Single-mode patch cord ULTIMODE PC-523 is a section of fiber optic cable with a length of 1 meter, terminated on one end with SC/APC connector, and on the other end with FC/APC connector.

FC connectors provide stable connections thanks to threaded metal sleeves. Accidental, strong pull on the fiber does not cause any problems. This type of connector is popular in television systems involving fiber-optic technology. SC connectors are the most popular connectors in FTTH systems. So, the patchcord is often used for connecting optical converters, transmitters and receivers.

APC connectors, due to stepped end style APC ferrule (8 degrees), ensure higher return loss.

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.
