A QSFP (Quad Small Form\u2011factor Pluggable) module is a compact, hot\u2011pluggable optical transceiver used to connect switches, routers, servers, and storage systems over fiber optic links. The “Quad” in its name refers to the four independent transmit and receive channels integrated within the module. Unlike SFP modules, which carry only a single channel, QSFP modules […]<\/p>\n\n\t\t\t\t\r\n\t\t

What Is Coherent Detection?<\/a><\/h2> \n\t\t\t\n\n\t\t

Coherent detection is the foundational technology behind long\u2011haul, metro, and high\u2011capacity optical networks. Unlike direct detection, which only measures optical intensity, coherent detection recovers the complete optical field\u2014including amplitude, phase, frequency, and polarization state.
