This CS‑SN APC duplex patch cord is engineered for next‑generation 400G‑800G high‑density
data‑center infrastructures, our CS/APC‑SN/APC 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.
Utilizing Very Small Form Factor (VSFF) CS‑SN duplex APC‑polish interfaces, each connector integrates two precision‑polished 1.25 mm ferrules within miniaturized housings, delivering significantly higher port density compared with conventional duplex LC cabling.
This compact footprint reduces rack congestion, improves patch‑panel port utilization and optimizes capital expenditure for high‑bandwidth network upgrades.
Featuring tool‑free polarity‑reversal capability and factory‑set A‑B polarity for duplex link operation, these CS‑SN hybrid assemblies support fast, error‑free reconfiguration during field installation, moves, adds and changes. Technicians can adjust polarity without specialized tools, 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 bandwidth requirements of modern cloud‑computing and artificial‑intelligence infrastructure.
Constructed with premium G.657.A2 ultra‑bend‑insensitive single‑mode fiber offering a tight 7.5 mm minimum bend radius, these patch cords mitigate signal degradation caused by sharp bends and constrained cabinet‑cable‑routing scenarios. APC angled‑end‑face polishing delivers excellent return‑loss performance, while insertion loss is controlled ≤0.3 dB to guarantee consistent, stable signal transmission across the product service life.
The 2.0 mm LSZH low‑smoke‑zero‑halogen flame‑retardant jacket meets strict indoor‑safety requirements and is suitable for cabinet‑based data‑center installations.
Manufactured under rigorous in‑house 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 prior to shipment. CS and SN connectors sustain stable mechanical‑optical performance across 500 mating cycles for reliable long‑term operation.
The product portfolio covers OS2 single‑mode as well as 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 APC‑grade VSFF patch cords merge compact mechanical design, superior bend‑tolerant fiber performance and stable APC‑polish optical behaviour, delivering future‑proof optical wiring solutions for evolving high‑speed data‑center networks.
