GFP optical module general purpose

The optical module serves as a crucial component in optical fiber communication systems, operating at the physical layer, which is the lowest layer in the OSI model. Its primary function is to achieve optoelectronic conversion by converting electrical signals into optical signals. Generic Framing Procedure (GFP) is a multiplexing technique defined by ITU-T G. This allows mapping of variable length, higher-layer client signals over a circuit switched transport network like OTN, SDH / SONET or PDH. As the core optoelectronic devices operating at the Physical Layer of the OSI model, their primary function is to perform electro-optical and photo-electric conversion during signal. Reporter genes are widely used to quantify promoter activity, which controls production of mRNA through the interplay with RNA polymerases and transcription factors.
