The JBX88417 30-meter ST/ST duplex singlemode fiber patch cable represents a professional solution for organizations requiring reliable, long-distance optical signal transmission. This high-performance cable is engineered with a 9/125 micron singlemode core, delivering superior light transmission characteristics ideal for telecommunications, data centers, and enterprise network infrastructure. Key Performance Specifications: This cable demonstrates exceptional optical performance with insertion loss of ≤0.35dB at maximum (0.15dB typical) and return loss ≥20dB, ensuring minimal signal degradation. The G.657.A1 glass fiber formulation provides consistent performance at both 1310nm and 1550nm wavelengths, with attenuation of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. All testing conforms to ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing industry-leading reliability. Physical Characteristics: Measuring just 1.8mm in outer diameter, this duplex cable provides space-efficient installations while maintaining robust protection. The durable plastic-jacketed design and OFNR riser-rating enable safe deployment in vertical building runs and enclosed spaces without compromise to performance. Compliance and Certification: As a TAA-compliant product meeting EU Directive 2002/95/EC (RoHS), this cable satisfies federal procurement requirements and environmental standards. The Type A to B crossover polarity configuration represents the industry-standard duplex patch cord design. The distinctive pink jacket facilitates easy identification and organization in complex network environments with multiple cable types. Available in custom lengths for specialized requirements, backed by a comprehensive 90-day limited warranty. Ships from multiple US locations with free standard shipping on orders exceeding $99.
