How to Use Outdoor Optical Receivers?An Optical receiver is a machine that receives the optical signal transmitted from optical fiber and converts it into an electrical signal for amplification. The performance of the optical receiver largely determines the performance of the whole optical fiber com
What are Outdoor Optical Receivers?With the rapid development of network communication, people put forward higher requirements for the capacity and quality of communication. The advantages of an optical communication system in cost and transmission capacity make it the main body of information super
How to Use EDFA Optical Amplifiers?EDFA refers to the erbium-doped fiber amplifier, which is an optical signal amplifier doped with Er3 + in the fiber core through which the signal passes. It is one of the greatest inventions in optical fiber communication. The main function of the EDFA optical ampl
How does the EDFA Optical Amplifier Work？EDFA is the miniaturization of an erbium-doped fiber amplifier, which is a device to amplify an optical signal. It is mainly used to compensate for the loss caused by devices and lines, so that the optical signal can propagate for a longer distance. EDFA opti
