Product Overview
Excel corrugated steel tape (CST) armoured loose tube optical fibre cables have been designed specifically for applications
requiring a high degree of mechanical protection. These compact, lightweight cables are extremely rugged, provide rodent
resistance and are quick and easy to install. The cables are constructed around a gel filled (non‐dripping and silicon free) tube
containing up to 24 colour coded 250μm primary coated 50/125μm fibres. This tube is covered with water swellable E‐glass
acting as strength members. This cable construction is completed with a longitudinally applied corrugated steel tape and a
flame retardant, low smoke zero halogen, outer sheath.
Performance Overview
Excel loose tube fibre optic cables are designed and manufactured to ensure that optimum performance is possible from
installed fibre links. Support of protocols such as 10 Gigabit Ethernet over maximum distances – 300 metres is assured, due to
improved bandwidth available as standard from Excel fibre cables.
