The JBX43360 SC/APC to ST/UPC simplex singlemode fiber patch cable represents a premium connectivity solution for professional networking environments. With a 0.5m length and simplex (single-strand) configuration, this cable is engineered for applications requiring one-directional fiber signal transmission between network devices. **Technical Specifications:** This cable utilizes 9/125 singlemode fiber construction, the industry standard for long-distance telecommunications. The G.657.A1 glass fiber specification ensures superior performance with attenuation characteristics of 0.25 dB/km at 1310nm or 0.35 dB/km at 1550nm. Testing conducted per ANSI/TIA/EIA-455-171-A-2001 standards confirms insertion loss of ≤0.35dB (0.15dB typical) and return loss ≥20dB, guaranteeing minimal signal degradation. **Connector Quality:** The SC/APC (Angled Physical Contact) connectors on one end provide superior return loss performance, while ST/UPC (Straight Physical Contact) connectors on the other end ensure compatibility with diverse network equipment. The straight-through polarity configuration simplifies installation in mixed-connector environments. **Build Quality & Compliance:** Constructed with OFNR (Optical Fiber Nonconductive Riser-rated) jacket materials, this cable meets demanding building code requirements for vertical cable runs. The yellow outer jacket aids in visual identification and organization within cable management systems. The 1.8mm diameter allows flexible routing without excessive space requirements. TAA (Trade Agreements Act) compliance ensures suitability for government and institutional installations. **Applications:** Ideal for telecommunications facilities, data center cross-connections, laboratory testing, long-distance signal transmission, and network backbone infrastructure. The simplex configuration makes it particularly valuable for unidirectional signal paths in complex network topologies. **Availability & Support:** Offered with free standard shipping on orders exceeding $99, available from multiple U.S. locations for expedited delivery. Custom lengths are available to meet specific installation requirements. The 90-day limited warranty provides confidence in product reliability.
