The JBX00125 MTP-12 12-Fiber OM4 Multimode Pigtail represents a critical component for modern high-speed optical networking infrastructure. This 0.5m cable assembly features an MTP-12 Female connector on one end and 12 unterminated individual fibers on the other, making it ideal for flexible fiber termination solutions in data centers, telecommunications hubs, and enterprise network environments. **Key Technical Specifications:** Constructed with OM4 50/125 multimode fiber and G.657.A1 glass fiber technology, this pigtail achieves 4700 MHz·km modal bandwidth @ 850nm, supporting 10GbE transmission up to 400m. Insertion loss remains exceptionally low at ≤0.35dB (0.15dB typical), while return loss maintains ≥20dB for signal integrity. Attenuation specifications are 3.0 dB/km @ 850nm and 1.0 dB/km @ 1300nm, ensuring minimal signal degradation. **Design Features:** The 12-color ribbon design provides instant fiber identification, reducing installation time and minimizing errors during termination. Each 0.9mm unjacketed fiber maintains individual color coding throughout the entire length, enabling quick visual verification during patching operations. The straight-through polarity ensures standard signal transmission without cross-coupling issues. **Compliance & Quality Assurance:** Fully RoHS and ELV compliant under EU Directive 2002/95/EC, and TAA-compliant for government procurement. Each unit includes a 90-day limited warranty and ships from multiple US locations (Danville CA, Fort Worth TX, Beaufort SC) with free standard shipping on orders over $99. Custom lengths are available for specific application requirements. **Applications:** Ideal for MTP-to-LC fan-out configurations, high-density patch panel installations, server-to-switch connections, and emergency network restoration scenarios. The unterminated design offers maximum flexibility for custom termination preferences.
