Litech SM G.652.D Central Loose Tube Round Drop Cable is the 2 fibre unarmoured round version of our CLT (Central Loose Tube) Type optical fibre cable, a compact single-mode drop cable for FTTH and last-mile connections. Rs 40,800 per 1 km reel (2 km Rs 81,600; 4 km Rs 163,200), prices per reel and include tax. The 2 fibres sit in a gel-filled PBT loose tube, protected by two parallel galvanised steel strength members and a tough black polyethylene sheath.
