The JBX43556 fiber patch cable represents premium connectivity for telecommunications, data centers, and enterprise network infrastructure. This 25-meter simplex cable features a specialized ST/APC (Angled Physical Contact) connector on one end and an FC/UPC (Ultra Physical Contact) connector on the other, providing flexible integration across diverse network architectures. **Technical Excellence:** Constructed with 9/125 singlemode fiber core and G.657.A1 grade glass fiber, this cable delivers superior optical performance. Attenuation specifications are industry-leading at 1310 nm (0.25 dB/km) and 1550 nm (0.35 dB/km). The insertion loss of ≤0.35dB with typical performance of 0.15dB ensures minimal signal degradation over the 25-meter span, while return loss ≥20dB maintains signal integrity for critical applications. **Design & Durability:** The distinctive yellow outer jacket not only provides vibrant visual identification in congested cable trays and racks but also indicates the cable's singlemode classification. The 1.8mm diameter enables efficient routing through conduit and tight spaces. Riser-rated (OFNR) jacketing ensures fire safety compliance for indoor vertical installations, meeting UL standards for building codes. **Compliance & Standards:** Full TAA (Trade Agreements Act) compliance makes this cable eligible for government contracts and procurement. RoHS/ELV certification demonstrates environmental responsibility and compliance with EU directives. Testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards, ensuring verified performance metrics. **Flexibility:** While this 25-meter length suits many standard installations, custom lengths are available to optimize your specific network topology and reduce waste. **Warranty & Support:** Backed by a 90-day limited warranty and available from multiple U.S. warehouse locations with free standard shipping on orders exceeding $99.
