Linkedpro EF-300-LC 300m Single-Mode Fiber Optic Cable LC/LC Duplex

The LinkedPRO EF-300-LC is a 984.25 ft (300 m) single-mode fiber optic cable drum terminated with LC/LC duplex connectors on both ends, engineered for outdoor and demanding deployments where fusion splicing is not practical or available. Built on ITU-T G.652D compliant 9/125 μm single-mode fiber with a tight buffer construction, this drum delivers low-loss transmission at both 1310 nm and 1550 nm wavelengths, making it well suited for a broad range of active optics equipment. The waterproof mechanical connection system — compatible with EFUNION waterproof connectors and supporting up to four unions — allows field technicians to extend, branch, or terminate runs without a fusion splicer, reducing deployment time and specialized equipment requirements. The ruggedized HDPE outer jacket and proven bend-radius tolerances make this drum a practical choice for direct-burial-adjacent runs, rooftop pathways, campus interconnects, and any environment where moisture ingress or physical stress is a concern.

Key features & benefits

• Single-Mode G.652D Fiber Core — Built on 9/125 μm ITU-T G.652D compliant single-mode fiber with a tight buffer of 900 μm, delivering consistent signal integrity across the full 300 m length.
• Dual-Wavelength Low-Loss Performance — Attenuation rated at ≤ 0.4 dB/km at 1310 nm and ≤ 0.3 dB/km at 1550 nm, supporting compatibility with the widest range of single-mode transceivers and active equipment.
• LC/LC Duplex Connectors Pre-Installed — Factory-terminated LC/LC duplex connectors on both ends eliminate field polishing and cleaving, providing plug-and-play deployment with consistent connector quality.
• Waterproof Mechanical Connection System — Integrated waterproof mechanical connections and support for EFUNION waterproof connectors allow up to four field unions along the run without fusion splicing, protecting against moisture ingress at every junction.
• No Fusion Splicing Required — The mechanical connection design enables full deployment and extension in the field using only hand tools, significantly reducing the equipment and skill threshold for installation crews.
• HDPE Outer Jacket — A high-density polyethylene outer jacket measuring 5.4 mm in external diameter provides durable protection against UV exposure, abrasion, and environmental moisture across a wide operating temperature range.
• Wide Operating Temperature Range — Rated for operation from -20°C to +60°C, this drum is suitable for installations across variable climates, from cold-weather outdoor runs to warm equipment rooms and rooftop pathways.
• Controlled Bend Radius Specifications — A minimum dynamic bend radius of 30 mm and minimum static bend radius of 20 mm allow for tight routing through conduit, trays, and junction boxes without risking fiber integrity.
