Flat Twin Ruggedised LSZH Fibre patch leads UK manufactured and tested in a controlled factory environment. Commonly referred to as “Flat Twin” Leads. With 900um tight buffered cables with aramid yarn inside 2 x 2.8mm OD individual LSZH cables (Duplex) surrounded by an additional flat LSZH sheath and 200mm length breakouts. For applications where a more robust but still flexible construction is needed such as long line applications, better protection from crushing or kinking or where frequent handling is required.

Low loss ceramic ferrule LC, SC, ST, FC, E2000 and APC connectors in duplex and simplex versions on multimode OM1, OM3, OM4, OM5 and single mode OS2 cable. Fitted with strain relief boots. Transmit and Receive legs are identified by a ring cable marker or by markings on the duplex clip.

Available with CPR EuroClass Eca or Cca-s1a,d1,a1 cable. CPR (Constructors Product Regulation) has standardised cable classes (Euro Classes) across Europe and rates how quickly cable reacts to fire spread, heat release, smoke production, acid gas production and flaming droplets. BS6701 states that as a minimum CPR class Cca cabling should be used in permanent link applications due to high flame resistance. Patch leads can be disconnected so strictly speaking they are not a permanent link. However, when they are installed inside a building in a pathway which is hidden, or where access is limited then it is considered to be an installation cable and should meet Cca-s1b, d2, a2 as a minimum. Additionally a long lead means a cable running long distance through a building just like a permanent link, so it makes good sense to specify Cca cable. See our guide to CPR EuroClasses.
