The JBX43021 50-meter LC/APC to LC/UPC simplex singlemode fiber patch cable represents a premium solution for professional fiber optic network installations. Designed with precision engineering and manufactured to exacting standards, this cable delivers the performance and reliability required in demanding telecommunications, data center, and enterprise network environments. Advanced Specifications: This cable features a 9/125 singlemode fiber core with G.657.A1 classification, optimized for both short and long-distance signal transmission. The LC/APC and LC/UPC connector pairing provides excellent signal integrity with insertion loss of just ≤0.35dB (typical 0.15dB) and return loss ≥20dB. These specifications ensure minimal signal degradation and superior performance even in bandwidth-intensive applications. Attenuation Performance: Tested rigorously in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, the cable delivers consistent performance across standard telecommunications wavelengths: 1310 nm at 0.25 dB/km or 1550 nm at 0.35 dB/km. This dual-wavelength performance makes it versatile for various network architectures. Construction and Safety: The cable features riser-rated (OFNR) jacketing, making it suitable for installation in building spaces where plenum-rated cables aren't required. The 1.8mm outside diameter enables space-efficient cable routing through conduits and trays. The bright yellow jacket provides excellent visibility during installation and maintenance, reducing the risk of accidental damage. Compliance and Certification: As a TAA-compliant product manufactured in Taiwan, the United States, or China, this cable meets strict government procurement requirements. Full RoHS/ELV compliance ensures environmental responsibility and regulatory adherence. The cable is available in custom lengths to match specific installation requirements precisely. Applications: Ideal for telecommunications networks, data centers, server room connections, network upgrades, and enterprise installations requiring simplex singlemode connectivity. The 50-meter length accommodates medium-distance backbone and horizontal cabling runs. Value Proposition: With free standard shipping on orders exceeding $99, a 90-day limited warranty, and availability from multiple U.S. distribution centers (Danville, CA; Fort Worth, TX; Beaufort, SC), this cable combines performance, compliance, and convenience. Whether you're upgrading existing infrastructure or building new networks, the JBX43021 delivers professional-grade fiber connectivity backed by industry expertise.
