The JBX24129 MTP-24 to MTP-24 APC Singlemode OS2 Type B 24-fiber jumper represents professional-grade fiber optic connectivity designed for modern high-performance network environments. This 7-meter cable combines advanced specifications with practical design features that address the needs of data center operators, telecommunications professionals, and enterprise network administrators. **Technical Excellence:** This cable features G.657.A1 singlemode fiber with a 9/125 micrometer core, optimized for both 1310nm and 1550nm wavelengths. The attenuation specification of 0.25 dB/km at 1310nm and 0.35 dB/km at 1550nm ensures minimal signal loss over extended runs. With insertion loss rated at ≤0.35dB (typical 0.15dB) and exceptional return loss of ≥60dB, this jumper delivers the reliability required for mission-critical applications. **Robust Construction:** The cable features plenum-rated OFNP jacketing with a 4.0mm outside diameter, meeting building safety codes for installation in air handling spaces and plenum areas. The yellow color coding facilitates quick identification and organization in complex multi-cable installations. MTP/APC connectors provide superior signal integrity with their 8-degree angled polish design. **Type B Polarity Configuration:** The Type B polarity scheme enables proper signal alignment for 24-fiber MTP configurations, essential for maintaining correct channel mapping in high-density patch panel environments. **Compliance & Standards:** Fully RoHS and TAA compliant, this cable meets EU Directive 2002/95/EC requirements and is manufactured to the highest international standards. Testing conducted per ANSI/TIA/EIA-455-171-A-2001 ensures consistent performance and reliability. **Customization & Convenience:** While this product is available as a standard 7-meter length, custom lengths can be ordered to meet specific installation requirements. With free standard shipping on orders over $99 from fulfillment centers in Danville CA, Fort Worth TX, and Beaufort SC, you can receive this professional component quickly and cost-effectively. **Ideal Applications:** • High-density data center patch panels • Telecommunications infrastructure • Enterprise fiber backbone networks • Broadcast and media facilities • Research and testing laboratories Backed by a 90-day limited warranty, the JBX24129 provides confidence in your network infrastructure investment.
