The 3 x SMOF, duplex patch cords with LC UPC Grade “B” connectors of length 10m, has a LSZH sheath as standard. Each fibre cord is Ø2.0mm. The SMOF meets G652D specification, with no water peak in the wavelength profile graph. These ruggedized patch cords can withstand up to 6 full turns (360°) twists over a one meter length, without causing any significant increase in attenuation. However for best performance when using the ruggedized patch cord, full twists are best avoided. A single optical fibre cord has the following features: minimum tensile strength of 100N; an MBR of 30mm; ability to withstand a small crushing load; ability to withstand a small impact load; and ability to pass a standard edge bend test. Also supplied are 12 off, red coloured, SC through adaptors, that are used to indicate the optical fibre is directly spliced through, and does not have a connector connection at a patch panel.
