The JBX88107 30-meter SC/ST duplex singlemode fiber patch cable represents the gold standard in telecommunications connectivity. Designed for professionals who demand precision and reliability, this cable combines advanced optical specifications with practical features that streamline installation and maintenance. **Superior Optical Performance** Features a 9/125 singlemode core optimized for long-distance, high-bandwidth signal transmission. With attenuation rates of just 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm, this cable minimizes signal degradation over its 30-meter length. Typical insertion loss of 0.15dB and guaranteed maximum of 0.35dB ensure signal integrity for critical applications. Return loss exceeding 20dB provides excellent reflectance control. **Professional-Grade Construction** Manufactured with G.657.A1 glass fiber and housed in a durable 1.8mm OFNR riser-rated jacket for safe installation in building plenums and vertical runs. The distinctive red outer sheath aids rapid cable identification in crowded data center and network closet environments. **Compliance & Standards** TAA (Trade Agreements Act) compliant for government and institutional procurement. Fully RoHS/ELV directive compliant (EU 2002/95/EC). All cables are attenuation-tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards, ensuring consistent, predictable performance. **Practical Benefits** The duplex Type A to B crossover configuration is the industry standard for most patch cord applications. Available in custom lengths for specialized requirements. Ships from three U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99, ensuring quick delivery to your location. **Ideal Applications** Perfect for telecommunications infrastructure, data center interconnects, campus network backbones, and any installation requiring reliable, low-loss singlemode fiber connectivity. The 90-day limited warranty provides peace of mind for mission-critical deployments.
