| Property | Parameter | Description |
|---|---|---|
| Optical Fiber Product Name | Tight Buffer Indoor Fiber | Single-mode / multimode tight-buffered optical fiber designed for indoor installation environments |
| Fiber Grade & ITU-T Classification | G.652.D (SM) / OM3 / OM4 (MM) | Compliant with ITU-T G.652.D for single-mode; IEC 60793-2-10 for multimode variants |
| Core & Cladding Diameter Range | Core: 8.2 µm (SM) / 50 µm (MM); Cladding: 125 ± 0.7 µm | Tight dimensional tolerance ensures consistent splice and connector performance |
| Attenuation Coefficient at 1310 nm | ≤ 0.35 dB/km (SM) | Measured per IEC 60793-1-40; low attenuation supports long indoor link distances |
| Attenuation Coefficient at 1550 nm | ≤ 0.20 dB/km (SM) | Optimized for C-band transmission in high-density indoor backbone applications |
| Macrobending Loss Performance | ≤ 0.10 dB at R = 15 mm (100 turns, 1550 nm) | Enhanced bend-insensitive design suitable for tight routing in conduits and trays |
| Chromatic Dispersion Coefficient | ≤ 18 ps/(nm·km) at 1550 nm | Meets ITU-T G.652.D dispersion specification for standard single-mode fiber |
| Batch Qualification Rate | ≥ 99.5% | Each production batch undergoes 100% OTDR and attenuation screening before shipment |
| Manufacturing Environment Standards | ISO 9001:2015 certified cleanroom production | Controlled dust-free environment ensures consistent coating adhesion and buffer integrity |
| Core Raw Material Source | High-purity synthetic silica preform (SiO₂ ≥ 99.99%) | Preform sourced from qualified tier-1 suppliers; traceable material certificates provided |
| Packaging Specification | Spool: 1 km / 2 km / 5 km per reel; reel diameter 280–400 mm | Wooden or plastic reels with moisture-proof wrapping; custom lengths available on request |
| Storage Conditions | Temperature: -20 °C to +60 °C; Humidity: 10%–85% RH (non-condensing) | Store away from direct sunlight and corrosive chemicals; keep reel upright |
| Valid Shelf Life | ≥ 20 years under recommended storage conditions | UV-stabilized tight buffer coating prevents degradation during long-term storage |
| Application Scenarios | Indoor backbone, riser, horizontal distribution, FTTH drop, data center patch | Suitable for direct termination without additional furcation tubing due to tight buffer structure |
| Compliance & Certification | ITU-T G.652.D, IEC 60793-2-50, RoHS 2011/65/EU, REACH, UL Listed (OFNR/OFNP) | Flame-retardant jacket meets UL 1666 riser and UL 910 plenum ratings as applicable |
| Minimum Order Quantity (MOQ) | 5 km (single-mode); 2 km (multimode) | Mixed fiber type orders accepted; sample reels of 500 m available for qualification testing |
| Monthly Supply Capacity | 500,000 km / month | Supported by automated draw tower lines with real-time process monitoring and QC traceability |
Initial shipment had a jacket colour mismatch — resolved satisfactorily
Ordered 3,000 m of OM4 tight buffer LSZH cable specifying aqua jackets per ANSI/TIA-568 colour coding for our client's structured cabling standard. First shipment arrived with grey jackets due to a misread order form. This caused a one-week installation delay. To their credit, the supplier acknowledged the error immediately, air-freighted the correct aqua-jacketed OM4 cable within 5 days at no additional cost, and provided a written corrective action report. Optical specs on both batches were fully compliant. Communication after the issue was professional. Cautiously willing to reorder with clearer order confirmation steps.
