Litech Single Mode G.652.D CLT (Central Loose Tube) Optical Fiber Cable is a compact cable for aerial and outside-plant routes. 2 fibre comes unarmoured in two types, round or flat; 4, 6, 8, 12 and 24 fibre come armoured, round only. Sold on 1 km, 2 km or 4 km reels; prices are per reel and include tax. A gel-filled central loose tube is protected by corrugated steel tape, two longitudinal steel strength members and an MDPE / HDPE jacket.
