The JBX00058 FC/APC OS2 Singlemode Fiber Pigtail represents professional-grade optical connectivity for demanding telecommunications and networking applications. As a simplex (single-strand) solution, this 1-meter pigtail provides reliable, single-direction signal transmission while maintaining the compact form factor essential in modern infrastructure deployments. **Superior Optical Performance:** Manufactured with 9/125 micron singlemode fiber featuring G.657.A1 glass composition, this pigtail delivers exceptional optical characteristics. The insertion loss specification of ≤0.35dB (with typical performance of 0.15dB) ensures minimal signal degradation, while the return loss of ≥20dB guarantees superior signal integrity. Attenuation specifications of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm make this pigtail suitable for both short-reach and long-haul applications across industry-standard wavelengths. **Design and Construction:** The FC/APC connector features angled physical contact geometry, which significantly reduces back-reflection compared to standard FC/PC connectors—critical for applications sensitive to return loss. The 0.9mm yellow tight-buffered jacket provides multiple benefits: easy identification in color-coded installations, protection against microbending, and durability in field conditions. The straight-through polarity configuration supports standard simplex transmission requirements. **Compliance and Quality Assurance:** This optical pigtail meets rigorous international standards and compliance requirements. It is RoHS and ELV compliant per EU directive 2002/95/EC, ensuring environmental responsibility. TAA compliance makes it suitable for government and institutional procurement. Performance testing follows ANSI/TIA/EIA-455-171-A-2001 standards, guaranteeing consistent quality across production batches. **Applications and Use Cases:** Ideal for telecommunications networks, data center interconnects, FTTH (Fiber-to-the-Home) installations, laboratory testing, and equipment integration where single-strand optical connectivity is required. The compact 1-meter length suits equipment interfaces, patch panels, and testing scenarios. **Flexibility and Support:** Custom lengths are available to meet specific installation requirements. The product ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring faster delivery. A 90-day limited warranty provides peace of mind for critical applications. Perfect for network professionals, telecommunications engineers, and data center technicians seeking reliable, standards-compliant optical connectivity solutions.
