Introduction

Introduction

  • Clock cable for a common MPU/SRU

    One end of the clock cable is an SMB connector connected to the clock interface on the SRU/MPU and the other end is connected to the clock interface on an external device. The connector on the other end needs to be prepared as required on site.

    There are two types of clock cables:

    • 75-ohm clock cable

    • 120-ohm clock cable

  • Clock cable for the 1588v2-supporting SRU/MPU

    A clock cable is used to connect the clock interface on the NE40E to the clock interface on another device. In this manner, the NE40E can receive 2 Mbit/s clock signals, 2 MHz clock signals, 1 PPS +ASCII time signals, 1 PPS+RS232 time signals, or two channels of DCLS time signals from the upstream device and provides 2 Mbit/s clock signals, 2 MHz clock signals, 1 PPS +ASCII time signals, 1 PPS+RS232 time signals, or two channels of DCLS time signals to the downstream device.

    One end of the clock cable is an SMB/RJ45 connector connected to the clock interface on the SRU/MPU and the other end is connected to the clock interface on an external device. The connector on the other end needs to be prepared as required on site.

    An SMB connector is used together with the 75-ohm coaxial cable whereas an RJ45 connector is used together with the 120-ohm trunk cable.

NOTE:
The wire sequence of a trunk cable used as a clock cable differs from the wire sequence of an ordinary twisted cable.
