These cables are made by bundling tight buffered simplex fibre optic in an outer jacket. Non-metallic, FRP-strength members in the cable give it good tensile strength and electromagnetic protection. The cables have a small diameter, and a lightweight and thick-walled jacket protection to allow for versatile applications. They are used in cable assemblies and in places of high electro-magnetic interference. Each fibre is mechanically reinforced with two successive sheaths of 400μm and 900μm, enabling direct termination of connectors. They are available in PVC,LSZH or plenum outer sheath and a tight buffer: 900μm, 600μm.
These cables are meant for indoor use. They are specially designed for applications like floor distribution, interconnection and equipment.
Excellent strip force stability, fibre-geometrical dimensions and good transmission performance are some of the characteristics of this cable. Tight-buffered cables are also easier to install because there is no gel to clean up and they do not require a fan out kit for splicing or termination. Connectors can be crimped directly to each fibre.
2/4/6/8/12/16 single mode fibres in full compliance with ITU-T G652D (also available with G657 SM fibre and OM1 / OM2 / OM3 & OM4 MM fibre).
Tight-buffered cables, are optimised for indoor applications. Since they are sturdier than loose-tube cables, they are best suited for moderate-length LAN/WAN connections, long indoor runs and even direct burial. Tight-buffered cables are also recommended for underwater applications.
