The JBX42134 15-meter SC/APC to SC/UPC duplex single mode fiber patch cable represents professional-grade optical connectivity for demanding networking applications. This carefully engineered cable combines precision manufacturing with industry-standard specifications to deliver reliable, high-performance fiber signal transmission. **Technical Excellence** Featuring a 9/125 singlemode core with G.657.A1 grade glass fiber, this duplex cable achieves exceptional optical performance. The SC/APC connector end provides angled physical contact with superior return loss characteristics (≥20dB), while the SC/UPC end offers standard flat-face contact. This configuration is ideal for asymmetrical applications where signal integrity in one direction is paramount. With insertion loss of ≤0.35dB (typical 0.15dB) and support for both 1310nm and 1550nm wavelengths, the cable accommodates diverse telecommunications standards. **Installation & Compliance** The 1.8mm outside diameter with riser-rated (OFNR) yellow jacket ensures safe, easy installation in building plenums and cable trays. TAA compliance makes it suitable for government and enterprise procurement. RoHS/ELV directives compliance meets environmental standards. Type A to B crossover polarity supports standard duplex communications. **Performance Standards** Attenuation is tested per ANSI/TIA/EIA-455-171-A-2001, ensuring consistency and reliability. The 15-meter length is ideal for medium-distance runs between network equipment, patch panels, and wall outlets. **Applications** Perfect for telecommunications infrastructure, data centers, enterprise networks, telecommunications closets, and fiber-to-the-premise installations. Custom lengths are available for specific deployment requirements. **Warranty & Support** Backed by a 90-day limited warranty.
