The JBX43145 is a premium 70-meter SC/APC to SC/UPC simplex singlemode fiber patch cable engineered for mission-critical network infrastructure. With its extended 70-meter length, this cable is perfect for connecting remote equipment, spanning large data center floors, or bridging network installations where standard patch cable lengths fall short. **Connector Technology** This cable features SC/APC (Angled Physical Contact) on one end and SC/UPC (Ultra Polished Contact) on the other. The APC end provides superior return loss characteristics (≥20dB), making it ideal for applications requiring maximum signal integrity and minimal back-reflection. The UPC connector ensures compatibility with standard network equipment. **Fiber Specifications** Utilizing a 9/125 singlemode fiber core with G.657.A1 glass fiber, this cable delivers exceptional performance for long-distance transmissions. The simplex configuration features a single fiber strand, suitable for unidirectional signal transmission. Low insertion loss specifications (≤0.35dB typical 0.15dB) ensure minimal signal degradation, critical for maintaining network performance across extended distances. **Performance Standards** Attenuation testing complies with ANSI/TIA/EIA-455-171-A-2001 standards. The cable maintains optimal performance with attenuation rates of 0.25dB/km at 1310nm or 0.35dB/km at 1550nm wavelengths, supporting both legacy and modern optical networking systems. **Professional Construction** The OFNR (Riser Rated) jacket with 1.8mm outer diameter provides durable protection while meeting fire code requirements for in-building installations. The distinctive yellow coloring aids cable identification and management in complex network environments. **Compliance & Quality** TAA (Trade Agreements Act) compliance makes this cable suitable for government contracts and procurement requirements. RoHS and ELV directives ensure environmental responsibility. Backed by a 90-day limited warranty and manufactured to US, Taiwan, and China quality standards. **Flexibility & Availability** Available in custom lengths for specialized installations. Ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring quick delivery with free standard shipping on orders exceeding $99. Ideal for telecommunications professionals, network engineers, and data center technicians requiring reliable, compliant fiber connectivity solutions.
