The JBX90186 SC/ST Duplex Singlemode Fiber Patch Cable represents professional-grade connectivity for mission-critical network infrastructure. This 4-meter cable is specifically engineered to meet the demanding requirements of enterprise data centers, telecommunications facilities, and high-performance computing environments. **Technical Excellence** Featuring a 9/125 singlemode core with G.657.A1 glass fiber technology, this cable delivers exceptional optical performance. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensure minimal signal loss across the full telecom spectrum. The insertion loss specification of ≤0.35dB (typical 0.15dB) and return loss of ≥20dB exceed industry standards, guaranteeing superior signal quality for applications requiring precision optical transmission. **Compliance and Standards** TAA (Trade Agreements Act) compliance ensures this cable meets government procurement requirements for sensitive applications. RoHS/ELV directive compliance confirms environmental safety and sustainability. The cable is tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, providing third-party verification of performance specifications. **Design and Durability** The compact 1.8mm outer diameter accommodates tight cable management scenarios, while riser-rated (OFNR) jacketing provides flame resistance and safety compliance for in-building installations. The distinctive pink jacket facilitates easy cable identification and organization, reducing installation and maintenance time. Type A to B crossover polarity enables standard duplex interconnections without requiring crossover adapters. **Versatile Applications** Ideal for connecting fiber network switches, routers, and optical transceivers in data centers, this patch cable supports both short-distance and longer-haul applications. The 4-meter length accommodates typical equipment spacing while remaining manageable for overhead or conduit routing. Custom lengths are available for specialized installations requiring exact cable runs. **Value and Support** Backed by a 90-day limited warranty and offered with free standard shipping on orders exceeding $99, this professional-grade cable provides excellent value. Manufactured in Taiwan, the United States, and China, the cable is available for immediate shipment from distribution centers in California, Texas, and South Carolina, ensuring rapid delivery nationwide.
