Application

Nexans UD loose tube fibre cables have been designedfor applications where a high level of installation, environmentaland optical features are required.

The construction is suitable for use outdoor in ducts and fordirect burial. It is a full dielectric armouring design providingrodent resistance. The dielectric armouring consists of half FRPelements and half fillers. The tube is gel filled and has acapacity of up to 24 fibres. The cable has a HDPE outerjacket.

Applications support :

• FDDI 100 Mbps
• Ethernet 10 base FL
• Fast Ethernet 100 base FX
• Gbit Ethernet 1000 base SX/LX
• 10Gbit Ethernet 10000 base SX(*)
• Fibre Channel 1.0625 Gbps
• ATM 155 Mbps
• ATM 622 Mbps

Performance

Nexans loose tube fibre cables are available with a choice offibres which include laser optimised solutions. These allow Gigabitapplications to run over extended distances saving considerableexpense on active equipment.
