Overview

The Monoprice 143105 OM3 Fiber Optic Cable is a 3-meter multimode patch cable engineered for high-bandwidth environments including telecom rooms, server farms, and cloud storage networks. Built with Corning optical fiber — an industry standard for signal quality and durability — this cable uses 50/125 micrometer multimode fiber optimized for laser-based 10 Gigabit Ethernet transmission. The reverse polarity LC/LC connectors swap the A and B fiber assignments, which is useful for correcting polarity mismatches in structured cabling systems without needing additional adapters or crossover cables.

The Uniboot design is a notable practical advantage: by combining both fiber strands into a single streamlined jacket and boot assembly, the cable takes up significantly less space than traditional duplex fiber cables. In high-density environments where dozens or hundreds of patch cables run through cable trays and connect to tightly packed patch panels, this reduction in cable volume improves airflow, simplifies tracing, and makes additions and changes faster. The cable is UL listed, confirming it meets recognized safety standards for use in commercial installations. At 3 meters, it is sized for the most common short-distance connections within a single rack or between adjacent racks in a data center row.

Key Features

Uniboot design allows two fibers to be carried inside a single jacket, improving airflow and cable management in tight spaces. Easily reverse the polarity without any tools.

High quality OM3 multi-mode fiber cable with LC/LC connectors is perfect for high-throughput applications. Supports 10Gb to distances up to 300 meters, and 40Gb and 100Gb up to 100 meters.

Effective Modal Bandwidth (EMB) of 2000 MHz/km at 850nm. OFNR (riser) rated fiber cable is ideal for use in upright shafts that run between floors in commercial class buildings.

The small LC connector is perfect for high density network applications.

Use with LED and VCSEL laser light sources. Backward compatible with LED-based 50/125 multi-mode fiber applications.

Pros & Cons

👍 Pros

  • Corning fiber ensures high optical clarity and reliable signal transmission
  • Uniboot design reduces cable volume by roughly half compared to standard duplex cables, improving airflow in dense racks
  • UL listed certification provides confidence in safety and manufacturing standards
  • 3-meter length is well-suited for common rack-to-rack and patch panel connections
  • Reverse polarity eliminates the need for separate polarity-correcting adapters

👎 Cons

  • 3-meter fixed length offers no flexibility for longer or shorter run requirements
  • OM3 multimode fiber is limited to 10Gb, falling behind OM4 and OM5 options for 40Gb or 100Gb future upgrades
  • Reverse polarity configuration may cause confusion if standard polarity is actually needed in your setup
  • Multimode fiber is not suitable for long-distance runs beyond 300 meters at 10Gb

Frequently Asked Questions

Reverse polarity means the fiber strands are crossed at one end, swapping the transmit and receive channels. The Uniboot design combines both fibers into a single compact boot, reducing cable bulk and simplifying cable management in dense patch panels and server racks.
Yes, this cable uses standard LC connectors that fit any LC-compatible SFP, SFP+, or switch port. The reverse polarity simply swaps the A/B fiber assignments, which is useful when you need to correct polarity without a separate adapter or crossover.
This OM3 cable supports up to 10 Gigabit Ethernet. OM3 multimode fiber is rated for 10GbE at distances up to 300 meters, though this particular cable is 3 meters long, well within that range.
No. This is a 3-meter indoor patch cable designed for short connections within telecom rooms, server racks, and data centers. For outdoor or long-distance runs, you would need a different cable type with appropriate jacketing and single-mode fiber.
