Micafluid SF6 decomposition Transmitter for cables

Micafluid SF6 decomposition Transmitter for cables

Abstract. Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol.

  • Small form-factor pluggable transceiver - Wikipedia

    The small form-factor pluggable is a compact, hot-pluggable network interface module used for both telecommunication and data communications applications. An SFP interface on networking hardware is a modular slot for a media-specific transceiver in order to connect a fiber-optic cable or sometimes a copper cable. The advantage of using SFPs compared to fixed interfaces is that individual ports can be equipped with any suitable type of transceiver as needed. The form factor and electrical interfa
