Q1: In case of the FTTH drop cable, what would be the various cores of fiber available?
A1: Frequent arrangements in which are 1, 2, or 4 cores. Single configurations, for example, 6, 8 core is also an alternative for certain cases.
Q2: What type of fiber is used: single-mode or multi-mode? What standards does it meet?
A2: It is often 50/125 μm multi-mode fiber with specs of ITU-T G.651.1 or ISO/IEC 11801 standard.
Q3: What is the core/cladding diameter of the fiber?
A3: 9/125 μm for single-mode fiber.
Q4: How about other optical performance metrics to include insertion loss and return loss values?
A4: The insertion loss is usually ≤ 0.35 dB/km, and a return loss ≥ 60 dB for high-quality single-mode fiber.
Q5: What sort of cable network is used and how the power is supplied to it?
A5: FTTH drop cable can be flat or round, containing FRP (fiber-reinforced plastic) or even steel wires as cable strengthening agents.
Q6: What material is the outer jacket? Is the suit resistant to UV and flame?
A6: The majority is out of LSZH or UV-resistant PE jackets which are ideal for indoor/outdoor usage and compliant with flame-retardant standard.
Q7: What tensile strengths are given for the cable?
A7: The short-term tensile strength of between 80 and 150 N; while the long-term would be about 40 to 80 N depending on the structure.
Q8: And what is the minimum bending radius?
A8: For static use: ≥10 times the cable diameter; for dynamic use: ≥20 times the diameter.
Q9: What range of temperature working condition is accepted?
A9: Indoors: -20°C to +60°C for indoor cables; Outdoor versions reach as low as -40°C to +70°C.
Q10: Is the type of cable waterproof or rodent-proof?
A10: These outdoor FTTH drop wires are usually water-blocked and sometimes armored with rodent-resistant material too.
Q11: How much is the allowed maximum pulling force for underground installation?
A11: Normally ≤150N; it should be sufficiently light to prevent fiber breakage from excessive tensioning.
Q12: Can the cable used be either aerial and conduit installations?
A12: A flat drop cable can certainly be used either in aerial, conduit, or wall-mounted structures.
Q13: What compliance and standards codes are for the FTTH drop cable?
A13: IEC 60794-2, ITU-T G.657, ISO/IEC 11801, RoHS, Telcordia GR-20 (where applicable).
Q14: Do you have any ISO, CE or similar certification?
A14: Indeed, the majority of the suppliers are equipped with the ISO 9001, CE, RoHS, and other certifications.
Q15: To which kind of test results provided an OTDR and IL/RL?
A15: Yes, factory testing involves OTDR, insertion loss, and return loss measurements, as noted at the placement facilities.
Q16: Are 3rd-party tests accredited?
A16: Located mostly in document pool, can be provided as well per project needs.
Q17: What is the item's outer dimension and the weight of the line?
A17: Sheath: 2×5 mm to 3×6 mm; flat cables: approx. 10–25 kg/km.
Q18: How flexible and lightweight is the cable? Is it sufficient for indoor installation?
A18: It could be, conceived to provide flexibility and routing through walls and ducts that is free of tension.
Q19: How will cable be packaged for delivery?
A19: It is usually wrapped on wooden wheels and plastic spools, and has a standard length of 500m up to 2000m.
Q20: Are there an option of a personalized label or specified length of a drum?
A20: Yes, labeling with case numbers or a logo is available.
Q21: Is there a skin layer that can be used to indicate length and attach identification?
A21: Certainly, cable marked specifications such as the number of meters and model/batch number are both printed on the sheath.
Q22: Is it permissible for custom printing onto the cable's jacket?
A22: Sure, the OEM printing service such as the logo, barcode, and serial number is available.
Q23: Are there accessories like connectors and clamps also included?
A23: Same is true i.e. we can deliver SC/APC connectors, wall mount adapters, sleeves, boxes, etc. if demanded.
Q24: Are the accessories matching the approved quality worldwide?
A24: The accessories you asked for do meet the relevant IEC/TIA/ISO standards.
Q25: May we change the kind of fiber as well as the sheath material and printing?
A25: Yes, we understand special needs and have whole OEM/ODM service available, including G.657A1/A2 compliance, sheath color, jacket material, and custom logos printing.
Q26: Hybrid FTTH cables (fiber + power) are leave to produce?
A26: Yes, it would be possible with the hybrid drop cables that integrate hybrid power wires or coaxial cores.
