The JBX43216 4m LC/APC to FC/APC Simplex Singlemode Fiber Patch Cable represents professional-grade connectivity for mission-critical network infrastructure. This TAA-compliant solution meets rigorous government procurement standards, making it ideal for federal projects, defense applications, and regulated industries requiring compliance documentation. **Technical Excellence** Built with a 9/125 singlemode core and G.657.A1 glass fiber construction, this cable delivers exceptional optical performance. The measured insertion loss of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB ensure minimal signal degradation. Attenuation specifications of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm meet stringent telecommunications standards tested per ANSI/TIA/EIA-455-171-A-2001. **Connector Technology** The LC/APC (Lucent Connector with Angled Physical Contact) to FC/APC (Ferrule Connector with Angled Physical Contact) configuration provides superior back-reflection suppression compared to standard connectors. The angled polish design reduces reflection while the precise tolerances ensure reliable signal transmission in singlemode applications. **Installation & Durability** Featuring a yellow OFNR (Optical Fiber Non-conductive Riser) jacket, this cable meets building code requirements for riser installations while providing excellent flame resistance. The 1.8mm outer diameter accommodates standard cable management systems. Custom lengths are available for specialized deployments. **Applications** Ideally suited for data center interconnects, telecommunications networks, laboratory testing, and government installations requiring TAA compliance. The simplex configuration supports point-to-point fiber signal transmission across distances up to 4 meters. **Shipping & Support** Qualifies for free standard shipping on orders exceeding $99. Ships from multiple distribution centers (Danville CA, Fort Worth TX, Beaufort SC). Backed by a 90-day limited warranty and industry-standard RoHS/ELV compliance (EU Directive 2002/95/EC).
