The JBX88313 2-meter ST/ST duplex singlemode fiber patch cable represents the optimal choice for telecommunications professionals and network administrators requiring reliable, standards-compliant fiber optic connectivity. **Superior Technical Performance:** Constructed with 9/125 singlemode fiber core and G.657.A1 glass fiber, this cable ensures minimal signal degradation. Testing confirms insertion loss of ≤0.35dB (0.15dB typical) and return loss of ≥20dB, meeting or exceeding ANSI/TIA/EIA-455-171-A-2001 standards. Attenuation rates of 0.25 dB/km at 1310 nm and 0.35 dB/km at 1550 nm guarantee performance across telecommunications wavelengths. **Compliance & Durability:** TAA-compliant certification ensures eligibility for government and enterprise procurement. RoHS/ELV compliance demonstrates environmental responsibility. The OFNR riser-rated jacketing permits installation in vertical cable runs without conduit, while the compact 1.8mm outer diameter enables dense routing in equipment racks. **Practical Design Features:** The 2-meter length accommodates cross-cabinet and inter-device connections common in data centers and telecom facilities. ST/UPC connectors feature Type A to B crossover configuration, the industry standard for duplex patch cord applications. The durable plastic accessory construction withstands repeated connections. **Customization & Availability:** While this product is available as a 2-meter standard, custom lengths are available for specialized installations. Ships from multiple U.S. locations (Danville CA, Fort Worth TX, Beaufort SC) ensuring rapid delivery with free standard shipping on qualifying orders. **Applications:** Ideal for telecommunications networks, data center interconnects, enterprise campus networks, and any mission-critical fiber optic installations requiring single-mode performance. The 90-day limited warranty provides peace of mind for critical infrastructure investments.
