The metropolitan area network (MAN) transmission application involves the integration, forwarding, and transmission of various data services, including SDH services and Ethernet data services. Our company has developed a high-integrated optical subsystem platform featuring modular products that consolidate multiple functionalities, such as optical signal forwarding, multiplexing/demultiplexing, optical amplification, optical line protection, optical performance monitoring, and dispersion compensation. This platform fully meets the transmission application needs of various services within metropolitan area networks.

– OEO (Optical-Electrical-Optical) Board : This board can integrate OTN (Optical Transport Network) functionalities.

– Optical Amplifier Board: This includes various types of fiber amplifiers, such as EDFA, Raman, ROPA, and SOA, enabling hybrid amplification with multiple amplification technologies for cross-segment transmission of different service types within the metropolitan area network.

– Optical Signal Multiplexing/Demultiplexing Board: This board allows for DWDM (Dense Wavelength Division Multiplexing) transmission and flexible allocation of services at various site points.

– Optical Line Protection Board: This component provides line protection for optical signals. When paired with optical performance monitoring, it effectively facilitates monitoring and operational support for the transmission system and its services.
