Wentronic LC-LC OM4 duplex multimode optický patch kabel, 50/125µm, LSZH, růžový 95940

For high-speed backbone links where every decibel counts, this OM4 fiber patch cable pairs precision-polished LC connectors with a bend-tolerant 50/125µm core to deliver 100 Gigabit Ethernet over multimode runs. Unlike generic OM3 or single-mode jumpers, its laser-optimized OM4 glass pushes effective modal bandwidth to 4700 MHz·km at 850 nm, making it the practical choice for 40G/100G SR4 optics in modern data centers and campus aggregation layers.

Highlights

• Duplex LC male-to-male connectors, factory terminated and tested for insertion loss ≤ 0.3 dB
• OM4 laser-optimized multimode fiber, backward compatible with existing OM3 infrastructure
• Low-smoke zero-halogen (LSZH) pink jacket for safe use in enclosed or public spaces
• Supports 100GbE, 40GbE, 10GbE and Fibre Channel up to 128GFC depending on transceivers
• Operating range from -20 °C to +70 °C for deployment in non-climate-controlled IDFs and pathways

In daily use

Patch panels, SAN directors and top-of-rack switches connect without polarity guesswork: the duplex clip keeps TX/RX pairs aligned, while the standard LC footprint fits all common SFP, SFP+, QSFP+ and QSFP28 transceivers. The LSZH jacket emits very little smoke and no corrosive halogen gases if exposed to fire, so the cable can be routed through plenum-free riser spaces and public areas without additional conduit. Pink coloring stands out in dense fiber trays, simplifying tracing and change management.

Final note

When upgrading from OM3 to OM4, this cable removes the last bottleneck before 100G optics—without replacing existing patch panels or cassettes.
