The Astrotek Telephone Cable RJ12 to RJ45 is a 2-metre long premium connecting cable designed to link analog telephony devices such as telephones, fax machines, and answering machines to standard network wall jacks with RJ45 sockets. Featuring a male RJ11 (6P4C) connector on one end and a male RJ45 (8P8C) connector on the other, this cable allows seamless connection between traditional plain old telephone service (POTS) lines and Ethernet-style wall panel wiring. Constructed with black PVC insulation and an unshielded cable type, it provides reliable signal transfer in home or office environments. Ideal for setups requiring an ADSL splitter connection, it converts incoming Ethernet signals to analogue telephony jacks, ensuring compatibility and enhanced telephony performance. Its versatile application makes it an essential accessory for telephony and DSL networking requirements.
