The JBX88273 ST/ST duplex singlemode fiber patch cable represents a premium solution for professional network installations demanding superior performance and reliability. This 60-meter cable is specifically engineered for single-mode fiber applications where precise signal transmission over extended distances is critical. **Key Technical Features:** Constructed with a 9/125 micron core and G.657.A1 glass fiber, this cable delivers exceptional signal integrity with insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB. The cable maintains attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, making it ideal for both traditional and modern wavelength requirements. Testing complies with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent performance metrics. **Design & Durability:** The duplex configuration with Type A to B crossover polarity enables seamless integration into existing network architectures. ST/UPC connectors provide reliable connections with minimal signal loss. The riser-rated (OFNR) PVC jacket offers flame resistance and environmental protection, while the compact 1.8mm outer diameter ensures easy routing through cable trays and conduits. **Compliance & Certifications:** Fully TAA compliant, this patch cable meets government procurement requirements. RoHS and ELV directive compliance (EU directive 2002/95/EC) ensures environmental responsibility and safety standards adherence. **Applications:** Ideal for data centers, telecommunications facilities, network backbone installations, and long-distance signal transmission. The extended 60-meter length eliminates intermediate splice points, reducing potential failure points and installation complexity. **Warranty & Support:** Backed by a 90-day limited warranty. Available in custom lengths for specialized applications. Ships from multiple U.S. locations with free standard shipping on orders exceeding $99, ensuring rapid deployment for time-sensitive network upgrades.
