This is nothing more than an Ethernet pass-through. All will be fine as long as the fiber connection back to the switch carries the correct VLAN information; however, this does not provide POE, so a camera will not be powered. To handle 4K video, a 1GB connection to the switch is more than enough.
Yes, the unit includes a power adapter as well as an AC power cord that can be removed.
It's possible - The IP camera will be connected via ethernet, and fiber will be run from the other end of the media converter to your switch, if it can accept fiber, or to another media converter, if it can accept ethernet. The goal is to run a wire that is at least 100 meters (330 feet) long.

I had a 125' LC to LC fiber that I wanted to connect my cable modem and router with. br>I bought two of the first ones. SFP 25Gb/s to 10/100/1000Base-T Adapter Tx, and it's a one. I used two 25G 850nm 550M SFP media converters, one on each side, and connected the fibers. I disconnected my 50-foot ethernet cable and connected the cable modem and media converter directly with a 3-foot cable. On the other side, I did the exact same thing, and everything appeared right away. My router's IP address did not change, but I lost a total of 5 pings. (The cable modem is completely oblivious to the fact that these are connected. ) between). br>In terms of a performance test, I believe my average ping time to my cable modem's default gateway has increased by about. Over 100 packets in 25ms, but that could be due to my location. br>This simple solution for protecting my network from a lightning strike on the cable lines around my house has exceeded my expectations. In addition - br>br> I bought a third one, as well as a 10Gtek for the Cisco GLC-100. MMD/GLC- MM/SFP- S, Gigabit SFP SX Transceiver that I can plug into my network switch directly. I recently trenched a 6-year-old girl. I'm digging a 10" trench to my shed, where I'll install the media converter, as well as an access point that's about 80' from the house and 35' of internal cable. I've already tried the third one with the SFP module in my switch, and everything worked fine. This is another great use for these to protect my internal network from both near-lightning strikes and static differential between buildings, as long as I don't have any issues running the fiber. While I won't be able to use POE (Power Over Ethernet) to power the access point, I believe the benefits of isolation far outweigh the advantages of POE. br>br>I've only spent about 30 minutes with these so far (2018-). 21). They're still working if you don't get an update from me.
In my opinion, these 10gTek media converters are missing two key features: the ability to choose from a number of different auto-pilot options They don't propagate link state from copper to fiber or vice versa, and they don't negotiate or force duplex settings. Whether you like it or not, it's a fact of life. Many service providers impose speed and duplex limits on their connections. If you don't have the ability to force these settings, you'll have to make do with what you My service providers would not be able to use these converters. If you're simply connecting two of these devices to travel a short distance- Then you're probably fine; however, if you want to work with other devices, you'll need to upgrade. There's a chance you'll have issues. br>br>The second issue, in my opinion, is far more serious. These converters appear to have been implemented as a two-port switch by 10GTek. That means you can plug a cable into the RJ45 connector and get a connection even if the fiber is down (or completely disconnected). If you need to track the status of an interface for something like HSRP, or if you need BGP to fail over immediately because a link has gone down- You're not going to be able to do anything about it. Before your BGP session can fail over, it will have to time out, which isn't ideal. In addition, interface tracking will not work. br>br>Another option is to look into the TRENDnet TFC- TFC or 1000MGA Instead, 1000MB is used. Both of these devices are capable of accurately relaying link state from copper to fiber and vice versa. If there's a problem with the fiber, The copper interface is going to be unavailable. If there is a shortage of copper, The fiber interface is going to be unavailable. You can also set the speed and duplex manually or let it do it for you. a discussion.
This fiber media converter was purchased to establish an ethernet connection between an underwater remotely operated vehicle (ROV) and the controller at the land station. For me, the fiber solved some problems caused by UTP. The fiber carries three camera signals as well as a control connection. This media converter was chosen because it was affordable and had the LC connectors I needed. The fact that it was so small was also crucial. I took the case off so I could squeeze the media converter into the mini switch with ease.
I compared them to the duplex (two-cable) version and found that they performed similarly, indicating that the half-duplex protocol is not the bottleneck, but rather the 1Gbps limit. Full duplex will not fail over to one fiber if the other fails, according to the vendor. So, with a two-fiber cable, I pull the cables out of the clip and run one strand while saving the other for backup. I was very pleased with it, and it has now been several weeks since I received it. I should also mention that the vendor is very helpful. Third-party vendors and look-alike boxes exist, but I am unable to comment on them.
It has a movement rating of one. My internet speed is 300 mbps, but I tested it with 600 feet of single mode duplex fiber optic and it only moves 75 mbps. br>I assumed it was my fiber optic, so I went to an electronics store and bought a 9-meter fiber optic patch to test it, and the results were the same. br>The speed was 75 to 80 mb/a, which was exactly the same as the 600fts fiber optic cable, indicating that the problem was with the converters rather than the cable. br>Hopefully, this information will be useful to other buyers.
That said, this is the first time I've used one of these and it came with a bad SFP module out of the 5 or 6 times I've used them. I was fortunate in that I had another one with me on the job.
It delivers on its promise. I got around 930 Mbps through it, which is about the same as what I get with a standard 1000BASE-T connection. The metal case is one of my favorites. However, the price isn't the best; you can get one without an SFP transceiver and purchase one on eBay. Cheap ones are plenty fast, and I found a 4Gbit one for under $2, including shipping. The TP- The Link alternative is nearly identical, with the exception of the metal case, but it is less expensive if you use your own transceiver.
