OEO (Optical - Ethernet - Optical) Optical Amplifier
OEO optical amplifier is a device used for gaining optical signal in optical fiber cable to compensate the attenuation of optical signal during transmission, so as to convert the non-relay transmission distance in coupling to realize long-distance transmission of optical fiber interconnection.
OEO optical amplifier, also known as OEO repeater/converter, is a protocol and rate transparency that uses OEO (ie "optical-electric-optical") technology to regenerate, amplify and shape signals during optical transmission. The effective optical fiber converter is also the earliest optical fiber amplifier. It can effectively save fiber resources and networking costs, so it is widely used in various long-distance network transmissions.
The role of OEO optical amplifier
OEO optical amplifiers can replace optical power amplifiers, effectively solving the problem that the transmission distance of optical fibers exceeds the transmission distance capacity of the equipment. At the same time, it can be used for wavelength and mode conversion in optical fiber interconnection, and can realize seamless integration of different fiber types, and cooperate with other network equipment. (Such as DWDM, OADM, DCM, EDFA, etc.) to build a complete optical network transmission system.
Principle of OEO Optical Amplifier
The OEO optical amplifier converts the received optical signal into an electrical signal, and then transmits the optical signal through the optical transmitter through circuit processing.
Types of OEO optical amplifiers
Taking FS as an example, there are two types of OEO optical amplifiers: 10G OEO and FMT 4DL-OEO 10G SFPA.
