The JBX43673 LC/UPC to FC/APC simplex singlemode fiber patch cable represents premium connectivity for demanding network environments. At 12 meters in length, this cable bridges connections across server rooms, networking closets, and distributed antenna systems with exceptional reliability. **Technical Excellence** Built on G.657.A1 singlemode glass fiber with a 9/125 micrometer core, this cable delivers industry-leading performance. Attenuation specifications of 0.25dB/km at 1310nm and 0.35dB/km at 1550nm ensure minimal signal loss over distances. The cable achieves insertion loss of just 0.15dB typical (≤0.35dB maximum), while return loss exceeds 20dB—critical for maintaining signal quality in precision optical networks. **Connector Technology** The LC/UPC (Ultra Physical Contact) connector on one end features an 8-degree angled polish, minimizing back-reflections and ensuring optimal signal transmission. The FC/APC (Angled Physical Contact) termination on the opposite end provides mechanical security and precise alignment. This simplex configuration supports unidirectional signal transmission, ideal for applications requiring dedicated send or receive pathways. **Construction and Compliance** The 1.8mm diameter riser-rated (OFNR) PVC jacket provides fire-resistant protection suitable for in-building installations without conduit. Manufactured to strict quality standards and tested per ANSI/TIA/EIA-455-171-A-2001, each cable ensures consistent performance. TAA compliance makes it eligible for federal government contracts and procurement programs. RoHS/ELV certification confirms environmental responsibility and safe materials. **Applications** Perfect for telecommunications infrastructure, data center migrations, CATV networks, and high-speed internet service provider installations. The yellow jacket aids visual identification in complex cable environments. **Warranty and Support** Backed by a 90-day limited warranty. Custom lengths available for specialized installations. Free standard shipping on qualified orders.
