Outdoor optical cable unitube electro base MD-UT-8F-4015 8 fibers single-mode 5.2 mm

Outdoor unitube optical cable electro base MD-UT-8F-4015 is a slim, single-tube fiber cable with 8 single-mode fibres and a 5.2 mm outer diameter. It is designed for outdoor telecommunications and fiber-to-the-premises installations, providing a compact, weather-resistant solution for long-distance links. The unitube construction houses all fibres inside a single loose tube, offering mechanical protection while keeping the cable profile minimal for aerial, duct or direct burial applications.

Advantages

The cable combines a small 5.2 mm diameter with eight single-mode fibres to deliver high-capacity transmission in a compact form factor. Its unitube design simplifies fibre management and splicing while maintaining mechanical strength and environmental resistance. The construction is optimized for varied outdoor deployments—supporting aerial spans, installation in ducts, and direct burial—reducing handling complexity and saving space in conduits and trays.

Suitable for

• Outdoor telecommunications backbones and access networks
• Fiber-to-the-premises (FTTP) and last-mile connections
• Aerial installation on messenger wires or self-supporting routes
• Installation in ducts and microduct systems
• Direct burial in protective conduits or shallow trenches

Key specifications

• Number of fibres: 8 single-mode fibres
• Construction: unitube (single loose tube) design
• Outer diameter: approximately 5.2 mm
• Operating environment: outdoor/weather-resistant
• Suitable deployment methods: aerial, duct, direct burial

How to use

Choose routing according to the planned deployment type—attach to messenger wires for aerial spans, pull through conduits for duct installation, or lay in a prepared trench for burial. Use appropriate cable handling tools to avoid excessive bending and tensile loads; follow recommended minimum bend radius and tension limits specified by the installation standards. Prepare and terminate fibres in outdoor-rated closures or splice enclosures compatible with unitube cables, ensuring seals and strain reliefs are correctly fitted to maintain environmental protection.

Usage recommendations

To ensure long-term performance, protect the cable from sharp edges and avoid repeated bending at the same point. Use gel-filled or mechanical seals in closures when installing in wet environments and select compatible splice trays and connectors for single-mode fibres. Verify routing for mechanical loads and provide adequate slack for temperature variations and maintenance access.
