Overview

This 305-meter Reelex pull box of Monoprice Cat5e is a structured cabling backbone component, not a patch cable. The core specification — 24AWG solid bare copper, 350MHz, UTP — translates to three practical outcomes: compliant Gigabit Ethernet performance across full 100-meter runs, legal in-wall deployment under CMR fire ratings, and third-party performance verification via ETL listing. The 350MHz bandwidth rating matters because Cat5e only requires 100MHz; the additional headroom reduces near-end crosstalk (NEXT) and return loss at the limits of a run, where marginal cable would begin to degrade link quality. ETL listing means an independent lab verified these claims against ANSI/TIA-568 — not just the manufacturer.

This spool is built for network installers, IT administrators wiring a new office, and home builders running structured cabling during construction. The 305-meter quantity corresponds exactly to one standard spool — the unit that fills a single Reelex pull box and matches bulk-pricing tiers at most supply houses. The Reelex center-pull dispensing system is a genuine operational advantage: on a long multi-drop run, it eliminates the ladder-climbing, box-repositioning overhead of conventional spool handling. Monoprice positions this cable as a cost-reduction tool for custom-length runs — you terminate only what you need, eliminating the slack loops and zip-tie management that come with pre-made patch cables at scale.

Pros & Cons

👍 Pros

305-meter length covers an entire floor or small building from a single pull box, minimizing splices
Solid bare copper conductors deliver the lowest possible attenuation — not copper-clad aluminum, which degrades signal at distance
350MHz bandwidth rating provides 3.5x the headroom required for Gigabit Ethernet, extending reliable run distances
CMR riser rating satisfies fire code for in-wall and between-floor cable routing without requiring conduit
ETL listed certification confirms third-party testing against ANSI/TIA-568 performance standards

👎 Cons

Solid conductor construction is not flexible enough for patch cables — cutting short lengths for direct device connections will produce a stiff, fragile cable prone to conductor fatigue
UTP shielding offers no protection from dense EMI environments such as electrical conduit runs, industrial equipment, or elevator shafts
305 meters is a fixed quantity — for smaller projects, you pay for more cable than you need with no mid-spool resale option
Cable jacket color is not specified, which may create identification issues in mixed-run installations that rely on color coding
USB 2.0 is not a factor here, but the 100-meter per segment maximum for Cat5e still applies regardless of cable quality — longer runs require a switch or repeater

Frequently Asked Questions

Does the CMR riser rating mean this cable is safe to run through walls and between floors?

Yes — CMR (Communications Multipurpose Cable, Riser) is specifically rated for vertical runs between floors inside building risers. It meets fire safety standards for in-wall and in-ceiling deployment, making it compliant for structured wiring installs. It is not, however, rated for outdoor or direct-burial use.

What's the actual performance ceiling of this Cat5e cable at 350MHz?

350MHz is the tested bandwidth headroom — well above the 100MHz minimum spec for Cat5e. That overhead means the cable supports Gigabit Ethernet (1000BASE-T) without issue and provides signal integrity margin that extends usable run length toward the 100-meter maximum per segment.

Is solid 24AWG copper appropriate for permanent runs, or should I use stranded instead?

Solid 24AWG is the correct choice for permanent, fixed installations — it delivers lower attenuation over long runs compared to stranded wire. Stranded cable is better suited for short patch cables that flex repeatedly. For pulling through conduit or stapling along studs, solid conductor is the standard.

Can I terminate this cable with standard RJ45 keystone jacks and patch panel connectors?

Yes. 24AWG solid UTP Cat5e is the universal standard for keystone jacks, 110-punchdown patch panels, and field-terminated plugs. Any Cat5e-rated termination tool and hardware will accept this conductor gauge without modification.

What does the Reelex packaging format mean for installation?

Reelex is a figure-eight winding method that allows the cable to pay out from the center of the box tangle-free. Unlike traditional spool packaging, Reelex prevents kinking and twist accumulation during long pulls — a meaningful time-saver when pulling runs across an entire floor.
