Optical fiber cable electro base MD-UT-12F-6.0-3991 — 12 fibers, 5.5 mm outer diameter, outdoor

Outdoor optical fiber cable electro base MD-UT-12F-6.0-3991 is a compact 12-fiber cable with a nominal outer diameter of 5.5 mm, designed for outdoor installations and fiber optic links. The cable supports multiple single-mode or multimode fibers depending on the fiber type used, and is intended for backbone segments, campus networks, aerial or duct runs and last-mile outdoor deployments. Its small cross-section and straightforward design make it suitable where space is limited and multiple fiber channels are required in an outdoor environment.

Advantages

The cable combines a narrow 5.5 mm outer profile with 12 individual fibers, offering efficient use of installation space without sacrificing fiber count. Its outdoor-oriented construction provides resistance to common external factors encountered in aerial, duct or direct-route deployments. The design simplifies routing along poles, through conduits and across campus links while maintaining stable optical performance when properly installed and terminated.

Suitable for

• Outdoor backbone and distribution runs
• Campus and enterprise network interlinks
• Last-mile outdoor fiber deployment
• Aerial and duct installations
• Fiber expansion in existing conduit systems where space is limited

Key specifications

• Number of fibers: 12
• Outer diameter: approximately 5.5 mm
• Fiber types supported: single-mode or multimode depending on fiber selection
• Cable structure: tight-buffered/flexible microcable style for outdoor use
• Installation environments: aerial, duct, direct-route outdoor runs
• Typical temperature range for outdoor deployment: industry-standard operational ranges (verify exact values with manufacturer documentation)

How to use

Plan the route and mounting method appropriate for outdoor fiber: aerial span, duct path or direct-burial conduit where applicable. Use compatible fiber connectors and terminations for the selected fiber type, and perform proper fiber preparation including stripping, cleaning and connectorization or splicing according to standard fiber-optic practices. Secure the cable with suitable clamps, ties or slack-management devices to avoid mechanical stress, and ensure proper bending radius is maintained during installation. After installation, test each fiber with an optical power meter and light source or an OTDR to confirm attenuation and continuity meet expected values.

Usage recommendations

Store and handle the cable to avoid sharp bends and excessive tensile loads. Verify the chosen fiber type (single-mode or multimode) matches equipment transceivers before final termination. For long outdoor runs or critical links, perform end-to-end testing and document attenuation, reflectance and continuity results. For harsh environments, consult local codes and manufacturer guidance for additional protective measures such as conduit or messenger support.
