The JBX43049 40-meter LC/APC to LC/APC simplex fiber patch cable represents a superior solution for singlemode fiber optic networking. Built to exacting industry standards, this cable delivers exceptional performance for telecommunications, data center, and enterprise network applications. **Technical Excellence:** This cable features a 9/125 singlemode core that ensures minimal dispersion and maximum signal integrity over extended distances. The LC/APC (Angled Physical Contact) connectors provide industry-leading return loss performance (≥20dB), critical for high-speed data transmission. With insertion loss ≤0.35dB typical at 0.15dB and verified attenuation rates of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm, it exceeds ANSI/TIA/EIA-455-171-A-2001 standards. **Build Quality & Durability:** The 1.8mm outer diameter with OFNR (Optical Fiber Non-conductive Riser) rating ensures safe installation in plenum and riser spaces. The yellow jacket provides superior visibility for cable management and troubleshooting. G.657.A1 glass fiber specification offers bend-insensitive performance for tight routing scenarios. **Compliance & Certification:** TAA-compliant construction meets federal procurement requirements. RoHS/ELV directive compliance ensures environmental responsibility. Manufactured across multiple locations (Taiwan, US, China) with consistent quality control. **Practical Advantages:** Available in custom lengths beyond the standard 40m, allowing flexibility for unique network designs. Free standard shipping on orders over $99 from strategically located fulfillment centers ensures quick delivery. The 90-day limited warranty provides peace of mind for critical installations. **Applications:** Perfect for connecting network equipment, switches, and fiber distribution panels in enterprise data centers, telecommunications facilities, and campus networks requiring singlemode performance. Choose the JBX43049 for reliable, standards-compliant fiber connectivity that professionals trust.
