Hello, everyone!
In this post, I would like to share with you the difference between X40 and EX40 and their respective characteristics.
X40 Appearance of the Front Panel
X40 Application
Application Scenario 1: Multiplexing or Demultiplexing of 40 Channels of Optical Signals in the Two-Fiber Bidirectional System

Application Scenario 2: Multiplexing or Demultiplexing of 18 Channels of Optical Signals in the Single-Fiber Bidirectional System with Optical Amplifiers

Application Scenario 3: Multiplexing or Demultiplexing of 20 Channels of Optical Signals in the Single-Fiber Bidirectional System Without Optical Amplifiers

X40 Working Principle and Signal Flow

Mapping relationship between optical ports on the X40 board and frequencies

EX40 Appearance of the Front Panel
Front panel of the EX4001 board

Front panel of the EX4002 board

EX40 Application
Application Scenario 1: Multiplexing or Demultiplexing of 40 Channels of Optical Signals in the Two-Fiber Bidirectional System

Application Scenario 2: Multiplexing or Demultiplexing of 18 or 35 Channels of Optical Signals in the Single-Fiber Bidirectional System with Optical Amplifiers


Application Scenario 3: Multiplexing or Demultiplexing of 20 or 40 Channels of Optical Signals in the Single-Fiber Bidirectional System Without Optical Amplifiers
