![]() ![]() Patton FiberPlex FOI-2990 Fiber Optic Isolator/Converter/Modem, 8 or 12. That is, the polarization rotation due to the Faraday rotator is always in the same relative direction. It was blown to an open circuit and partly melted and the microwave still works. They join copper networks and fiber networks in just about any configuration. The vector stencils library 'Cisco optical' contains 19 symbols of optical devices for drawing Cisco computer network diagrams. Optical isolators are different from 1/4 wave plate based isolators dubious discuss clarification needed because the Faraday rotator provides non-reciprocal rotation while maintaining linear polarization. I had a surge protector on my microwave oven which did its job. Optical Isolator, Serial Port Data Switches, Multiplexer, Line Drivers,Converter - RS-232 to RS-485, Optical Isolator 2303 LH PS, Optical Isolator 2303 LH. Fortunately I had turned off and unplugged all my important electronics. Protection of electrical measuring and monitoring. ![]() I expect most of the current went to ground. Protection of especially valuable devices against hum and surge voltages from the network periphery. The tree touched a metal fence and enough of it went 150 ft up the fence to jump to my nearby power meter and fry quite a few things. I saw lightning hit a tree at the corner of my property once. Made me wonder when people tell you to get in a car during a storm as the rubber tires insulate it. They asked me to look at their computers, but it was a total loss on those. The Ethernet connection is from my local lab switch which in turn connects to another larger switch in basement equipment closet. Neighbors on a bit of hill a couple years ago had lightning hit an oak tree, split the tree, jump to the windshield of their car 10 feet from the tree, slightly melt the tires, hop from the bumper to the electrical entrance where it fried two desktop PCs, a TV and a couple other items plus their modems. ![]()
