Fiber optic cable costs about $0.12 to $1.00 per foot for the common 6 to 12 strand single-mode and multimode cable most commercial projects use. Basic single-mode spools start near $0.12 per foot, while armored, plenum-rated, and high strand-count cable cost more. The cable itself is usually the smaller part of a project, because installation, termination, and testing are priced separately and often cost more than the cable. We are The Network Installers, and we design and install commercial fiber optic cabling for businesses and government agencies, with 19-plus years of work across more than 20,000 locations, so this guide breaks down what the cable costs before labor.
Key Takeaways
- Common commercial fiber cable runs $0.12 to $1.00 per foot. A 1,000-foot single-mode plenum spool works out to about $0.58 per foot, and aqua-jacket OM3 and OM4 multimode runs about $0.83 to $0.99 per foot.
- Single-mode (OS2) is the cheapest fiber per foot, but it pairs with more expensive transceivers than multimode. Multimode OM3 and OM4 suit shorter, high-speed data-center runs.
- Strand count and jacket rating drive material price. A 24-strand cable costs more than a 12-strand run, and plenum-rated (OFNP) cable costs more than riser-rated (OFNR).
- Heavier-jacket cable costs more, about $1.46 to $2.07 per foot, and steel-armored direct-burial cable costs more still.
- Buying full 1,000-foot spools lowers the per-foot cost versus cut-to-length retail. Fiber also lasts far longer than copper, which reduces cost over the life of the network.

What Is the Cost of Fiber Optic Cable?
Fiber optic cable costs $0.12 to $1.00 per foot for the common single-mode and multimode cable used in commercial buildings, based on current bulk pricing from cable distributors. A 1,000-foot spool of 12-strand single-mode plenum cable runs $582.20, about $0.58 per foot, at CableWholesale. Aqua-jacket OM3 and OM4 multimode cable runs about $0.83 to $0.99 per foot in bulk at Cables Plus USA. Basic single-mode distribution spools drop to around $0.12 to $0.22 per foot for riser and plenum ratings at trueCABLE.
Material is only part of the total. Installation, termination, and testing are priced separately and usually cost more than the cable itself.
What Affects Fiber Optic Cable Pricing?
Four things set the price of fiber optic cable: fiber type and strand count, jacket rating, construction, and core material.
- Fiber type and strand count. Single-mode cable costs less per foot than multimode of the same build, and price rises with strand count. Common 6 to 12 strand cable runs $0.12 to $1.00 per foot, and higher counts of 24, 48, or 96 strands cost proportionally more.
- Jacket rating. Plenum-rated cable (OFNP), required in air-handling spaces, costs more than riser-rated (OFNR) cable for vertical runs, which in turn costs more than general-purpose indoor cable.
- Construction. Loose-tube and armored outdoor cable, built for direct burial and harsh environments, costs more than tight-buffered indoor cable. Steel or interlocking armor adds material and weight, which pushes armored cable well above plain indoor cable.
- Core material. Glass fiber delivers the speed and distance commercial networks need. Plastic optical fiber is cheaper but is limited to short, low-speed links, so it is rare in business installations.

Fiber Optic Cable Cost Per Foot by Type
Material cost per foot depends mostly on fiber type, strand count, and jacket. These ranges reflect current bulk pricing from cable distributors.
| Cable type | Cost per foot | Typical use |
|---|---|---|
| Single-mode OS2 (bulk) | $0.35 to $0.92 | Building backbone, runs between buildings |
| Multimode OM3 / OM4 (aqua jacket) | $0.83 to $0.99 | Data center and LAN distribution |
| Single-mode distribution spool (1,000 ft) | $0.12 to $0.22 | Budget bulk pulls |
| Heavier-jacket cable | $1.46 to $2.07 | Rugged, wet, or harsh-environment runs |
Steel-armored and direct-burial cable costs more than the ranges above, depending on the armor type. Buying in bulk lowers the per-foot price: full 1,000-foot spools cost less per foot than cut-to-length orders, and ordering directly from a manufacturer or distributor beats retail for large projects.
What Are the Different Types of Fiber Optic Cable?
Fiber optic cable comes in two main types, single-mode and multimode, separated by core size, distance, and cost.
Single-Mode Fiber (OS1 and OS2)
Single-mode fiber uses a small 8 to 10.5 micron core to carry one light path over long distances, per Wikipedia. It carries signals across very long distances, reaching thousands of kilometers with dense wavelength (DWDM) equipment, which makes it the choice for campus backbones and links between buildings. OS1 cable uses a tight-buffered indoor build, while OS2 uses a loose-tube build for outdoor and long-haul runs.
Multimode Fiber (OM1 to OM5)
Multimode fiber uses a larger 50 or 62.5 micron core that carries several light paths at once, per Wikipedia, which suits shorter, high-speed runs at a lower equipment cost. Reach at 10 Gbps depends on the grade, per the 10 Gigabit Ethernet standard:
- OM1 (62.5 µm): orange jacket, the oldest grade with the shortest reach
- OM2 (50 µm): orange jacket
- OM3 (50 µm): aqua jacket, carries 10 Gigabit Ethernet to 300 meters
- OM4 (50 µm): aqua jacket, carries 10 Gigabit Ethernet farther than OM3
- OM5 (50 µm): lime-green jacket, adds support for 40 and 100 Gbps wavelength multiplexing
OM3 and OM4 are the standard for high-speed data center cabling and enterprise networks. For a full breakdown of grades and builds, see our fiber optic cable types guide.
How Much Does Installation Add?
Installation usually costs more than the cable itself, because fiber work needs trained technicians for pulling, splicing, termination, and testing. Labor is the largest variable in any fiber project, and it changes with building conditions, routing, and distance to existing infrastructure. Per-project and labor pricing lives on our fiber optic installation cost guide, which covers project totals and per-foot install rates in detail.

How to Reduce Fiber Optic Cable Costs
A few choices cut fiber material cost without hurting performance.
- Buy full spools. Ordering 1,000-foot spools or more lowers the per-foot price versus cut-to-length retail. For large jobs, buy directly from a manufacturer or distributor.
- Plan strand count up front. Running a 24-strand cable instead of a 12-strand cable adds little upfront cost and saves a second pull later when you need more capacity.
- Match the fiber to the job. OM3 multimode handles most enterprise runs at a lower cost than OM4. Do not pay for single-mode reach on a short data-center link.
- Reuse existing pathways. Pulling new fiber through existing conduit, trays, or risers avoids new-construction cost. Check that the pathway has spare capacity before you plan the run.
- Get more than one quote. Prices vary by region and contractor, so compare bids for anything beyond a small run.
Is Fiber Optic Cheaper Than Copper in the Long Run?
Fiber optic cable costs more upfront than copper, but it usually wins on total cost of ownership.
- Fewer telecom closets. Copper Ethernet runs are capped at 100 meters, per the twisted-pair Ethernet standard, so large copper networks need intermediate closets and their equipment. Fiber’s longer reach removes many of them.
- Lower maintenance. Glass fiber resists the corrosion, moisture, and temperature swings that degrade copper, so a properly installed fiber network needs less upkeep.
- Longer life. Fiber cabling stays in service for decades, far longer than copper, which is usually replaced sooner. A longer service life spreads the cost over more years.
- Room to grow. Fiber supports faster speeds through equipment upgrades instead of new cable, so the same run carries several generations of gear.
For connection-point pricing on both fiber and copper, see our structured cabling cost per drop guide.
Frequently Asked Questions
How much does fiber optic cable cost per foot?
Fiber optic cable costs about $0.12 to $1.00 per foot for common 6 to 12 strand single-mode and multimode cable. Basic single-mode spools start near $0.12 per foot, while heavier-jacket cable runs more, about $1.46 to $2.07 per foot, and steel-armored direct-burial cable costs more still. Installation is priced separately from the cable.
Can you buy your own fiber optic cable?
Yes. Fiber optic cable is sold by the foot and in bulk spools through cable distributors, and businesses often supply their own cable for a project. Termination and testing still need proper tools and trained technicians, so most commercial buyers pair self-supplied cable with a professional install.
Is fiber optic cable worth it?
For most commercial networks, yes. Fiber costs more upfront than copper but delivers higher speed, longer reach, and a longer service life, which lowers cost over time. It is the standard for building backbones, data centers, and links between buildings.
How far can you run a fiber optic cable?
Single-mode fiber carries signals over very long distances, reaching thousands of kilometers with dense-wavelength (DWDM) equipment. Multimode fiber reaches about 300 meters on OM3 at 10 Gbps, and farther on OM4. Either type covers the distances in most commercial buildings and campuses.
How long does fiber optic cabling last?
Fiber optic cabling stays in service for decades under normal conditions. The glass core does not degrade the way copper does, though proper installation and protection from physical damage affect its life. That long service life is part of why fiber lowers cost over time.
Conclusion
Fiber optic cable costs about $0.12 to $1.00 per foot for the common single-mode and multimode cable commercial projects use, with armored and heavy-jacket cable costing more. The cable is usually the smaller part of the budget, because installation, termination, and testing carry most of the cost. Even so, fiber’s longer reach, lower maintenance, and decades-long service life often make it the cheaper choice over time.
