The JBX42473 represents the optimal solution for professional fiber optic network installations requiring extended cable lengths and superior signal integrity. This 70-meter FC/APC to FC/APC duplex patch cable combines advanced engineering with compliance certifications essential for government and enterprise deployments. **Superior Performance Specifications:** Built with 9/125 micron single mode fiber and G.657.A1 glass composition, this cable achieves exceptional attenuation ratings of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. The measured insertion loss of ≤0.35dB (with typical performance of just 0.15dB) and return loss ≥20dB exceed industry standards for long-distance applications. Performance is verified through rigorous ANSI/TIA/EIA-455-171-A-2001 standard testing. **Key Features:** - 70-meter length accommodates extended network runs - Type A to B crossover polarity configuration (standard for duplex patch cords) - Vibrant yellow jacket for easy identification and cable management - 1.8mm outer diameter provides optimal balance of flexibility and durability - Riser-rated OFNR jacketing for safe installation in commercial spaces - TAA compliant—meets Buy American requirements for government contracts - RoHS and ELV directive compliance ensures environmental responsibility **Ideal Applications:** Suited for telecommunications infrastructure, data center connectivity, campus network backbones, and any mission-critical application requiring reliable signal transmission over extended distances. The duplex configuration simultaneously transmits and receives signals, making it essential for full-duplex communication systems. **Quality Assurance:** Manufactured with precision in Taiwan, US, or China facilities, this cable includes a 90-day limited warranty. Custom lengths are available for specialized applications. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Compliance & Standards:** Meets EU Directive 2002/95/EC (RoHS), classified as optical accessory under Harmonization Code 8544.70.0000, and certified TAA compliant for government procurement eligibility.
