Fiber optic cable we buy
We buy all types of fiber optic cable, new, unused, leftover or used. Full reels, partial reels, boxed coils, cut lengths and mixed lots are welcome. Send photos of the cable, reel tags and estimated footage, and we will make an offer. Include details about its condition so we can review the lot with a clear picture of what you have.
Fiber optic cable carries signals as light through optical fibers. Its identity depends on the fiber category, number of fibers, protective construction and installation listing. Reel weight alone cannot tell us what you have. Our wire and cable buying categories cover the other surplus electrical wire and cable that may be left on the same job.
Keep different part numbers separate, even when the jackets look alike. Two black reels may contain different fiber categories, counts or armor designs.
Single-mode, multimode and protective constructions
Fiber category and cable construction describe different things. Single-mode or multimode identifies the optical fiber. Tight-buffered, loose-tube and armored describe how those fibers are packaged and protected.
| Category or construction | Identification to look for | Detail that matters to a buyer |
|---|---|---|
| Single-mode | SM or OS2 on the tag or specification | Keep the complete fiber designation, not just the word fiber |
| Multimode OM1 | OM1, with a 62.5 micrometer core | Do not group it with 50 micrometer multimode |
| Multimode OM2, OM3 or OM4 | Exact OM category, with a 50 micrometer core | Equal core size does not make these categories interchangeable |
| Tight-buffered distribution | Distribution or tight-buffered construction in the specification | Record fiber count and indoor or indoor/outdoor designation |
| Loose-tube | Fibers protected inside buffer tubes | Identify waterblocking design and intended installation environment |
| Armored fiber | Metal armor identified in the product specification | Show armor condition and whether an outer jacket covers it |
Corning's armored plenum loose-tube family, for example, uses aluminum interlocking armor and offers both single-mode and multimode options. That describes one family, not every armored fiber reel. Other constructions need their own part-number check.
Keep armored fiber separate from armored electrical cable. Metal protection does not turn an optical cable into a power cable.
Fiber counts, metals and installation ratings
For fiber, size usually means the number of individual optical fibers, often called the strand count. Counts such as 12, 24, 48 and 72 appear in manufacturer catalogs. Send the actual count on your tag, including counts outside those examples. A marking such as 24F identifies 24 fibers, not 24 AWG and not 24 copper conductors.
Pure optical fiber has no copper or aluminum signal conductor and is not described by a feeder voltage rating. Metal armor or strength members are separate construction details. If the product combines optical fibers with electrical conductors, send its complete specification, conductor metal, AWG size and any stated voltage rating for review. Do not assign a voltage rating based on the jacket's appearance.
| Cable type letters | What they identify |
|---|---|
| OFNR | Nonconductive optical fiber cable, riser |
| OFNP | Nonconductive optical fiber cable, plenum |
| OFCR | Conductive optical fiber cable, riser |
| OFCP | Conductive optical fiber cable, plenum |
These are cable classifications, not optical performance categories. OS2 does not establish a plenum listing, and outdoor suitability does not establish one either. Read each designation separately.
Optical fiber does not fit the AWG and kcmil size chart. If your lot also includes 14, 12 or 10 AWG building wire, list those electrical conductors separately from the fiber count.
Read the jacket print and reel tag together
Photograph enough of the jacket to capture one complete repeat of its printing. Typical fields can include the manufacturer, product number, SM or MM designation, fiber count, cable diameter, manufacture date or lot code, and sequential length marks. Some cables also show minimum bend diameter and maximum pulling tension. Do not substitute a familiar cable's handling limits for the limits on this reel.
Indoor cable markings should also identify the applicable fire classification. Capture the UL listing mark or other listing information where present, plus any printed temperature rating. If the temperature range is only in the specification, include that document. There is no single temperature rating for all fiber constructions.
The reel tag can supply details missing from the exposed print line: the full catalog number, fiber category, reel identifier and original shipped length. Match that tag to the cable itself. A loose tag lying beside several reels is not enough to identify each one.
For a partial reel, separate original length from footage remaining. Sequential marks help only when you know which marks bound the remaining continuous length. A large number at the exposed end is not automatically the amount left. Our reel-tag and jacket-print guide explains how to organize those details.
Photos that make a fiber lot identifiable
Send current photos of your actual material, not catalog pictures. We need to see both its identity and its condition.
- Show the entire lot so reel quantities and packaging are clear.
- Take a readable close-up of each different reel tag and complete jacket print.
- Show both reel flanges and the outer cable wraps, especially flattened or kinked areas.
- Photograph the protected cable ends and any visible armor or jacket damage without cutting the cable open.
- Include the footage record or inventory sheet. Attach available factory test records that match the reel identifier.
Keep end protection in place. Do not unwind a reel just to make the photo look fuller or expose more cable. Label unknown footage as an estimate rather than presenting it as measured.
What helps or hurts a fiber cable offer
An identifiable, continuous length is easier to review than several unmarked pieces. Matching reels with the same part number, readable tags and documented footage help us understand the lot and affect the offer. Fiber category, listing, manufacture date and current demand also affect the offer.
Physical damage affects the offer even when the jacket still looks mostly intact. Report a reel that was dropped, crushed or sharply bent. A photo cannot prove that every internal fiber is sound. Existing optical test records can provide useful information, but do not describe an untested reel as tested.
Tell us about outdoor storage, sun exposure, water and missing end protection. These details affect the offer. Keep the cable on its reel within the manufacturer's bend limits. Do not remove armor or cut short samples for identification. We confirm who is selling and keep simple paperwork, such as an invoice, purchase order, job closeout paperwork or company letter, with each purchase.
Send identified reels through the offer form for a written offer. We pick up anywhere in Arizona.
Arizona data-center leftovers and closeout mistakes
Chandler's CyrusOne PHX1-PHX8 campus is an established setting for data-center fit-out and network work. In Goodyear, Southland describes Vantage AZ1 as an ongoing data-center development scheduled for completion in 2028. On an active build, check which reels are reserved for later phases before treating them as surplus.
Route revisions, changed fiber counts and unused installation allowances can leave reels after a data hall or backbone phase is finished. Sellers handling data-center surplus cable should preserve the original optical schedule so each reel can be tied to its specified category and listing. For electrical contractors with leftover cable, separate the fiber inventory from power conductors and control wiring before sending photos.
Do not mix fiber with Cat6, Cat6A or coax cable under a single description such as data wire. Avoid counting individual fibers as separate cable lengths. Keep company purchase records or closeout paperwork available. We record the name of the person releasing the reels and confirm their authority to sell company-owned material as a simple part of the purchase.
