ULTIMODE PC-522D1 is made of two parallel sections of single-mode fiber optic cable with a length of 1.5 meter, each terminated with SC/APC connector. SC connectors are currently the most popular optical coupling elements due to simple matching (push-pull coupling with a snap), rectangular cross-section allowing dense packing of the connectors on the panel, and plastic construction (of course outside the ferrule). SC/APC connectors, due to stepped end style APC ferrule (8 degrees), ensure return loss >50 dB so that they fulfill higher requirements for signal transmission.

ULTIMODE patch cords are characterized by low attenuation and back reflection (reflectance). They use highest quality ferrules. Each patchcord passes individual quality control (inspection of surfaces and measurement of transmission parameters - insertion and return loss).

The single-mode optical fiber with low water peak used in the patch cords is compliant with ITU-T G.652.D standard. It provides full compatibility and ability to perform quality splices with existing fiber-optic networks. The average attenuation of the fiber is about 0.4 dB/km for 1310 nm, and 0.25 dB/km for 1550 nm. The optical fiber is reinforced by aramid fibers (Kevlar) and covered with PVC sheath.

The optical fibers compliant with ITU-T G.652.D are now among the best standard single-mode fibers on the market. Before introduction of the G.652.D recommendations, optical systems could use one of the three transmission windows with lower attenuation (I: 850 nm, II: 1310 nm, III: 1550 nm). Systems based on optical fibers with low water peak can work in the whole band from 1280 nm to 1650 nm.
