Working principle of Streaming modules

2

A Streaming topology can be developed and compressed into a JAR file by using Storm APIs or referring to the CQL syntax manual. After the topology is submitted to the Streaming cluster, Nimbus automatically assigns it to the Supervisor node for processing. The topology logs can be viewed on the UI through the port provided by Logviewer.

Working principles of DCM optical modules
After an optical signal is transmitted over a certain distance, the optical signal pulse is widened because of the positive dispersion accumulated during line transmission, seriously affecting the system transmission performance. Using the passive compensation method, a DCM uses the negative dispersion of optical fibers to offset the positive dispersion of transmission fibers and therefore compresses signal pulses. According to different implementation principles, DCMs are classified into two types: DCMs using dispersion compensation fibers (DCFs) and DCMs using fiber Bragg grating (FBG).

Working principle of a DCM
After an optical signal is transmitted over a specific distance, the optical signal pulse is widened because of the positive dispersion accumulated in the system. As a result, the system transmission performance is seriously affected. A DCM is a passive device using a dispersion compensation fiber (DCF). With a DCM, signal pulses are compressed because a DCM has inherent negative dispersion that can offset the positive dispersion of the transmission fiber. According to implementation principles, DCMs are classified into two types: DCMs using a DCF fiber and DCMs using fiber Bragg grating (FBG).
