The JBX43812 55-meter SC/APC to E2000/APC Simplex Singlemode Fiber Patch Cable represents enterprise-grade connectivity for organizations requiring reliable, high-performance fiber optic infrastructure. This cable is engineered to meet stringent telecommunications standards and compliance requirements. **Technical Excellence:** Constructed with G.657.A1 glass fiber and featuring a 9/125 singlemode core, this cable delivers industry-leading performance characteristics. With insertion loss of just ≤0.35dB (0.15dB typical) and return loss ≥20dB, it ensures minimal signal degradation over the full 55-meter span. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm exceed standard expectations for long-distance applications. **Compliance & Standards:** TAA compliance makes this cable ideal for government contracts and regulated industry applications. The cable meets ANSI/TIA/EIA-455-171-A-2001 standards for optical fiber attenuation testing and adheres to RoHS and EU directive 2002/95/EC requirements. Riser-rated (OFNR) jacketing ensures safe installation in building plenum spaces. **Design Features:** The distinctive yellow jacket provides superior circuit identification in complex network installations, reducing troubleshooting time and deployment errors. At just 1.8mm outside diameter, the cable offers flexible routing through cable trays and conduit systems. The straight-through polarity configuration ensures straightforward installation without signal reversal concerns. **Applications:** Ideal for data centers, telecommunications facilities, enterprise networks, and long-distance signal transmission. The simplex design with SC/APC and E2000/APC connectors supports legacy and modern network architectures. **Custom Solutions:** While this 55m configuration serves standard applications, custom lengths are available to match your specific infrastructure requirements. Ships from multiple U.S. locations for rapid delivery, with free standard shipping on orders over $99. **Warranty & Support:** Backed by a 90-day limited warranty, demonstrating manufacturer confidence in durability and performance. Manufactured to international standards across Taiwan, US, and China facilities.
