Air Blown Fiber Unit (EPFU)
The EPFU is the product that with small diameter, lightweight, highly flexibility and proper stiffness, and it can be blown into the microduct of 5.0/3.5mm. The Fibers are coated with a soft acrylate resin which provides excellent dimensional and thermal stability to cushion the fibers;FeatureThe EPFU is the product that with small diameter, lightweight, highly flexibility and proper stiffness, and it can be blown into the microduct of 5.0/3.5mm. The Fibers are coated with a soft acrylate resin which provides excellent dimensional and thermal stability to cushion the fibers; in addition, the resin can be easily stripped in connecting the Fibers. The outer sheath is a thermoplastic that is of low friction. The surface of the sheath is designed with special grooves, compared to the surface of the traditional optical fiber cable; it provides not only the high level of mechanical protection, but also the perfect blowing performance.Features and Benefits● 2,4,6,8 and 12 Fibers options.● Stable structure, good mechanical and temperature performance.● Designed with special grooves to advance blowing distance.● Lightweight and proper stiffness, repeat installation.● Designed with no gel, easy stripping and handling.● Better costs advantage compared to traditional product.● Complete accessories, less manpower, lower installationStandardsUnless otherwise specified in this specification, all requirements shall be mainly in accordance with the following standard specifications.● Optical Fibre …...ITU-T G.652、G.657、 IEC 60793-2-50● Optical Cable ……IEC 60794-1-2、IEC 60794-5Technical ParameterFibre Unit StructureBasic PerformanceFiber Count | 2 Fibers | 4 Fibers | 6 Fibers | 8 Fibers | 12 FibersOuter Diameter(mm) | 1.15±0.05 | 1.15±0.05 | 1.35±0.05 | 1.50±0.05 | 1.65±0.05Weight(g/m) | 1.0 | 1.0 | 1.3 | 1.8 | 2.2Min Bend radius(mm) | 50 | 50 | 60 | 80 | 80Fiber type | G652D, G657A1 or G657A2 | G652D, G657A1 or G657A2 | G652D, G657A1 or G657A2 | G652D, G657A1 or G657A2 | G652D, G657A1 or G657A2Attenuation | 0.40dB/km max @1310nm 0.30dB/km max @1550nm | 0.40dB/km max @1310nm 0.30dB/km max @1550nm | 0.40dB/km max @1310nm 0.30dB/km max @1550nm | 0.40dB/km max @1310nm 0.30dB/km max @1550nm | 0.40dB/km max @1310nm 0.30dB/km max @1550nmTemperature | Storage:-30℃ ~ +60℃ Operation:-30℃ ~ +60℃ Installation:-5℃ ~ +50℃ | Storage:-30℃ ~ +60℃ Operation:-30℃ ~ +60℃ Installation:-5℃ ~ +50℃ | Storage:-30℃ ~ +60℃ Operation:-30℃ ~ +60℃ Installation:-5℃ ~ +50℃ | Storage:-30℃ ~ +60℃ Operation:-30℃ ~ +60℃ Installation:-5℃ ~ +50℃ | Storage:-30℃ ~ +60℃ Operation:-30℃ ~ +60℃ Installation:-5℃ ~ +50℃Note: It is recommended that the structure of 2 Fibers unit consist of 2 filled Fibers, for it is proved that 2 Fibers unit with 2 filled Fibers is better than the one with zero or one filled fiber in the blowing performance and the fiber stripping-ability | Note: It is recommended that the structure of 2 Fibers unit consist of 2 filled Fibers, for it is proved that 2 Fibers unit with 2 filled Fibers is better than the one with zero or one filled fiber in the blowing performance and the fiber stripping-ability | Note: It is recommended that the structure of 2 Fibers unit consist of 2 filled Fibers, for it is proved that 2 Fibers unit with 2 filled Fibers is better than the one with zero or one filled fiber in the blowing performance and the fiber stripping-ability | Note: It is recommended that the structure of 2 Fibers unit consist of 2 filled Fibers, for it is proved that 2 Fibers unit with 2 filled Fibers is better than the one with zero or one filled fiber in the blowing performance and the fiber stripping-ability | Note: It is recommended that the structure of 2 Fibers unit consist of 2 filled Fibers, for it is proved that 2 Fibers unit with 2 filled Fibers is better than the one with zero or one filled fiber in the blowing performance and the fiber stripping-ability | Note: It is recommended that the structure of 2 Fibers unit consist of 2 filled Fibers, for it is proved that 2 Fibers unit with 2 filled Fibers is better than the one with zero or one filled fiber in the blowing performance and the fiber stripping-abilityBlowing TestFiber Count | 2 Fibers | 4 Fibers | 6 Fibers | 8 Fibers | 12 FibersStandard duct | 5.0/3.5 mm | 5.0/3.5 mm | 5.0/3.5 mm | 5.0/3.5 mm | 5.0/3.5 mmPressure | 7bar / 10bar | 7bar / 10bar | 7bar / 10bar | 7bar / 10bar | 7bar / 10barTypical blowing distance | 500m / 1000 m | 500m / 1000 m | 500m / 1000 m | 500m / 1000 m | 500m / 800 mTypical blowing time | 10 min / 18 min | 10 min / 18 min | 12 min / 18 min | 13 min / 18 min | 15 min / 20 minMechanical PerformanceTest | Standard | Parameters | Test ResultsTension | IEC 60794-1-2-E1 | Load is 1×W | fibre strain ≤0.4% at MAXAdditional attenuation ≤0.05dBfibre strain ≤0.05% after testBend | IEC 60794-1-2-E11A | Diam 40mm×3turns5 cycles at 20℃ | Additional attenuation ≤0.05dB,after testCrush | IEC 60794-1-2-E3 | 100 N, 60s | Additional attenuation ≤0.05dB,after testAll optical testing proceeded at 1550 nm | All optical testing proceeded at 1550 nm | All optical testing proceeded at 1550 nm | All optical testing proceeded at 1550 nmLengthStandard delivery lengths are 1000m, 2000m, 3000m, 4000m, 6000m with a tolerance of -0.5~+1%.PackagingFree coiling in the pan.
