DROPTIC® LM040BK: building connection in 4 mm!
Published on Monday, April 11, 2022
The LM040BK building connection cable is one of the latest DROPTIC® products. Telenco networks' design office offers a 4 to 12 fibre, multi-purpose cable dedicated to building connections.
A cable adapted to all deployment configurations
The versatility of DROPTIC® LM040BK building connection cable is a real asset for installers as it can be used in different installation environments:

- Overhead;
- On a pole or façade;
- For underground deployments by pulling;
- For vertical distribution inside buildings.
With its LSZH sheath, the DROPTIC® LM040BK can be installed indoor and outdoor. Thanks to its small diameter of 4 mm, its resistance and its versatility, the LM040BK 12 FO is the ideal cable for building connections.
Resistance: the main asset of DROPTIC® LM040BK
The DROPTIC® LM040BK building connection cable has mechanical and thermal performances that makes it highly compatible with all the applications for which the cable is intended.
DROPTIC® LM040BK cable can be used in areas where the temperature can go from -40°C to +70°C.
Installed with Telenco® 5/35 FTTH R or Arobase anchor clamps over spans of 50 metres, it can withstand permanent winds of 115 km/h.
Its FRP and aramid reinforced structure also gives it a crush resistance of up to 200 kg and an impact resistance of up to 5 J, without any attenuation of the optical fibres, thus preventing any mechanical risk during installation, such as pedestrian traffic or stapling to walls.
Adaptable to the connection configuration
The LM040BK is a small size 4mm building connection cable that can hold 4, 6, 8 or 12 G.657A2 fibres. Available in black, it is packaged in 1500m reels. However, it is available on request in white, in short lengths and pre-connectorised or not.
Designed for high performance
The LM040BK building connection cable is designed with two FRPs embedded in the sheath, aramid reinforcements, and sealing elements. A 2 to 12 fibre G.657A2 micromodule is inserted into the cable.
