Descriptions
Engineered for next‑generation 10G‑800G high‑density data‑center infrastructures, our SN/UPC‑SN/UPC duplex VSFF patch cords deliver space‑saving optical cross‑connect performance for hyperscale facilities, AI‑HPC clusters, colocation sites and multi‑floor enterprise campus networks. Utilizing
Very Small Form Factor (VSFF) SN‑SN duplex UPC‑polish interfaces, each connector integrates dual precision‑polished 1.25 mm zirconia ferrules within a miniaturized housing, delivering substantially higher port density compared to conventional duplex LC cabling.
This compact footprint reduces rack congestion, improves patch‑panel port utilization and optimizes capital expenditure for high‑bandwidth single‑mode network upgrades.
Featuring push‑pull boot construction and tool‑free polarity‑reversal capability with factory‑set A‑B polarity for duplex link operation, these SN‑SN 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 ongoing maintenance inside densely populated patch panels and distribution frames. Fully interoperable with SFP‑DD and QSFP‑DD high‑speed transceivers, the patch cords support direct front‑panel interconnection for 10G, 40G, 100G, 200G, 400G and 800G transmission systems for single‑mode data‑center links.
Constructed with premium OS2 G.657.A1 bend‑insensitive single‑mode fiber with a 10 mm minimum bend radius, supplied in Φ250 µm bare‑fiber format, these patch cords mitigate signal degradation caused by tight cabinet routing and constrained cable‑management pathways. It delivers consistent optical performance with insertion loss ≤0.2 dB and return loss ≥50 dB to guarantee stable long‑term signal transmission.
The 1.6 mm OFNR riser‑rated flame‑retardant jacket meets 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 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. SN connectors sustain stable mechanical‑optical performance across 500 mating cycles for reliable commercial‑grade operation. The full‑range 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, multi‑floor riser cabling and enterprise backbone upgrades, our SN‑SN VSFF single‑mode patch cords combine compact VSFF mechanical design, riser‑grade fire‑safety performance and stable UPC‑polish optical behaviour, delivering future‑proof optical wiring solutions for evolving high‑speed
data‑center networks.
