Blown Fibre Unit OS2 Singlemode (9/125µm)
General Info
ADC KRONE's optical fibre units are specifically engineered for blown fibre applications. The fibres are contained in a soft inner acrylate layer which cushions the fibres and an outer harder layer which protects the fibres from damage. Glass microspheres, added to the outer layer during manufacturing, provide a low friction layer that assists in improving blowing distances, which are typically in excess of 1000m. The blown fibre units are identified by a colour coded outer layer
- Product Description: Blown Fibre, OS2 Singlemode, 12 Fibre Cores 2000m
- Product Number: 7032 1 402-14
- Application: Campus & Backbone
Features
- Colour coded outer layer identifies the grade of fibre in the unit
- Blowing distances up to 1000m (750m for 12 core)
- Fibre units are manufactured to British Telecom specifications
- Fibres already installed can be removed and replaced with a higher fibre count, ensuring future capacity of the installation
- Once removed, the fibres can be re-used at another site, helping to keep the cost of installation down
- Fibres can be deployed from an external location to the internal presentation point, removing the need to splice at the building entry point
- Compliant to ITU-T Rec. G.652D, low water peak fibre
