The JBX88253 ST/ST singlemode fiber patch cable represents a premium solution for telecommunications professionals, data center operators, and network integrators. This 2-meter cable delivers exceptional performance characteristics suitable for single-mode fiber optic networks requiring precise signal transmission over moderate distances. **Technical Excellence** Built with G.657.A1 glass fiber technology, this 9/125 singlemode cable provides superior performance metrics. The insertion loss specification of ≤0.35dB (with typical performance at 0.15dB) ensures minimal signal degradation, while return loss ≥20dB maintains signal integrity. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm conform to industry standards and support long-distance telecommunications applications. **Compliance and Standards** As a TAA-compliant product meeting RoHS/ELV directives, this cable satisfies government procurement requirements and environmental regulations. The OFNR riser-rated jacketing ensures compliance with building safety codes while providing flame-resistant protection. All performance testing adheres to ANSI/TIA/EIA-455-171-A-2001 standards. **Practical Design Features** The ST/UPC connector configuration with Type A to B crossover polarity represents industry-standard duplex patch cord setup, compatible with existing network infrastructure. The compact 1.8mm outside diameter facilitates installation in cable trays, conduit, and tight equipment enclosures. Blue jacketing enables quick visual identification within network installations. **Versatile Applications** This cable excels in telecommunications facilities, fiber-to-the-premises installations, data center interconnections, and laboratory environments. The 2-meter length provides flexibility for equipment spacing while maintaining optimal signal quality. Custom lengths accommodate specialized architectural requirements. **Value Proposition** With free standard shipping on orders exceeding $99 and a 90-day limited warranty, this TAA-compliant solution delivers enterprise-grade reliability at competitive pricing. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery to end-users nationwide.
