Ericsson TSR9010481/x R1F 4m GJUL4/TLU MDF 120 Ohm connection cable.
The Ericsson TSR9010481/x R1F 4m is a GJUL4/TLU Main Distribution Frame (MDF) connection cable designed for 120 Ohm balanced line termination. This 4-metre cable provides the physical interconnection between telecommunications equipment and the MDF, ensuring proper impedance matching for signal integrity.
This cable is used within Ericsson telecommunications infrastructure, typically in fixed-line exchange environments where balanced copper connections are required. The 120 Ohm impedance specification indicates use with European-standard digital transmission systems, commonly found in E1/ISDN and similar applications.
As part of Ericsson’s legacy fixed-network portfolio, this connection cable supports older but still operational exchange and switching equipment. It remains relevant for maintenance, expansion, and refurbishment projects within existing Ericsson installations.
