The JBX43450 0.5-meter FC/APC to FC/APC simplex singlemode fiber patch cable represents enterprise-grade connectivity engineered for demanding telecommunications and data center environments. This precision-manufactured cable delivers exceptional optical performance with minimal signal degradation, making it the ideal choice for mission-critical applications requiring reliable, high-speed data transmission. **Technical Excellence** Featuring a 9/125 singlemode core with G.657.A1 glass fiber, this cable achieves industry-leading performance metrics. Insertion loss of ≤0.35dB (with typical performance at 0.15dB) ensures minimal signal attenuation across both 1310nm and 1550nm wavelengths. Return loss specification of ≥20dB provides excellent signal integrity and reduced reflections, critical for maintaining data fidelity in long-distance transmissions. **Construction & Compliance** The cable's 1.8mm outside diameter facilitates easy installation in congested cable trays and conduit runs. The yellow OFNR (Optical Fiber Non-conductive Riser) rated jacket ensures compliance with NEC building codes for vertical installations in multi-story buildings. TAA (Trade Agreements Act) compliance certifies this cable for U.S. government and federal agency purchases. **Applications & Use Cases** Ideally suited for telecommunications infrastructure, data center interconnects, ISP backbone networks, and enterprise campus networks. The FC/APC connector design minimizes reflectance, making it particularly valuable for analog video transmission, RF signal distribution, and sensitive measurement applications. Straight-through polarity ensures direct compatibility with standard FC/APC equipment. **Customization & Support** While the standard 0.5-meter length accommodates most patch applications, custom lengths are available for specialized installations. Ships from strategically located U.S. fulfillment centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. Backed by comprehensive 90-day limited warranty covering manufacturing defects. **Attenuation Performance** Attenuation specifications: 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. All cables are attenuation-tested per ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent quality and reliable performance in your network infrastructure.
