The JBX42593 ST/APC to FC/APC duplex singlemode fiber patch cable represents enterprise-class connectivity for mission-critical fiber optic networks. With a robust 60-meter length, this cable accommodates medium-distance runs typical in data centers, telecommunications facilities, and campus network deployments. Technical Excellence: Constructed with G.657.A1 grade singlemode fiber featuring a 9/125 micron core, this cable provides the precision required for high-bandwidth, long-distance fiber signal transmission. The singlemode design minimizes modal dispersion, enabling superior signal clarity and extended transmission distances compared to multimode alternatives. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal loss across critical telecom wavelengths. Connector Specifications: The ST/APC to FC/APC configuration with Type A to B crossover polarity is the industry standard for duplex patch cord applications. APC (Angled Physical Contact) connectors provide superior return loss characteristics (≥20dB) essential for minimizing back-reflections and maintaining signal integrity in sensitive optical systems. Infrastructure Ready: The yellow OFNR (Optical Fiber Non-Conductive Riser) rated jacket provides optimal performance in vertical cable runs and plenum environments while maintaining fire safety standards. The compact 1.8mm outer diameter facilitates clean installations through existing cable management systems. Compliance & Reliability: Full TAA compliance ensures compatibility with government and enterprise procurement standards. RoHS/ELV directive adherence guarantees environmental responsibility. Manufactured across multiple locations (Taiwan, US, China) with rigorous ANSI/TIA/EIA testing standards. Backed by a 90-day limited warranty. Applications: Ideal for telecommunications infrastructure, data center interconnects, long-haul fiber backbone networks, CWDM/DWDM systems, and any deployment requiring reliable duplex singlemode fiber connectivity. The 60m length bridges equipment across multiple equipment rooms and floor-to-floor installations. Customization Available: Need different lengths? Custom configurations are available to match exact deployment specifications.
