Fiber optic cable selector
Turn five installation decisions into an explainable model shortlist. See the best match, practical alternatives and the questions our engineers still need to confirm.
60–90 second shortlist
Start with the route, not a model number.
Installation method and environmental exposure eliminate unsafe choices first. Structure and market context then rank the remaining DYS models. Results are free, visible immediately and ready to send with a quote request.
No public catalog price: configured cable is quoted by fiber count, construction, length and order quantity. Free or low-cost evaluation samples are available.

Decision logic
How the selector makes a recommendation
- 01
Remove incompatible constructions
Family, installation, self-support, metal restrictions and required structure act as hard constraints.
- 02
Rank valid models
Exposure, jacket and optional construction preferences order only the products that remain technically plausible.
- 03
Expose uncertainty
Unknown fiber counts, market certification scope or conflicting requirements trigger engineering review instead of a made-up exact answer.

- FTTA cable
- Tower and base-station fiber runs needing compact, weather-resistant subcable structures.

Common fiber cable selection mistakes
- Starting with fiber count. Count matters, but the route and construction decide whether the cable survives the installation.
- Calling every armored cable direct-burial cable. Moisture barriers, jacket construction and crush protection must suit soil exposure.
- Ignoring metal restrictions. Lightning-prone and EMI-sensitive routes may need an all-dielectric strength member and armor system.
- Treating company certificates as universal SKU certificates. Match the exact model, jacket and declared scope to the destination market.
- Buying the lowest first cost without an installation plan. Pulling, splicing, attachment hardware and future capacity often determine total project cost.
For additional background, compare direct burial and conduit installation or review the FTTH drop cable guide.
Frequently asked questions
How do I choose between indoor and outdoor fiber optic cable?
Start with the installation environment. Indoor cable prioritizes fire-rated jackets and flexible premises structures. Outdoor cable adds water, UV and mechanical protection for duct, aerial or buried routes. A transition point may require both cable types or a rated indoor/outdoor design.
Should fiber cable be installed in a duct or direct buried?
Duct installation improves access and future replacement, while direct-buried cable needs construction designed for soil moisture, crush and possible rodent exposure. Do not treat a standard duct cable as direct-burial cable unless its exact construction is approved for that use.
When is an all-dielectric cable needed?
All-dielectric construction is useful near power infrastructure, in lightning-prone areas or anywhere metallic strength members and armor are restricted. The route, pulling load and required mechanical protection still need engineering confirmation.
Which FTTH drop cable works for an aerial connection?
A self-supporting flat drop such as GJYXFCH or a round self-supporting design such as GYTC8H is the starting point. Choose the form factor around span, attachment hardware, bend route and local installation practice.
Does the selector confirm UL, CPR or Anatel certification for a product?
No. The market question flags the regional requirement for quotation. DYS holds company and product-line certifications, but the exact SKU, jacket, construction and certificate scope must be confirmed for the order.
