Quick answer: Choose an FTTH drop cable by the route first: indoor building entry, duct, aerial self-supporting installation, or outdoor access. Then confirm fiber type, fiber count, cable structure, strength members, sheath material, bend radius, tensile load, connector or termination requirements, quantity, and destination. The right cable is the one that fits the route and the installation method without forcing the installer to compensate for a poor mechanical match.
1. Start with the installation route
Indoor and outdoor drop cable can look similar in a catalogue, but they are designed for different risks. Indoor routes usually prioritize compact size, routing flexibility, flame performance, and a clean building-entry transition. Outdoor routes may require UV resistance, moisture protection, greater mechanical protection, or a self-supporting structure.
- Indoor building entry: confirm the bend path, riser or corridor installation, fire and sheath requirements, and the transition into the optical distribution point.
- Duct or conduit: confirm outer diameter, friction, pulling or blowing method, water blocking, and available space in the duct.
- Aerial access: confirm whether the cable needs an integrated messenger or an all-dielectric self-supporting design. Span, sag, wind, ice, and matched hardware matter.
- Outdoor-to-indoor transition: specify where the jacket changes and how the cable will be protected at the entry point.
2. Confirm the optical specification
Fiber count should match the active design plus a practical reserve. Confirm single-mode or multimode fiber, the required fiber standard, attenuation limits, operating window, and the connector or splice system used at both ends. For an FTTH access project, also confirm compatibility with the splitter, terminal, distribution box, closure, and customer-side equipment.
Do not select a cable only because its fiber count looks correct. A jacket, strength system, or bend performance that does not match the route can create installation and maintenance problems later.
3. Match the mechanical design to the route
Ask the supplier to state the cable diameter, weight, minimum bend radius, tensile strength, crush resistance, temperature range, and water-blocking method. For self-supporting aerial cable, request the span and sag-tension design assumptions and the recommended suspension or tension hardware. The values must be confirmed against the actual route rather than copied from a general product page.
4. Specify quantity and delivery conditions
Include the required quantity, drum or reel length, delivery country, project stage, packaging requirements, and target delivery date in the RFQ. A useful request lets the manufacturer recommend a practical construction and return a comparable quotation.
5. Use the right product path
For a focused FTTH discussion, review the FTTH drop cable supply page. If the route is outdoor or aerial, compare it with the outdoor fiber optic cable page before finalizing the cable structure.
FTTH drop cable RFQ checklist
- Installation route and environment
- Fiber type and fiber count
- Self-supporting, duct, indoor, or other structure
- Sheath and strength-member requirements
- Length, quantity, drum, and packaging
- Destination country and project timeline
- Required test reports, standards, and accessories
Send the route, quantity, destination, and basic specification with your request. The manufacturer can then confirm the closest cable construction and identify any missing information before quotation.
