Tenda TEG1050F, 48 Port Gigabit Switch

Tenda TEG1008M, Sold by: Tenda Official for $15.99 on 3 March 2025. My reviews are always 100% honest personal opinion on the itmes I purchase for my personal use, I do not receive any compensation, money nor any item for my reviews...EVER! I have 9 of these things and on one leg of my network, these are nested 5 deep. I have a complicated network due to the layout of the home and locations of devices not to mention 12 security cameras sprawled out over 300 linear ft long by 150 linear feet wide. For example, this one leg has a 50ft ethernet cable from the router to switch1, 100ft to switch2, 100ft to switch3, 200ft to switch4, and 50ft to the final switch5. Each switch has devices connected to it as well as the cable to the next switch. At the end of that chain are two security cameras. My longest ethernet cable is 200ft and these switches work just fine. Lets talk LIGHTNING. This is a topic I can talk for a long time about so I will try to keep it as short as possible but still get a couple points across. Country living brings along with it many nuisances. Here we have bad lightning storms at least once a year. None of the electrical nor electronic devices in our home can survive a direct strike (I don't know of any consumer grade equipment that can). If your home is prone to direct strikes you will have significant damage and I highly recommend consulting an expert to prevent that in the future. Once that is prevented, the lightning threat then can come from two avenues, namely power grid and near strike. Defending the power grid lightning threat is as easy as ensuring a fantastic ground where the mains comes into the house. The top wire on aerial mains runs is there for lightning protection and was originally connected to a ground rod at every pole. That is until somebody comes along and steals the wire to sell for a couple of bucks. That leaves the grid wide open and every home and device on it vulnerable to power line lightning strikes (surges). If you are having problems with this, ensure your house mains ground is strong (buried mesh with salt and 8' deep ground rods at every corner of the mesh) and consider using a whole home surge suppressor as well as individual surge suppressors. Once mains entry ground is secured, that leaves near strike as the remaining threat avenue. The Electro Magnetic Pulse (EMP) emanating from a lightning strike can be HUGE depending on the proximity of the strike and the current discharge in the strike. This pulse will couple with long wires such as USB, HDMI and ethernet cables even if they are 99% shielded. If the devices on either end of these cables are not protected, they will be destroyed. I have lost many USB devices, ethernet devices and HDMI devices over the years due to this phenomena destroying the chips connected to those ports. And many times, the device will fully fail a month or so after the fact. In other words, depending on the near strike I have had immediate failures but much of the time the failures are delayed. Voltage sensitive devices (e.g. transistors) can be instantly made nonoperable or weakened exhibiting delayed but premature (given it's MTBF) failure. After a bad lightning storm comes through we have and will continue to see devices prematurely fail within a month. So I for one greatly appreciate TENDA advertising that these switches have lightning protection. Most switches do not advertise lightning protection whether they do have it or not, so I am glad these do. I have a few of these mounted outdoors (under a roof or in a non temperature controlled shed). In those cases I fill the open ethernet ports with silicone RJ45 Jack Dust Covers. I also squirt synthetic silicone grease (dielectric tuneup grease e.g.) in the populated ports. 6kV should be sufficient to protect against ethernet cable line transients due to ESD or near strike EMP induced spikes. If any of these ever fail, I will edit this review and let you know. I appreciate the unmanaged plug and play, jumbo frame support, durable metal enclosure and quiet fanless design. Hope this helps.
