Standard for underground power distribution boxes in mines
The main electrical distribution network for an underground mine is typically 4. 6 kV, 11 kV, 12,5 kV, 13. 8 kV or even 25 kV for deep and very extensive mines. The choice of voltage is highly dependent on the load level, which is related to the depth and the size. Reference to specific products, equipment, or manufacturers does not imply endorsement by the Bureau of Mines. The application of electricity to the mining industry is a distinctive area of both mining engineering and electrical engineering. -
The fiber optic transceiver s B-end can be connected to an external switch
Short answer: Usually yes, you use them in pairs, but the “pair” can be a media converter on one end and a fiber switch (or SFP in a switch) on the other, as long as both sides speak the same speed, wavelength, and optical mode. In a fiber link, the data is transmitted from one end to another, and fiber transceivers are. The idea is to get a small switch in both the shed and in the garage too where the new optic fibre (in purple) would be plugged in. For information, the switch showed in the house (blue area) is just for illustrative purpose, I need to buy one with POE capabilities. -
