The JBX43712 SC/APC to LC/UPC simplex fiber patch cable is engineered for professionals demanding superior optical performance and reliability. This 1.5-meter cable features precision-terminated connectors that ensure optimal light transmission and minimal signal loss in single-wavelength applications. **Key Specifications:** Utilizing 9/125 singlemode fiber with G.657.A1 glass composition, this cable delivers exceptional performance across standard telecommunications wavelengths. The SC/APC (angled physical contact) connector on one end and LC/UPC (ultra physical contact) connector on the other provide industry-standard compatibility with diverse network equipment. The 1.8mm outer diameter allows for easy routing through cable conduits and patch panels. **Performance Characteristics:** Tested to ANSI/TIA/EIA-455-171-A standards, this cable achieves typical insertion loss of 0.15dB with maximum specification of ≤0.35dB. Return loss exceeds 20dB, ensuring signal integrity and minimal reflections. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm make this cable suitable for long-distance telecommunications applications. **Compliance & Safety:** TAA compliant for government and institutional procurement, this cable meets RoHS and ELV directives (EU 2002/95/EC). The OFNR-rated riser jacket provides fire-safety certification appropriate for installation in building risers and vertical runs. Yellow jacket coloring enables quick visual identification and organization within complex cable installations. **Applications & Benefits:** Ideal for telecommunications networks, data centers, research institutions, and enterprise environments requiring reliable singlemode fiber connections. The simplex design is perfect for unidirectional signal transmission, while custom length availability accommodates unique installation requirements. Backed by a 90-day limited warranty and available from multiple distribution centers (Danville CA, Fort Worth TX, and Beaufort SC), this cable combines professional-grade performance with convenient shipping and support.
