| Product Name | G.657A2 Bend-Insensitive Single-Mode Optical Fiber | Designed for access networks requiring tight bend radius installations |
| Fiber Category | ITU-T G.657A2 / IEC 60793-2-50 Type B6a2 | Fully compatible with G.652D single-mode fiber; international equivalent to Corning SMF-28 Ultra, OFS BendBright-XS |
| Standard Compliance | ITU-T G.657A2, IEC 60793-2-50, TIA-492AAAD | Meets international telecom and fiber optic standards for bend-insensitive SMF |
| Core Diameter | 8.6–9.5 µm (nominal 9.0 µm) | Compatible with standard G.652D splicing and connectorization |
| Cladding Diameter | 125.0 ± 0.7 µm | Standard 125 µm cladding for universal compatibility |
| Coating Diameter | 245 ± 5 µm (standard); 200 ± 5 µm (reduced) | Dual-layer UV-cured acrylate coating for mechanical protection |
| Attenuation | ≤ 0.20 dB/km @ 1550 nm; ≤ 0.40 dB/km @ 1310 nm | Low attenuation for long-distance signal transmission in FTTH/FTTB deployments |
| Macrobend Loss (Key Parameter) | ≤ 0.1 dB/turn @ 15 mm radius, 1550 nm; ≤ 0.5 dB/turn @ 10 mm radius, 1550 nm | Per ITU-T G.657A2; superior bend performance for conduit and tight-space routing |
| Chromatic Dispersion | ≤ 18 ps/(nm·km) @ 1550 nm; Zero Dispersion Wavelength: 1300–1324 nm | Compliant with G.657A2 dispersion specifications |
| Polarization Mode Dispersion (PMD) | ≤ 0.2 ps/√km (link design value) | Suitable for high-speed transmission up to 10 Gbps and beyond |
| Numerical Aperture | 0.20 ± 0.02 | Standard NA for efficient coupling with G.652D-compatible components |
| Proof Test Level | ≥ 100 kpsi (0.69 GPa) | Ensures mechanical reliability during installation and long-term deployment |
| Operating Temperature | -60°C to +85°C | Suitable for outdoor, indoor, and harsh environment access network applications |
| Application | FTTH, FTTB, FTTC, MDU wiring, indoor/outdoor drop cables, patch cords | Ideal for last-mile access networks, building wiring, and tight-bend installations |
| Certification | RoHS, REACH, UL (optional), CE, ISO 9001 | Compliant with environmental and quality management system requirements |
| Packaging | Wooden reel or plastic bobbin; standard lengths: 2.0 km, 4.0 km, 6.25 km per reel | Custom reel lengths and packaging available upon request |
| MOQ | 500 km per order | Flexible MOQ negotiable for project-based procurement |
Initial coating diameter variance flagged — issue resolved after supplier intervention
First batch of 15,000 meters showed coating diameter readings ranging 241–248 µm on our incoming QC — outside the ±5 µm tolerance specified in IEC 60793-2-50. We raised a formal NCR with the supplier. They responded within 48 hours, arranged third-party re-measurement, and confirmed the variance was within acceptable limits when measured with calibrated equipment. They also provided a replacement reel at no charge as a goodwill gesture. Subsequent 20,000-meter order measured consistently at 245 µm. Optical parameters — attenuation, bend loss — were correct throughout. Supplier accountability improved our confidence.
