Fiber optic patchcord, CS‑CS duplex multimode patch cord OM3 Multimode Riser (OFNR), 3.0mm Tight Buffered, Polarity A-A, VSFF Assemblies

Engineered for 10G‑100G high‑speed multimode data‑center infrastructures, our CS‑CS duplex multimode patch cord VSFF patch cords deliver space‑saving optical cross‑connect performance for hyperscale facilities, enterprise campus networks and multi‑floor building cabling deployments. Leveraging Very Small Form Factor (VSFF) CS‑CS duplex interfaces, each connector integrates dual precision‑polished 1.25 mm ferrules within a compact housing, delivering significantly higher port density than conventional duplex LC cabling. This miniaturized footprint reduces rack congestion, optimizes patch‑panel port utilization and lowers total cost of ownership for multimode network upgrades.

Featuring push‑pull boot construction and tool‑free polarity‑reversal capability with 3.8 mm ferrule spacing, these CS‑CS assemblies support fast, error‑free reconfiguration during field installation, moves, adds and changes. Technicians can adjust polarity without specialized hand tools, accelerating deployment workflows and simplifying routine maintenance inside densely populated patch panels and distribution frames. Fully interoperable with SFP‑DD and QSFP‑DD multimode transceivers, these patch cords support direct front‑panel interconnection for 10G, 40G and 100G Ethernet transmission systems for short‑reach data‑center links.

Constructed with premium OM3 50/125 µm multimode fiber and robust 3.0 mm tight‑buffered cable structure, the patch cord offers 7.5 mm minimum bend radius to mitigate signal degradation during cabinet routing. It delivers consistent optical performance with insertion loss ≤0.2 dB to guarantee stable high‑speed multimode signal transmission. The OFNR riser‑rated flame‑retardant jacket complies with North‑American riser‑fire standards, suitable for vertical cable runs between building floors and non‑plenum data‑center pathways.

Manufactured under strict in‑house quality control and compliant with IEC 61754 series, IEC 61753‑1, ISO/IEC 11801 and RoHS requirements, every cable undergoes 100 % factory optical testing for insertion loss before shipment. CS connectors maintain stable mechanical‑optical performance over 500 mating cycles for long‑term reliable commercial‑grade operation. The full‑range product portfolio covers OS2 single‑mode, OM3/OM4/OM5 multimode and bend‑insensitive fiber variants, supporting custom‑built hybrid assemblies for mixed‑legacy network environments.

Suited for high‑density rack cross‑connections, equipment interconnections, multi‑floor riser cabling and enterprise backbone upgrades, our CS‑CS VSFF multimode patch cords combine compact VSFF mechanical design, riser‑grade fire‑safety performance and consistent low‑loss multimode behaviour, delivering future‑proof optical wiring solutions for cost‑optimized high‑speed data‑center networks.
