How Much Does a 40 Meter Ethernet Cable Cost?

A 40-meter Ethernet cable is a practical length for connecting rooms on different floors, reaching a backyard office, running to an outdoor security camera, or linking equipment across a medium-sized office or shop. It is long enough to need a quality cable but short enough to stay comfortably within Ethernet’s distance limits.

Prices depend on the cable category, construction, jacket rating, and whether you choose a pre-made or bulk cable. For permanent runs inside walls and ceilings, those details are often handled by a Network Cabling Company Torrance, CA homes and businesses rely on to select, install, and test the right cable.

This guide explains typical prices for a 40-meter Ethernet cable, how category affects performance at this length, what drives cost, and how to choose the best cable for your needs.

How Much Does a 40 Meter Ethernet Cable Cost? The Short Answer

A pre-made 40-meter Cat6 Ethernet cable from a reputable brand typically costs about $15 to $50. Cat5e versions are usually slightly less expensive, while Cat6A, outdoor-rated, and shielded cables cost more.

If you cut 40 meters from a bulk box of solid copper Cat6, the cable itself works out to roughly $20 to $40 at typical bulk prices, plus the cost of connectors or jacks.

These are approximate U.S. prices for budgeting only. Actual prices vary by brand, retailer, jacket rating, and market conditions, including changes in copper prices and import costs.

How Long Is a 40 Meter Ethernet Cable in Feet?

Forty meters equals about 131 feet. U.S. retailers usually list cables in feet, so the closest options are often cables between 125 and 150 feet. Some retailers and international sellers also offer cables listed in exact metric lengths, such as 40 meters. Always confirm the length before buying so the cable reaches without excessive slack.

Typical Prices for a 40 Meter Ethernet Cable

The table below shows approximate price ranges for about 40 meters of cable from reputable brands and suppliers.

Option	Approximate Price Range	Notes
Pre-made Cat5e, about 40 meters	$12 to $40	Suitable for Gigabit connections
Pre-made Cat6, about 40 meters	$15 to $50	Best value for most uses
Pre-made Cat6A, about 40 meters	$25 to $70	Most reliable choice for 10 Gigabit
Outdoor-rated Cat6, about 40 meters	$25 to $60	UV-resistant jacket for exterior runs
40 meters of bulk solid copper Cat6	About $20 to $40	Based on typical bulk per-meter prices, plus connectors
1,000-foot (305-meter) Cat6 box	$150 to $400	Best value for multiple runs

How Each Category Performs at 40 Meters

• Cat5e: Supports Gigabit Ethernet and 2.5 Gbps multi-gigabit speeds under IEEE 802.3bz at this length. It works for many basic connections but is rarely chosen for new installations.
• Cat6: Supports Gigabit Ethernet and 5 Gbps multi-gigabit speeds, and at 40 meters it is within the typical 55-meter distance for 10 Gigabit Ethernet. In dense cable bundles with heavy interference between cables, the 10 Gigabit distance can drop to around 37 meters, so results can vary in crowded installations.
• Cat6A: Supports 10 Gigabit Ethernet across the full 100 meters and handles higher-power PoE better, making it the most reliable choice when 10 Gigabit performance is required.

For most homes and offices using Gigabit connections, Cat6 offers the best balance of price and performance at 40 meters.

Is Cat8 Worth It at 40 Meters?

No. Cat8 is designed for short data center connections of up to 30 meters at 25 or 40 Gbps. A 40-meter Cat8 cable exceeds the length defined by the Cat8 standard, and many consumer cables labeled Cat8 are not independently verified. For a 40-meter run, Cat6 or Cat6A is the better and more affordable choice.

Cable Construction and Performance at 40 Meters

Construction matters more as cable length increases. Solid copper conductors have the lowest signal loss and are used for permanent in-wall runs. Stranded conductors are flexible but lose more signal, and TIA standards adjust for this with loss factors: roughly 20 percent more loss for 24 AWG stranded cable, about 50 percent more for 26 AWG, and nearly twice as much for thin 28 AWG cable.

At 40 meters, a standard 24 AWG or 26 AWG stranded cable is generally fine for most connections. Thin 28 AWG slim cables are better suited to short connections, such as in network racks, than to runs of this length.

Cable shape also plays a role. Round cables generally offer better crosstalk performance than flat cables, which are convenient for running under rugs or doors but may not perform as consistently over longer distances.

What Affects the Price of a 40 Meter Cable

• Category: Cat6A costs more than Cat6, which costs more than Cat5e.
• Conductor material: Pure copper costs more than copper-clad aluminum (CCA), which does not meet TIA category standards.
• Jacket rating: Outdoor, direct-burial, riser-rated (CMR), and plenum-rated (CMP) cables cost more.
• Shielding: Shielded cables cost more than unshielded (UTP) cables.
• Cable design: Slim, flat, or specialty cables may be priced higher or lower depending on the brand.
• Brand and verification: UL or Intertek (ETL) verified cables from established brands usually cost more.
• Where you buy: Online retailers often offer lower prices and more length options than retail stores.

Indoor, Outdoor, and In-Wall Options

• Indoor patch cable: A pre-made cable works well for connections that run along walls, under floors, or through open spaces.
• Outdoor cable: For exposed exterior runs, choose UV-resistant, outdoor-rated cable. For underground runs, use direct-burial cable or run outdoor cable in conduit.
• In-wall cable: For permanent runs inside walls and ceilings, use bulk solid copper cable with the correct fire rating, such as CMR for risers or CMP for plenum spaces, terminated on wall jacks and patch panels.

Pre-made patch cables should not be used as permanent in-wall wiring, since they often lack the required fire ratings and are harder to route with connectors attached.

Tips for Buying a 40 Meter Ethernet Cable

• Measure the full route, including vertical runs, corners, and slack at each end.
• Choose Cat6 for Gigabit connections and Cat6A if you need reliable 10 Gigabit performance.
• Confirm the cable uses pure copper, not copper-clad aluminum.
• Avoid thin 28 AWG slim cables for runs of this length.
• Skip Cat8 cables for 40-meter connections.
• Choose round cable over flat cable for more consistent performance.
• Use outdoor-rated or direct-burial cable for exterior installations.

Planning 40-Meter Runs in Torrance Homes and Businesses

Forty-meter runs are common in many Torrance properties, from multi-level homes and backyard offices to offices along Hawthorne Boulevard, retail spaces near Del Amo Fashion Center, and warehouses near Torrance Municipal Airport. Some connections in larger buildings extend even farther, which is why property owners planning longer routes often ask, How much does a 60 meter Cat6 cable cost? Knowing the exact distance of each run helps you choose the right cable length and category, and it keeps every connection within the 100-meter Ethernet limit. For permanent installations, a local cabling contractor can measure routes, install solid copper cable with the correct fire rating, and certify each link after installation.

Conclusion

A pre-made 40-meter Cat6 Ethernet cable typically costs about $15 to $50, while 40 meters cut from bulk solid copper Cat6 costs roughly $20 to $40 at typical bulk prices. Cat5e is slightly less expensive, and Cat6A, outdoor-rated, and shielded cables cost more. At this length, Cat6 handles Gigabit and multi-gigabit speeds and is usually within its 10 Gigabit range, while Cat6A offers the most reliable 10 Gigabit performance and Cat8 offers no real benefit. If your connection is a little shorter, a smaller cable may save money, which leads to another common question: How much does a 30 meter Ethernet cable cost?
