Review on GESD Universal Telecommunications Engineering Maintenance by Lild Zimmerly

You are a network engineer. You work alone. You can't be in two places at once, so turn on this device, connect it to a fiber optic cable and walk 200 feet to your destination. No light on fiber. Ah ha! So this is fiber! Perfect. Then you call your boss and they call him. You will return to the original website and the device will turn off. You move it and the device turns on again. A NO! do you wanna tell me So you twist the lid and the device goes off, then on, then off. This thing is absolute garbage!
