The JBX43806 25m SC/APC to E2000/APC Simplex Singlemode Fiber Patch Cable represents professional-grade connectivity for mission-critical fiber optic networks. Engineered with precision-aligned 9/125 singlemode fiber adhering to G.657.A1 standards, this simplex cable delivers single-direction signal transmission with exceptional performance metrics. **Key Performance Features:** This cable achieves insertion loss of ≤0.35dB (0.15dB typical) at both 1310nm and 1550nm wavelengths, ensuring minimal signal degradation across the spectrum. The return loss specification of ≥20dB provides superior signal reflection performance, critical for maintaining signal quality in long-distance telecommunications. Attenuation rates of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm meet stringent industry standards. **Construction & Durability:** The 1.8mm outer diameter cable features OFNR (Optical Fiber Non-conductive Riser) rated jacketing suitable for vertical runs in building risers and general horizontal installations. The yellow jacket provides high-visibility identification in complex cable management environments. SC/APC connectors offer industry-standard singlemode connections, while E2000/APC termination ensures compatibility with specialized telecommunications equipment. **Compliance & Standards:** TAA compliant and RoHS/ELV certified, this cable meets government procurement requirements. Manufactured to ANSI/TIA/EIA-455-171-A-2001 standards with attenuation testing verification. Ships from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders exceeding $99. **Flexibility & Support:** Custom lengths available for specialized applications. Backed by comprehensive 90-day limited warranty. Ideal for data center upgrades, telecommunications networks, and high-speed internet service provider installations requiring reliable single-mode fiber connectivity.
