The JBX42203 60-meter LC/APC to FC/UPC duplex singlemode fiber patch cable represents professional-grade connectivity engineered for critical network infrastructure applications. This cable combines precision optics with robust construction to deliver reliable fiber signal transmission across long distances. **Key Technical Specifications:** Constructed with 9/125 singlemode fiber core (G.657.A1 glass fiber), this cable supports high-bandwidth data transmission with minimal signal degradation. The duplex configuration allows simultaneous bidirectional communication using Type A to B crossover polarity—the industry standard for duplex patch cords. Insertion loss testing confirms performance of ≤0.35dB at both 1310nm and 1550nm wavelengths, with typical attenuation of just 0.15dB, ensuring signal integrity over the full 60-meter length. **Connector Technology:** The LC/APC connector provides angled-polished surfaces that maximize return loss performance (≥20dB), reducing back-reflection and signal contamination. The FC/UPC connector features universal polished termination for broader compatibility. This combination makes the cable ideal for interconnecting diverse network equipment. **Compliance & Standards:** TAA-compliant manufacturing ensures compatibility with federal procurement regulations. RoHS and ELV directive compliance demonstrates environmental responsibility. The cable has been attenuation-tested per ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing performance consistency. **Physical Design:** The bright yellow 1.8mm diameter jacket enables quick identification in complex cable installations while maintaining a compact profile. OFNR riser-rating permits vertical installation in building walls without conduit, simplifying deployment in multi-story facilities. **Applications:** Ideal for data centers, telecommunications infrastructure, campus networks, and any application requiring reliable singlemode fiber connectivity. The 60-meter length accommodates longer horizontal runs while the duplex configuration supports full-duplex communication protocols. **Shipping & Support:** Eligible for free standard shipping on orders exceeding $99, with rapid fulfillment from Danville, CA; Fort Worth, TX; or Beaufort, SC locations. Backed by a 90-day limited warranty. Custom lengths available upon request for specialized installations.
