The JBX43385 fiber patch cable represents a professional-grade solution for network infrastructure requiring reliable, long-distance optical signal transmission. With a 70-meter length, this simplex singlemode cable is engineered to meet the rigorous demands of datacenter connectivity, carrier networks, and enterprise telecommunications systems. **Technical Specifications:** This cable features a 9/125 micrometer core, utilizing G.657.A1 glass fiber that exceeds industry performance standards. The SC/APC to ST/UPC connector configuration enables seamless integration into mixed environments where different connector types are present. Measured attenuation of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm ensures minimal signal loss across both transmission windows used in modern optical networks. **Performance & Quality Assurance:** With insertion loss specifications of ≤0.35dB (0.15dB typical) and return loss of ≥20dB, this cable maintains signal integrity critical for high-speed data transmission. All products are tested in accordance with ANSI/TIA/EIA-455-171-A-2001 standards to guarantee consistent performance. **Compliance & Safety:** TAA compliance makes this cable eligible for federal and government procurement programs. RoHS/ELV directive compliance ensures environmentally responsible manufacturing. The riser-rated (OFNR) yellow PVC jacket provides fire resistance suitable for in-building installation while the bright yellow color aids technician visibility during installation and maintenance. **Practical Advantages:** The 1.8mm outside diameter allows for flexible routing through cable trays and conduit systems. Custom length availability accommodates specific installation requirements. Backed by a 90-day limited warranty, this cable ships from multiple U.S. locations with free standard shipping on orders exceeding $99. **Applications:** Ideal for datacenter interconnects, long-distance network backbone installations, carrier POP connections, and any application requiring reliable singlemode fiber transmission over extended distances. The SC/APC to ST/UPC configuration makes it particularly valuable in heterogeneous network environments.
