Products » Cables » Miniflex Optical Fibre Drop-Cable (OFDC)
Miniflex Optical Fibre Drop-Cable (OFDC) is a small sized reinforced cable for use in the external, local access infrastructure.
This cable consists of a combination of fibres (with or without water-blocking tapes) such as a blown fibre bundle, a loose tube multi-fibre unit, a small micro-cable or an assembly of 900 micron buffered fibres, sheathed in the Miniflex Optical Fibre Drop Tube (OFDT). The OFDC has a maximum capacity of up to 16 fibres and dry, swellable, water-blocking cords.
The Miniflex OFDC has an outside diameter of 6mm with 2.5mm inner diameter (see diagram overleaf) and provides a reliable, cost-effective solution for self-supporting aerial, direct buried and FTTH drop installations.
• Suspension from overhead telegraph poles
• Direct burial
• Cable ducts
• Surface-laid troughs
• Track side cable support fencing
Performance criteria
A self supporting UV stabilised polymeric sheath of circular crosssection,
incorporating integral high tensile steel strength members and a bore suitable for containing the required fibre assembly.
The construction is rated for use in crossing under or over high
voltage cables up to 11kV.
The mechanical strength is sufficient to allow span lengths up to 68
metres under the specified environmental conditions.
Cable fibre count / capacity
Can contain from 1 to 16 primary buffered fibres, and dry, swell-able,
water blocking cords.
Optical fibre type
Fibre provided in accordance with customer specified requirement.
Typically contains primary coated single-mode optical fibre in accordance with ITU-T Recommendation G652. Proof strain is 1% minimum.
Mechanical performance
OFDC is a self supporting cable with an ultimate tensile strength, not
less than 1350 N and no more than 1550 N.
Installation criteria
For overhead use the OFDC should be attached using a preformed wire spiral anchor. This anchoring system does not tightly bend or restrict the bore of the OFDC in any manner likely to cause any degradation in optical performance of the fibres, even under maximum working tension. For duct use, normal pulling attachments and methods can be used (Maximum Pull Tension 1000N), the same
applies to blowing.
