The JBX85081 35-meter LC/ST duplex singlemode fiber patch cable represents a reliable solution for professional networking and telecommunications infrastructure. Designed and tested to ANSI/TIA/EIA standards, this cable delivers consistent performance in demanding environments. **Technical Excellence** Built with a 9/125 singlemode fiber core using G.657.A1 glass composition, this cable achieves exceptional optical performance. The ≤0.35dB insertion loss (0.15dB typical) ensures minimal signal degradation, critical for long-distance transmissions. Return loss specifications exceeding 20dB prevent unwanted signal reflections that could compromise network stability. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm support dual-wavelength applications. **Connector Configuration** The LC/UPC to ST/UPC connector pairing provides the duplex Type A to B crossover configuration standard in most telecommunications equipment. These industry-standard connectors ensure compatibility with existing infrastructure while maintaining polarity integrity essential for proper signal transmission. **Installation and Safety** The yellow OFNR (Optical Fiber Non-conductive Riser) jacket rating permits installation through building plenum spaces and vertical runs where fire safety standards apply. The compact 1.8mm diameter enables easy routing through conduit and cable trays without compromising bend radius integrity. At 35 meters, this length accommodates floor-to-floor connections in multi-story facilities. **Compliance and Reliability** RoHS and ELV directives compliance ensures environmental responsibility and regulatory adherence. Each cable is manufactured to stringent quality standards with insertion loss testing per ANSI specifications. The 90-day limited warranty provides confidence in product reliability. **Custom Availability** Recognizing varied installation requirements, custom lengths are available beyond standard offerings. Ships from multiple US distribution centers—Danville CA, Fort Worth TX, and Beaufort SC—with free standard shipping on orders exceeding $99. **Applications** Ideal for telecommunications closets, data center interconnects, campus network extensions, and anywhere singlemode fiber transmission is required across distances exceeding multimode cable capabilities.
