1.25G Gigabit Ethernet Media Converter, SingleMode Dual SC Fiber to Ethernet RJ45 Converter for 10/100/1000Base-Tx to 1000Base-LX, up to 20-km, Pack of 2

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. Im very pleased with the affect on my hifi system.

実験的に送受信のファイバーの長さを150ｍと30ｍにして、試験してみましたが安定して動作します。 また、有線ＬＡＮを片側１００Ｍbpsと反対側１Ｇbpsにしてみても安定していました。 あとは夏を乗り切れるかどうかです。

I ordered six (two packs) of this unit and have so far used four pairs. One unit failed in about two months, another unit could not replace an existing 100 Mbps 10 year old media converter. The run distance was only 700 feet. Same unit successfully worked in a 3000 foot application. Two other units have been flawless at 600 feet and 5000 feet. Lower cost unit with not much warranty on poser supply. Lower powered laser probably to blame for one problem (bad splice) and cheap power supply for second problem.

All connections solid. Worked as described.

works great , easy setup

Works good so far. Does what I needed it to do

Just as described.

Perfect line extension.

Excellent price for the speed and ease of use.

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 thats 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.
