The JBX89203 60-meter SC/ST duplex singlemode fiber patch cable represents a professional solution for telecommunications infrastructure requiring reliable, high-performance signal transmission over extended distances. This cable combines precise engineering with stringent quality standards to deliver consistent performance in demanding network environments. **Key Technical Features:** With its 9/125 singlemode fiber core and G.657.A1 glass composition, this cable achieves exceptional attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm. The measured insertion loss of ≤0.35dB (typical 0.15dB) ensures minimal signal degradation over the 60-meter span. Return loss specifications of ≥20dB provide excellent signal integrity, critical for applications requiring high-fidelity data transmission. **Connector Configuration:** The SC/UPC to ST/UPC connector pairing features Type A to B crossover polarity, the most commonly specified configuration for duplex patch cords. This allows simultaneous transmission and reception, making it ideal for full-duplex communication systems. Both SC and ST connectors are industry-standard interfaces compatible with most telecommunications equipment. **Compliance & Durability:** TAA compliance ensures procurement eligibility for government and federal projects. RoHS/ELV certification confirms the cable meets environmental protection directives. The OFNR riser-rated jacketing provides flame resistance suitable for vertical installations in building plenum spaces, while the robust 1.8mm diameter withstands regular installation and handling. **Applications:** Perfect for data center interconnects, campus network backbones, telecommunications infrastructure, and enterprise fiber-to-the-desktop deployments. The 60-meter length accommodates medium-distance runs while maintaining performance specifications. **Quality Assurance:** Tested and certified to ANSI/TIA/EIA-455-171-A-2001 standards with 90-day limited warranty coverage. Available in custom lengths for specialized installations. Ships from multiple US locations with free standard shipping on orders over $99.
