Single-mode Patch Cord PC-555D (3m, 2xLC-2xLC, G.652D)



LC connectors feature easy installation and provide possibility of using high-density optical ports.
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 reduced peak water can work in the whole band from 1280 nm to 1650 nm.
