7.6 Clock Cable
This section describes the structure and technical specifications of the clock cable.
7.6.1 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.
