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

These worked, and were delivered on time.

I bought the double pack in July and one of them already quit working.

Sent the wrong product to begin with. Now we install the correct product and it doesnt work.

I patched this converter between my ISPs cable modem/router and my home theaters Ethernet switch to break any electrically conductive path between them. This cheap insurance should give me the peace of mind that in the event the cable modem gets zapped, it wont take my rig down with it. It was plug and play right out of the box-quick and easy to hook up, and no software to install and configure. Some say doing this improves audio performance too. I dont see how, but the claim might be legit; since Ive done this, overall sound seems somewhat clearer.

I used it to replace a failed poe switch (after 2 years) from another manufacturer. Hopefully this one will last longer

All connections solid. Worked as described.

Bought this to place between ISP modem and internal network managed switches/devices. Pretty much plug and play. Purchased the 1M BeyondTech SC/UPC to SC/UPC A/B fiber patch cable. A/B connects where A is in RX on both devices and B is in the TX on both devices. Plug in power, connect one RJ-45 to ISP Modem and one RJ-45 to internal managed switch. No change in ISP speeds. 16ms PING from San Antonio to Ft. Worth, 230mb/s download (200mb/s purchased) and 12mb/s upload (10mb/s purchased). No drop in throughput and truly plug-n-play simplicity. Did this as a test for my personal office will now do the same for the house. Also will look at getting fiber optic in length to run between main switch at the house and remote rooms that while WiFi works, hard-wired would be so much better.

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 live in an area that frequently sees strong lightning storms, and the cable system often delivers high-voltage surges on the coax that not only fries the modem, it often goes on (across the ethernet cable) to fry connected routers, switches, etc. on the network. Thats a big pain to deal with, never mind expensive. The fix: this kit plus a short (2m) loop of fiber creates an effective air gap that stops those surges from zapping the rest of the gear. Of course, one of the media converters could get fried itself, but thats cheaper than the rest of the gear. It is totally plug and play between my cable modem and the router.

I use this product to replace my failed units install for a few years and they work very well. I recommend them to anyone needing a replacement for your environment.
