10Gtek Gigabit Ethernet Media Converter with a 1Gb SFP LX LC Singlemode Module, 10/100/1000M RJ45 to 1000Base-LX, up to 20km, with a British Power Supply

Good quality and perfect for the job at hand

I recently upgraded from a copper to an optical backbone in my home, and used these transceivers either end to convert back to the legacy copper trunks. They are easy to install, "plug & play", working well so far. Value for money was reasonable.

One of those items you never knew would be so useful! Once plugged in, it just works! No configuration required. I have used it to extend ethernet about 300m meters without issue. Another useful thing, is I use these to extend managed networks which have security embedded on - i.e. only allowing one MAC address per port. These converters don't add any MAC addresses or additional information to the network traffic, hence can't be seen by the managed network.

1st pair purchased didn’t work, 2nd pair worked flawlessly, now in use to link buildings together over 400m apart.

I needed to connect a 100Mbit/FE BTOR FTTC modem to a router which would use PPPoE. The router only had 1GbE ports that were fixed speed negotiation so I needed a media converter to sit between the two devices that supported store-and-forward. I bought the version of this converter without an SFP module so I could put a 1GbE copper RJ45 SFP module in to connect back to the router, and use the auto-negotiation RJ45 port on the converter to the modem. It has been working flawlessly for 2 weeks now.

good

Great product, very easy to use

As described and delivered promptly

I had 125' LC to LC fiber laying around that I wanted to put between my cable modem and router. I purchased two of the 1.25Gb/s SFP Module to 10/100/1000Base-Tx, with a 1.25G 850nm 550M SFP media converters and plugged one in on each side and connected the fiber. I removed my 50' ethernet cable and plugged a 3' one directly between the cable modem and media converter. I did the exact same thing on the other side and everything came up immediately. Lost a total of 5 pings, and my routers IP address did not change. (the cable modem has no idea these are in-between). As far as a performance test goes, my average ping time to my cable modems default gateway may have went up by about .25ms average over 100 packets, but that could just be the neighborhood I am in. I am more than pleased with this simple solution to protecting my network from a lighning strike on the cable lines around my house. Also - I purchased a 3rd one as well as a 10Gtek for Cisco GLC-SX-MMD/GLC-SX-MM/SFP-GE-S, Gigabit SFP SX Transceiver to plug directly into my network switch. I just trenched a 6-10" trench to my shed and will be placing the media converter in there along with an access point which is about 80' from the house plus about 35' of internal cable. I have already tested the 3rd one along with the SFP module in my switch and they connected right up. As long as I dont have any issues running the fiber, this is another great use for these to protect my internal network from both near lighning strikes as well as static differential between the buildings. While I cant take advantage of POE (Power Over Ethernet) to power the aceess point, I think the isolation definatly outweighs the benefits of POE. So far I have less than 30 minutes with these in use (2018-10-21). If you dont see an update from me, they are still working.

コスパ考えると最高です。 問題なく使えるうえ、伝送速度に問題もありません。 発熱も少なく、耐久性も現状不満無し。

コンパクトで、LCコネクタを接続するコネクタが金属でできており、光ファイバケーブルの保護的な役割をもっているので、ケーブルの取り扱いが非常にしやすいです。 大手メーカーの1/4程の価格で、コストパフォーマンスも素晴らしいです。

roon core⇄Dela S100⇄インタネットという接続の⇄のところに使っています。再生機器、NAS はDela S100に直接接続しています。 このようなオーディオ機器とインターネット、パソコンなどとのアイソレーションにはかなり有効です。音質は見違えるように良くなります。 また、SFPモジュールは付属のものから、パナソニック、ELECOM の業務用のものに変更し、デュアルモードで使っていますが、SFPモジュールによる音質差は大きいので、余裕が有れば交換をお勧めします。 再生機器とDela S100の間に使ってしまうと、この機器自体のノイズが再生機器に影響し、あまりいい結果は得られないと思いますので、そこはSonore等を使った方がいいと思います。

目的を達成できた。
