The JBX91064 2.5-meter LC/ST duplex singlemode fiber patch cable represents an ideal solution for professional telecommunications, data center, and enterprise network installations. This precision-engineered component combines cutting-edge fiber optic technology with practical design considerations. **Superior Performance Specifications:** Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable delivers exceptional optical performance. Testing conducted in accordance with ANSI/TIA/EIA-455-171-A-2001 standards confirms insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB. Attenuation ratings of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm ensure reliable long-distance signal transmission with minimal degradation. **Compliance & Quality Assurance:** TAA compliant certification makes this cable eligible for government contracts and regulated procurement environments. RoHS/ELV directive compliance (EU 2002/95/EC) ensures environmental responsibility and safety. The riser-rated OFNR jacketing provides flame-resistant protection suitable for vertical runs in building installations. **Design & Connectivity:** The compact 1.8mm outside diameter permits easy cable management in crowded equipment racks. Type A to B crossover polarity configuration accommodates the most common duplex patch cord applications. LC/UPC to ST/UPC connectors provide secure, low-loss connections with UPC (ultra-physical contact) end faces for optimal performance. **Practical Advantages:** Available in custom lengths for specialized installations, this cable adapts to unique network topology requirements. Free standard shipping on orders over $99 reduces procurement costs. Multiple fulfillment locations (Danville CA, Fort Worth TX, Beaufort SC) ensure rapid delivery. The 90-day limited warranty provides peace-of-mind protection against manufacturing defects. **Applications:** Ideal for campus network connections, data center backbone infrastructure, telecommunications equipment interconnection, and fiber-to-the-premises (FTTP) installations. The 2.5-meter length bridges common distances between network equipment while remaining compact for cable management. Perfect for IT professionals, network engineers, and telecommunications installers requiring reliable, standards-compliant fiber connectivity solutions.
