable includes two protective caps that shield the ferrule ends from dust and other hazards.
