The JBX88332 55-meter ST/ST duplex singlemode fiber patch cable represents a premium solution for organizations requiring dependable, high-performance fiber connectivity. Manufactured with precision-engineered 9/125 singlemode fiber (G.657.A1 specification), this cable is designed to support long-distance, high-bandwidth telecommunications and data transmission applications. **Technical Excellence** This fiber patch cable delivers exceptional performance characteristics validated through rigorous testing. Insertion loss measurements of ≤0.35dB (0.15dB typical) ensure minimal signal attenuation, while return loss of ≥20dB prevents signal reflection and interference. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm make it suitable for both C-band and L-band telecommunications. All performance standards comply with ANSI/TIA/EIA-455-171-A-2001, ensuring compatibility with industry-standard testing protocols. **Superior Construction** The cable features a durable 1.8mm outside diameter with OFNR (Optical Fiber Nonconductive Riser) rated jacketing, providing both flexibility and safety compliance for in-building installations. The Type A to B crossover polarity configuration is the most common duplex arrangement, ensuring seamless integration with standard telecommunications infrastructure. **Compliance & Reliability** TAA compliant for government purchasing requirements, RoHS and ELV certified for environmental standards, and manufactured across facilities in Taiwan, the United States, and China. The cable includes a 90-day limited warranty and ships with free standard shipping on orders exceeding $99 from multiple distribution centers (Danville CA, Fort Worth TX, Beaufort SC), ensuring rapid delivery. **Flexibility** Custom length options are available, allowing you to specify exact cable runs for your specific installation requirements. This eliminates excess cable waste and optimizes network aesthetics and performance. **Ideal Applications** Perfect for telecommunications networks, data center fiber connections, enterprise network backbones, campus area networks (CANs), and any installation requiring reliable, standards-compliant singlemode fiber transmission over extended distances.
