10Gtek Gigabit SingleMode Fiber to Ethernet Media Converter, Dual SC Fiber, 1000Base-LX to 10/100/1000Base-Tx Gigabit SMF Fiber SC to Copper RJ45 Ethernet Converter, UL Certified, 20km, Pack of 2

We get lightning storms more frequently, so I wanted to change my long runs to reduce possible lightning related damage (living room to the attic to the bedrooms on the other side of the house - 25-30meter runs). These made it easy and work fine over 25m of fiber. Solid metal housing, good diagnostic leds, supplied with little 5v supply.

These work great. No lag and easy to set up They make a good air gap between a modem and router for electrical events. You can use them for longer distances but that was my use case.

Works as expected

Use these all the time,,great product.

Got a pair of these t0 isolate my DAC from jitter on a Wi/Fi network by inserting a fiber optic segment. Plug and play no setup needed. Sound quality improved. Reasonably priced.

Had a lightning strike destroy 2 computers, my ISP router and my personal router Lightning traveled through the Broadband connection through the router through the Cat5 connections to destroy 2 computers via Cat5 connectivity. Go figure. This should mitigate this threat from ever happening. I realized that my APC had and RJ-11 connection to protect against a surge like that but that's after the fact. I now have the broadband connection running into my APC. But I was committed in setting this up to see if it works. It does so beautifully. Refer to the diagram it should answer all your questions.

If you are using these to create an air gap for lightning protection MAKE SURE THE TWO ADAPTERS ARE PHYSICALLY SEPARATED! DO NOT MOUNT THEM AS PICTURED IN THE LISTING! I have a 300' run between my barn and my home. Put two of these at each end of the ethernet cable to isolate the line from lightning surges. Any long ungrounded outdoor cable can act as an antenna and will attract transient voltages (static emp) from nearby lightning storms. Wanting to save space at both ends of the run, I zip-tied the two boxes together. Since they are metal cases, and surge coming down the long ethernet cable simply jumped from one box to the other. It created small tack-weld spots on all four cases where the current jumped. It fried all four adapters, and a metric crap-ton of switches downstream on either side of the bridge. In all, I lost 7 switches and these four adapters. Interestingly, I had another set of adapters downstream of the failed ones, and they did not pass it on because I'd used thick 3M VHB tape between them, and there was no contact between the boxes. Lesson learned. Certainly not the fault of the his manufacture - but rather a rookie mistake.

As of the first day of usage this seems to work properly. I’m using this with a 5m patch connector to protect my network from lightening related issues on my outdoor cameras.

何の問題も無く使えています。 コスパ最高ですね。

I was fed up with bad wifi in my outbuilding so bought 100m of dual fibre and this pair of units. Although the fibre had to take some quite sharp bends in conduit once installed I'm easily getting more than 900mbps both ways reliably so very happy. Of course I stupidly bought fiber with the wrong connectors but some cheap adapters on this site fixed that.

何回か購入してます。 複雑な設定も、スイッチでの切り替えもなく自動で繋がってくれるので便利。

I inserted these 2 units into my network, between the Cisco switch and my audio streamer. This broke the electrical connection and replaced it with a fibre optic one. This has the advantage of not transferring electrical noise from my server. I have powered the last optical receiver in this chain, not with the supplied power adapter, but with a spare 5v 1amp DC lead from my linear power supply. I'm very pleased with the affect on my hifi system.

SMC対応で安すぎませんか。。。？性能的には問題なしな感じです。どうなってるの。
