The JBX43079 40-meter LC/APC to SC/UPC singlemode fiber patch cable represents an essential component for professional network installations, data centers, and telecommunications infrastructure. Engineered with precision-molded connectors and a robust construction, this simplex cable delivers exceptional performance for single-channel fiber optic signal transmission. Technical Excellence: Operating at 1310nm and 1550nm wavelengths with attenuation as low as 0.25dB/km at 1310nm or 0.35dB/km at 1550nm, this cable minimizes signal loss over extended distances. The ≤0.35dB insertion loss (0.15dB typical) and ≥20dB return loss ensure clean, reliable signal integrity throughout the cable length. Connector Configuration: The LC/APC connector provides excellent return loss and lower back reflection compared to standard UPC connectors, while the SC/UPC termination offers industry-standard compatibility and ease of use. This combination accommodates diverse network configurations and legacy system integrations. Compliance & Standards: Full TAA compliance makes this cable eligible for government and GSA contract work. RoHS/ELV directives ensure environmental responsibility, while ANSI/TIA/EIA testing standards validate performance. The G.657.A1 rated fiber accommodates tight bend radii without performance degradation. Physical Design: The slim 1.8mm outside diameter with yellow OFNR (Riser Rated) jacket provides space-efficient routing through building conduits while meeting fire safety codes. The 40-meter length addresses typical backbone and intermediate distance requirements. Applications: Perfect for server interconnects, telecommunications closet patching, network upgrades, and any installation requiring low-loss, high-reliability singlemode connectivity. Available in custom lengths for unique installation requirements. Warranty & Support: Backed by a 90-day limited warranty and manufactured in compliance with international quality standards across production facilities in Taiwan, US, and China.
