| Fiber Type | Single-mode G.652.D or bend-insensitive G.657.A1/A2 | Confirm the fiber designation, attenuation data, mode-field diameter, and compatibility with the installed optical equipment. | Use the exact fiber type specified by the network design; G.657 fibers should remain compatible with the relevant G.652 single-mode system. | Outdoor antenna routes often include tight bends, limited cable-management space, and repeated installation handling. |
| Fiber Count | Common options include 2, 4, 8, 12, 24, or more fibers | Match the count to current radio units, remote electrical tilt systems, fronthaul links, and planned expansion. | Provide enough working fibers plus documented spare capacity without creating unnecessary diameter or weight. | Correct fiber sizing reduces rework while avoiding an oversized cable that is harder to install and secure. |
| Cable Construction | Outdoor distribution, breakout, figure-eight, or hybrid power-and-fiber construction | Review the cross-section, strength members, buffer design, bend radius, pulling method, and termination arrangement. | Construction must suit the route, installation method, connector system, and local support hardware. | FTTA cables may be exposed to wind, vibration, ultraviolet radiation, moisture, and repeated movement near the antenna. |
| Applicable Cable Standard | IEC 60794 series, including the relevant outdoor optical-fibre cable product and test requirements | Request the exact standard edition, test plan, and test reports that apply to the proposed cable construction. | The standard reference should match the cable type and intended installation environment; generic claims are insufficient. | Standards-based verification provides a consistent basis for mechanical, environmental, and optical performance claims. |
| Optical Performance | Attenuation, return loss, insertion loss, and optical continuity | Check test wavelength, measurement method, maximum attenuation, connector loss, and test-data traceability. | Use project-specific limits; verify every finished assembly with an inspection and test record. | Low and stable optical loss helps preserve link margin and reduces intermittent faults during commissioning. |
| Connector Interface | LC, SC, duplex, multi-fibre, or equipment-specific hardened interfaces | Verify connector gender, keying, polish type, fiber count, pin configuration, adapter type, and cable-entry orientation. | The connector must match the radio, remote unit, distribution box, and patching hardware exactly. | Connector mismatch is a frequent cause of delayed installation, high insertion loss, and avoidable field modifications. |
| Ingress Protection | IP-rated connectorized assemblies selected for the installation zone | Confirm the complete mated assembly rating, not only the rating of an individual plug or receptacle. | Use the project-required IP level; IP ratings apply to defined conditions and require correct mating, sealing, and installation. | Sealed interfaces help protect optical connections from dust, rain, spray, and temporary water exposure. |
| Environmental Temperature | Outdoor-rated operating and storage range stated on the datasheet | Compare the cable and connector temperature ratings with the minimum, maximum, solar-load, and storage conditions at site. | The complete assembly must meet the required range; the lowest-rated component limits the system. | Temperature cycling can affect cable materials, seals, connector alignment, and long-term optical stability. |
| Mechanical Strength | Tensile, crush, impact, torsion, vibration, and repeated-bending performance | Review values in the correct units and conditions, including short-term pulling load, long-term load, and minimum bend radius. | Installation loads must remain below the specified limits, and the cable must be supported without exceeding bend restrictions. | Mechanical overload can cause hidden fiber damage even when the outer jacket appears undamaged. |
| UV and Weather Resistance | Outdoor jacket compound with documented resistance to sunlight and weathering | Check jacket material, UV/weathering test method, color stability, and installation suitability for exposed routes. | Use only a cable explicitly rated for outdoor exposure where the route is not protected from sunlight. | UV degradation may cause cracking, embrittlement, water ingress, and premature service failure. |
| Flame and Fire Requirements | Local building-code requirements; EN 50575 CPR classification where applicable in the European market | Confirm whether the route is indoor, outdoor, or transitions into a building, and identify the required reaction-to-fire class. | Do not apply an indoor fire classification automatically to an outdoor cable; obtain the correct declaration and test evidence. | Fire requirements depend on the installation location and jurisdiction, especially at building-entry and equipment-room sections. |
| Material Compliance | Applicable RoHS, REACH, conflict-minerals, and local chemical regulations | Request current declarations covering the cable, jacket, connectors, metallic parts, and packaging where required. | Documentation should identify the product scope, issue date, responsible entity, and applicable legal framework. | Compliance records support procurement approval, import requirements, environmental audits, and responsible product management. |
| Supplier Quality System | Documented quality-management system, preferably certified to ISO 9001 | Verify certificate scope, validity, issuing body, manufacturing location, and whether the certificate covers the supplied product. | A certificate should be current and independently verifiable; certification alone does not replace product testing. | A controlled quality system improves process consistency, traceability, corrective action, and change management. |
| Factory Acceptance Testing | 100% routine testing plus documented sampling or qualification tests | Ask for optical test results, dimensional inspection, connector end-face inspection, continuity checks, and mechanical test records. | Each reel or assembly should have a unique identification number linked to its test results. | Traceable testing helps detect manufacturing variation before the cable reaches a tower or rooftop site. |
| Change Control | Formal notification and approval process for materials, tooling, plant, and design changes | Check whether the supplier notifies customers before changing fiber, jacket compound, connector components, or production location. | Changes should be evaluated for optical, mechanical, environmental, and interoperability impact. | Uncontrolled substitutions can create compatibility problems even when the product name and part description remain unchanged. |
| Documentation Package | Datasheet, drawings, installation guide, test reports, declarations, and packing list | Ensure documents state revision, product configuration, tolerances, test conditions, and storage and handling instructions. | Documents must be consistent with the delivered cable and its actual connector configuration. | Complete documentation reduces installation errors and simplifies inspection, maintenance, and future replacement. |
| Packaging and Logistics | Protective reel or carton packaging suitable for the cable length and route to site | Check reel dimensions, minimum winding diameter, moisture protection, shock protection, labeling, and allowable storage conditions. | Packaging must prevent crushing, excessive bending, contamination, and loss of cable identification during transport. | Damage frequently occurs during handling and shipping rather than during controlled factory production. |
| Installation and Maintenance | Clear routing, securing, cleaning, inspection, and repair procedures | Verify recommended pulling tension, bend radius, connector cleaning method, inspection equipment, and spare strategy. | The installation team should be able to follow the supplier’s instructions without creating undocumented field practices. | Correct handling protects connector end faces and prevents avoidable attenuation, reflections, and intermittent links. |
