The JBX88422 55-meter ST/ST duplex singlemode fiber patch cable represents a reliable, cost-effective solution for organizations requiring high-performance optical connectivity. This cable is engineered to meet demanding telecommunications standards and is suitable for extensive network installations where signal integrity and attenuation performance are critical. **Technical Excellence**: Constructed with 9/125 micron singlemode fiber and G.657.A1 glass composition, this cable delivers superior performance characteristics. The insertion loss specification of ≤0.35dB at 1550nm and ≥20dB return loss ensures minimal signal degradation over extended distances. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet industry benchmarks for singlemode transmission. **Standards Compliance**: This cable is fully TAA (Trade Agreements Act) compliant, making it suitable for government and federal procurement. RoHS/ELV certification ensures environmental responsibility, and ANSI/TIA/EIA-455-171-A-2001 testing validates performance consistency. **Practical Design Features**: The OFNR riser-rated jacketing provides fire safety for building installations, while the 1.8mm diameter allows routing through standard conduit and cable trays. Type A to B crossover polarity configuration is pre-installed for immediate compatibility with standard duplex installations. The vibrant pink jacket aids network technicians in cable identification and organization within complex installations. **Flexible Solutions**: Custom lengths are available for specialized applications, providing flexibility beyond the standard 55-meter offering. The cable ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) for expedited delivery. **Value Proposition**: With a 90-day limited warranty, free standard shipping on orders exceeding $99, and proven performance specifications, this patch cable delivers professional-grade reliability at competitive pricing. Ideal for telecommunications rooms, data centers, campus networks, and enterprise installations requiring singlemode connectivity.
