This CS‑SN duplex patch cord is engineered for next‑generation 400G‑800G high‑density data‑center infrastructures, our CS/UPC‑SN/UPC hybrid duplex VSFF patch cords deliver space‑saving optical cross‑connect performance for hyperscale facilities, AI‑HPC clusters, colocation sites and enterprise core network environments. Adopting proven Very Small Form Factor (VSFF) CS‑SN duplex interfaces, each connector integrates two precision‑polished 1.25 mm ferrules within miniaturized housings, delivering substantially higher port density compared to traditional duplex LC cabling. This compact footprint reduces rack congestion, optimizes panel port utilization and lowers overall capital expenditure for high‑bandwidth network upgrades.
Featuring tool‑free polarity‑reversal capability, these CS‑SN hybrid assemblies enable quick, error‑free adjustments during field installation, moves, adds and changes. Technicians can reconfigure polarity without special tools, greatly accelerating deployment workflows and simplifying ongoing maintenance within densely populated patch panels and distribution frames. Fully interoperable with SFP‑DD, QSFP‑DD and OSFP high‑speed transceivers, the patch cords support direct front‑panel interconnection for 10G, 40G, 100G, 200G, 400G and 800G transmission systems, perfectly matching the bandwidth requirements of modern cloud and artificial‑intelligence compute deployments.
Constructed with premium G.657.A1 bend‑insensitive single‑mode fiber featuring a 10 mm minimum bend radius, these patch cords minimize signal degradation caused by tight cabinet routing and complex cable management layouts. The cable delivers outstanding optical performance with insertion loss ≤0.2 dB and return loss ≥50 dB, ensuring consistent, stable signal transmission over the product service life. The 1.6 mm OFNP plenum‑rated jacket meets strict North‑American plenum‑space fire‑safety standards, making it suitable for installation inside air‑handling plenums typical within commercial data‑center buildings.
Manufactured in‑house under rigorous quality control and compliant with Telcordia GR‑326, TIA‑568, IEC 61754‑series and RoHS requirements, every cable undergoes 100 % factory optical testing for insertion loss and return loss before shipment. The CS and SN connectors support 500 mating cycles, retaining reliable mechanical and optical performance for long‑term continuous operation. The product portfolio covers OS2 single‑mode plus OM3, OM4 and OM5 multimode fiber options to support mixed‑speed network architectures.
Suited for high‑density rack cross‑connections, equipment interconnections, HPC compute clusters and enterprise backbone upgrades, our CS‑SN hybrid VSFF patch cords merge compact mechanical design, plenum‑grade safety performance and consistent low‑loss optical behaviour, delivering future‑proof optical wiring solutions for evolving high‑speed data‑center networks.
