J-2Y(ST)Y ST III Bd | ISDN Cable
Item descriptions
| Application: | This Integrated Services Digital Network (ISDN) cable is to be used as a termination and connection cable for the transmission of analogue to digital signals up to 16 MHz. It is suitable for ISDN applications in this frequency range such as BTX or fax. Peculiarities of this cable are the cores which are stranded to star quads. |
| Construction: | 1.....solid bare copper 2.....core insulation of polyethylene (PE) 3.....layer of plastic foil 4.....overall screen of plastic laminated aluminium foil with a tinned drain wire (Ø 0,6mm) 5.....outer sheath of polyvinylchloride (PVC), grey |
