The sensing of critical multiple parameters like high pressure, high temperature (HPHT), chemicals, etc., are required at longer distances in real-time. Optical modulators are devices that modify the properties of light, such as its amplitude, phase, frequency, or polarization, in response to an external signal. Light is confined to the core by total internal reflection at the boundary between the core and cladding (which has a lower refractive index). Use Case: Long distance, campus backbone, datacenter interconnect. SFP (Small Form-factor Pluggable) optical modules are compact, hot-pluggable transceivers that enable network equipment to connect seamlessly to fiber and copper links. It is also known as a small form-factor pluggable or mini GBIC.
