The JBX43532 55-meter ST/APC to ST/APC simplex fiber patch cable represents professional-grade connectivity for demanding telecommunications and data center environments. This single-strand simplex cable is specifically designed for unidirectional signal transmission, making it ideal for applications requiring dedicated send or receive paths. **Technical Specifications:** This cable features a precision 9/125 micron singlemode fiber core with G.657.A1 glass fiber composition, ensuring minimal signal degradation over extended distances. The cable achieves exceptional optical performance with insertion loss rated at ≤0.35dB (0.15dB typical) and return loss exceeding 20dB, meeting or exceeding industry standards for long-haul fiber transmission. **Construction & Durability:** The 1.8mm outside diameter cable is jacketed with OFNR (Optical Fiber Non-Conductive Riser) rated material, providing flame resistance and compliance with building safety codes. The yellow identification color aids in network management and cable tracking during installation and maintenance. RoHS and ELV compliant construction ensures environmental responsibility. **Standards & Compliance:** Attenuation testing conforms to ANSI/TIA/EIA-455-171-A standards, with documented performance at both 1310nm and 1550nm wavelengths. TAA compliance makes this cable suitable for government and federally-funded projects. The 90-day limited warranty provides confidence in product reliability. **Applications:** Ideal for telecommunications networks, DWDM systems, metro area networks, and enterprise fiber infrastructure requiring single-direction signal paths. The 55-meter length accommodates moderate-distance runs in campus networks and building-to-building connectivity. **Ordering Flexibility:** Custom lengths are available for projects requiring non-standard cable runs. Ships from multiple US distribution centers (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on qualifying orders. TAA compliance available for government procurement requirements.
