Outdoor optical cable electro base MD-UT-8F-3987-40m — 8-fiber single-mode, 5.5 mm, 40 m

Outdoor optical cable electro base MD-UT-8F-3987-40m — 8-fiber single-mode, 5.5 mm, 40 m is a 40-meter single-mode fiber optic cable with eight glass fibers in a 5.5 mm outer diameter jacket. Engineered for outdoor use, the cable features a weather-resistant outer sheath and a construction suitable for installation in ducts, conduits or aerial spans. It provides low-loss transmission for long-distance signal transport, making it applicable to telecommunication links, CCTV backbones and fiber-to-the-home (FTTH) distribution segments.

Advantages

The cable combines a compact 5.5 mm diameter with an 8-fiber single-mode core to balance capacity and ease of handling for external runs. Its outdoor-rated jacket increases resistance to UV exposure, moisture and temperature variation, while the fiber design ensures low attenuation for extended distance transmission. The cable is manufactured for straightforward installation in constrained pathways and supports standard single-mode connectors and splicing practices.

Suitable for

• Long-distance telecom links and network backhaul
• CCTV and video surveillance backbone connections
• FTTH distribution and last-mile fiber segments
• Duct and conduit installations or aerial deployments

Key specifications

• Fiber type: single-mode, 8 fibers
• Outer diameter: approximately 5.5 mm
• Cable length: 40 m
• Jacket: outdoor-rated weather-resistant sheath
• Attenuation: designed for low-loss single-mode transmission (typical values depend on wavelength and installation)
• Installation: suitable for duct, conduit and aerial routing

How to use

Prepare cable ends by stripping the outer jacket and buffer layers according to standard fiber handling procedures, keeping fibers clean and protected. Terminate fibers with appropriate single-mode connectors or perform fusion/splice joints to patch panels and distribution hardware. Route the cable along ducts, conduits or aerial supports, securing it with compatible clamps or ties while avoiding sharp bends and excessive tensile load. Follow local regulations and safety rules for outdoor cabling and, when necessary, perform testing with an optical power meter or OTDR to verify attenuation and continuity after installation.

Usage recommendations

Store and handle the cable in dry conditions before installation; avoid prolonged exposure of cut ends to contamination. During installation maintain the minimum bend radius recommended for single-mode fiber and limit pulling tension to the cable’s rated maximum. For long-term outdoor performance, ensure end terminations are sealed against moisture and perform periodic inspection of aerial supports or duct entries.
