Description
Standards
International : IEC 60794; ITU-T Rec. G.652Description
This single armoured fibre optic submarine cable is part of the URC-1 family. The cable is intended for surface use or buried where increased protection is required.
The cable can contain up to 96 fibres (type G.652D) protected in a single, stainless steel tube. For fibre counts greater than 96, the fibres are split between four stranded tubes. A polyethylene sheath is extruded around the single tube/stranded tube package to complete the cable core.
A single layer of armouring wires is stranded around the cable core. This is in turn protected by a polyethylene outer sheath.
Several other options are available on request:
- A copper conductor can be applied on the steel tube for electroding purposes (fault location)
- The outer polyethylene sheath can be replaced by polypropylene yarns flooded in bitumen
- Other fibre types and fibre counts can be supplied

For fibre counts > 96, the fibres are divided between four stranded steel tubes. |
||||||||
|
The fillers between the tubes (Q1, Q2, Q3 and Q4) are used to identify the tubes. |
||||||||
|
The filler between Q4 and Q1 is red and the filler between Q1 and Q2 is blue. |
||||||||
|
The other fillers are natural/grey. |
