The JBX43138 SC/APC to SC/UPC simplex singlemode fiber patch cable represents a premium solution for mission-critical optical signal transmission. With a substantial 35-meter length, this cable accommodates extended runs between network equipment, switching systems, and fiber distribution hubs without requiring additional splicing or connections. **Technical Performance:** Built with G.657.A1 grade singlemode fiber, this cable delivers exceptional performance across standard telecommunications wavelengths. At 1310 nm, attenuation measures 0.25 dB/km, while 1550 nm performance reaches 0.35 dB/km—well within industry specifications. The ≤0.35dB insertion loss and ≥20dB return loss ensure minimal signal degradation, critical for long-distance transmission and high-speed data applications. **Build Quality & Durability:** The simplex design provides single-fiber transmission, ideal for unidirectional applications or paired with separate return paths. The yellow OFNR (Optical Fiber Nonconductive Riser) rated jacket offers flame resistance suitable for building risers and plenum spaces. At 1.8mm outer diameter, the cable balances protection with space efficiency in crowded equipment racks. **Compliance & Procurement:** TAA compliance ensures this cable meets Buy American requirements for government and institutional purchases. RoHS/ELV directives confirm environmental responsibility. Manufacturing across multiple regions (Taiwan, US, China) with multiple fulfillment centers ensures reliable availability and fast delivery. **Applications:** Perfect for data centers, telecommunications hubs, enterprise networks, and CATV systems. The SC/APC connector combination minimizes back-reflection, making it especially valuable in sensitive optical systems. Available in custom lengths for specific installation requirements. **Support & Warranty:** Backed by a 90-day limited warranty, with free standard shipping on orders over $99. Ships from strategically located U.S. facilities for rapid delivery.
