| Property | Parameter | Description |
|---|---|---|
| Product Name | G652D Fiber Optic Cable | Single-mode optical fiber cable compliant with ITU-T G.652.D standard |
| Fiber Type | ITU-T G.652.D / IEC 60793-2-50 B1.3 | Standard single-mode fiber with low water peak (LWP), equivalent to OS2 |
| Standard Compliance | ITU-T G.652.D, IEC 60794-1, TIA-568.3-D, GB/T 9771 | Meets international and Chinese national standards for single-mode fiber cables |
| Core/Cladding Diameter | 9/125 μm | Nominal core diameter 9 μm, cladding diameter 125 ± 0.7 μm |
| Attenuation Coefficient | ≤ 0.4 dB/km @ 1310 nm; ≤ 0.3 dB/km @ 1550 nm; ≤ 0.4 dB/km @ 1383 nm | Low water peak attenuation enables full-spectrum transmission (1260–1625 nm) |
| Chromatic Dispersion | ≤ 3.5 ps/(nm·km) @ 1285–1330 nm; ≤ 18 ps/(nm·km) @ 1550 nm | Zero dispersion wavelength: 1300–1324 nm per ITU-T G.652.D |
| Polarization Mode Dispersion (PMD) | ≤ 0.2 ps/√km (link design value) | Suitable for high-speed transmission up to 10 Gbps and beyond |
| Cable Structure | Loose tube / Tight buffer / ADSS / Armored / GYTS / GYTA | Multiple construction types available for indoor, outdoor, aerial, and duct applications |
| Fiber Count | 2 – 288 fibers (custom up to 432F) | Configurable fiber count per cable to meet project requirements |
| Cable Outer Diameter | 6 – 22 mm (varies by fiber count and structure) | Compact design for high-density installations |
| Operating Temperature | -40°C to +70°C (storage: -40°C to +85°C) | Suitable for harsh outdoor and industrial environments |
| Tensile Strength | Short-term: 2700 N; Long-term: 1000 N (GYTS type) | Per IEC 60794-1-2 Method E1; varies by cable construction |
| Crush Resistance | Short-term: 3000 N/100 mm; Long-term: 1000 N/100 mm | Per IEC 60794-1-2 Method E3 |
| Jacket Material | HDPE / LSZH / PVC | HDPE for outdoor; LSZH for indoor/plenum; PVC for general indoor use |
| Certification | ISO 9001, RoHS, CE, UL, TÜV, GB/T 9771 | Third-party certified for quality and safety compliance |
| Application | FTTH, FTTx, LAN, WAN, CATV, Telecom backbone, Data center interconnect | Supports full-spectrum CWDM/DWDM transmission across O, E, S, C, L bands |
| Packaging | Wooden drum / Plastic reel; standard length 2 km, 4 km, 6 km per reel | Custom reel lengths available; drums labeled with OTDR test reports |
| MOQ | 1 km (sample); 10 km (standard order) | OEM/ODM accepted; bulk pricing available for orders ≥ 100 km |
Initial documentation gap resolved promptly — quality of cable itself is fine
Our first order of 40 reels of G652D arrived without the individual per-reel OTDR traces we had specified in the purchase order — only batch-level summaries were included. This was a problem for our client's handover documentation requirements. I raised it with the account team the same day. Within 48 hours, the full per-reel OTDR data was emailed across and a process note was added to our account for future orders. Cable performance itself was fine — attenuation at 1550 nm was 0.19 dB/km on the reels we independently tested. Issue resolved, but worth flagging for other buyers to specify documentation requirements clearly upfront.
