EFB Elektronik A-DQ(ZN)B2Y 4E 9/125µm G657.A1 PE Outdoor Fiber Optic Cable, 4 Fibers, Single-mode, Black, Loose Tube, Rodent Protection

With an attenuation of just 0.22 dB/km at 1550 nm, this outdoor fiber optic cable delivers exceptional signal integrity over long distances, making it a top choice for demanding backbone and FTTx applications. The EFB Elektronik A-DQ(ZN)B2Y 4E 9/125µ G657.A1 PE cable combines bend-insensitive G.657.A1 single-mode fibers with a rugged loose tube construction, ensuring reliable performance in harsh outdoor environments.

Overview

Engineered for direct burial and duct installation, this cable features four single-mode fibers with a 9/125 µm core/cladding diameter, compliant with ITU-T G.657.A1 standards for enhanced bending resistance. The non-metallic construction includes glass yarns for rodent protection and FRP/glass yarns for strain relief, eliminating grounding and lightning concerns. The black polyethylene (PE) outer sheath provides excellent UV resistance and mechanical protection, with a crush resistance of 1000 N/10 cm. The cable has an approximate diameter of 6.2 mm and operates reliably in temperatures from -30°C to +70°C, with installation possible between -5°C and +50°C.

What stands out

• Bend-insensitive G.657.A1 fibers minimize signal loss in tight bends, ideal for complex routing.
• Non-metallic rodent protection using glass yarns ensures long-term durability without the risk of corrosion.
• UV-resistant PE sheath withstands prolonged sun exposure, making it suitable for outdoor aerial and buried installations.
• Low attenuation (≤0.35 dB/km at 1310 nm, ≤0.22 dB/km at 1550 nm) supports high-speed data transmission over long distances.
