RamboCables OM3 LC-LC Multimode Fiber Patch Cables — 5m Duplex, 5-Pack, LSZH, Low Insertion Loss

This is a 5-pack of RamboCables OM3 LC-to-LC multimode duplex fiber patch cables, 5 meters each, built for high-density 10G–100G data links with LSZH jackets for safer installations.

These LC–LC OM3 multimode patch cords are manufactured to support modern data center and enterprise network demands. With 50/125µm core/cladding, 850/1300nm operation, and industry-standard OM3 performance, these duplex cables offer low insertion loss and controlled return loss to preserve signal integrity across short- and mid-range optical links. The LSZH (low-smoke, zero-halogen) jacket and quality components make them suitable for enclosed spaces and high-density racks.

How will these cables improve a 10G/40G/100G setup?

These OM3 LC–LC cords are optimized for short-reach multimode connections used by SR optics and high-density transceivers, delivering consistent bandwidth and lower attenuation than inferior multimode variants. They maintain 2000 MHz·km at 850nm, enabling the distances commonly required in data centers and telecom rooms.

• 10GbE reach up to 300 meters at 850nm for typical SR links.
• 40GbE reach up to 240 meters at 850nm with proper QSFP+ configurations.
• 100GbE reach up to 100 meters at 850nm for parallel multimode links.
• Duplex LC connectors support common SFP+/QSFP+ and SR optics.

What construction and performance specs should I expect?

RamboCables uses 50/125µm fiber with precision polishing and high-quality adhesives to reduce signal loss and reflections. The result is a cable that meets tight optical performance metrics while offering mechanical durability for repeated moves and patching in dense panels.

• Insertion loss (IL): ≤0.3 dB, keeping connections efficient.
• Return loss (RL): ≥30 dB to minimize back reflections.
• 2.0 mm duplex cable diameter with minimum bend radius 7.5 mm.
• Operating temperature range: -20°C to 70°C for broad environmental tolerance.

Are these cables safe and easy to install in cabinets and public spaces?

Yes — the LSZH jacket reduces toxic and corrosive smoke if a fire occurs, making these cables a better choice for enclosed or public areas where safety regulations call for low-smoke materials. The thin 2.0 mm profile and duplex LC footprint save space in high-density racks and patch panels.

• LSZH jacket material minimizes smoke and harmful gases in fires.
• Slim profile helps manage high-density cabling runs neatly.
• Standard LC duplex connectors fit most modern patch panels and transceivers.
• Color coding and tidy packaging simplify bulk deployment.

What makes RamboCables a good bulk purchase option?

The 5-pack format is priced and packaged for convenience when outfitting racks or replacing multiple patch cords at once. Buying in a set cuts per-cable cost and reduces procurement steps compared with single-piece orders, while consistent manufacturing reduces variability across cables.

• Five identical 5m cables for uniform installations and spares.
• Competitive pricing for bulk needs in data centers or server rooms.
• Consistent quality control across the pack reduces troubleshooting.
• Ready-to-deploy packaging speeds installation timelines.

Who is this for? Network engineers, data center technicians, telecom installers, and IT managers who need reliable OM3 multimode LC–LC patch cords for 10G/40G/100G short-reach deployments will find these cables suitable. They are particularly helpful when safety-conscious facilities require LSZH jackets and when space is at a premium in high-density panels. Choose RamboCables for consistent optical performance, straightforward installation, and organized bulk purchasing for operational efficiency.
