OSP MicroCore

AFL MicroCore® optical cables provide a unique blown solution to crowded underground ducts where traditional cable designs are not an option. MicroCore cables are smaller than traditional loose tube optical cables and can be blown into otherwise full ducts, expanding the capacity of existing infrastructure which translates into less expense and faster deployment.

The Microcore product line is a complete solution with a range of designs suitable for applications ranging from backbone networks to FTTx. Whether the need is for high fiber density or small cable diameters, AFL MicroCore® has the solution. Designs are always based on minimal cable and duct diameters to ensure a cost effective installation solution.

Microcore cables are jetted or blown through a network of microducts using compressed air. Conduit systems can be laid and microducts blown in as needed, giving installers the flexibility of deploying fiber only when needed, thereby reducing the initial investment costs. Microcore can also be used for “overriding” existing networks and conduits, which might otherwise be deemed as “at capacity”. The flexible, lightweight cable design which has a low friction jacket allows it to be blown over existing cables within a duct, thereby expanding the capacity of that duct which would have otherwise been deemed full.

AFL now offers OSP MicroCore® EZ-TONE tonable cables. The tonable feature allows network owners that deploy these high-density fiber cables within their underground cabling system the ability to locate them using standard electromagnetic locator devices.


AFL OSP MicroCore® LM-Series is comprised of outside plant (OSP) loose tube fiber optic cables that are optimized for air-jetting into single or bundled micro-duct pathways.
LM200-Series utilizes 200-micron buffered fibers to produce a smaller diameter cable compare to the LM-Series line of micro-loose tube cables. The LM200-Series is available with 24 up to 432 fiber options. LM200 is also available with tone-wire option
The LMHD-Series OSP MicroCore, with its 600-lb load rating and thick-walled outer sheath, is built to support all OSP micro-cable and traditional loose tube fiber optic cable applications.
The MC-Series of AFL MicroCore® are an advanced Blown Fiber Optic Cable system design for the European market. These cables are optimized for air-jetting into micro-duct pathways.
