MC220L Gigabit SFP Media Converter, 10/100/1000Mbps RJ45 to SFP, IEEE 802.3ab/3z Compliant, FX Port Support Hot-Swappable, Auto-Negotiation, Distance Up to 100m

Easy setup (data pass through) No config, it just works! Would love a 2.5Gb version

Used for fibre we've run between the house and garden office. Works excellent

Excellent, using in an optical convert for my hifi. Brilliant

Purchased as part of project to give Gb connectivity to remote building 40 m from house using multimode fibre allowing me to mirror remote server with one in house, unfortunately due to various family matters etc abandoned for over 3 yrs but now want to have IP phone in building together with aforementioned server(s) - eventually. Hooking up entire system on bench, fibres and media converters noticed that the MC220L will NOT negotiate with a 10/100 Mb interface port such as the Yealink T21P E2 phone uses (another Yealink the T23G I have is Gb although I did not test this). Fortunately I had as part of my original project purchased a TP-Link SG2216 16 port switch which has 2 SFP combo slots for the laser modules - was going to use at the house end originally, this worked with the Yealink OK. I did read about the problem with connecting only to a Gb port somewhere else, I did try another TP-Link 10/100/1000 switch in between the unit and phone but this didn't work

Turns out, the fibre itself is stupid cheap these days. Particularly OS2. I was quite shocked to find out that it's cheaper than Cat 5e. Copper price and everything. What's great about OS2 and not so great about OM(whatever) is that a single strand of fibre can do duplex. Pretty much like any full fibre ISP, albeit without the passive element. I'm also quite unfortunate that the only decent way of routing my networking is underneath my kitchen furniture. By itself isn't a problem until that realisation that high power appliances, such as an oven or an electric hob may pose some challenges to the feeble ethernet that's prone to inductive currents. While shielding and grounding is a thing, there are limits to how close one can safely get next to a high voltage line. That's great about light: it doesn't really care about EM interference. You can't induct a current in a plastic core in a fibre. Add a couple of duplex SFP receivers (they can be found pretty cheap elsewhere). These BiDi receivers use 1310/1550nm light for RX/TX and they are sold in A/B pairs as the TX wavelength one one side is the RX on the other and viceversa. Cue this media converter on one side and Ubiquiti equipment on the other. It works as expected with ONTi transceivers and devices such as UDM Pro or ER-X SFP. Essentially, this enabled me to use fibre as my home core networking. The beauty about OS2 is that I only need to upgrade the transceivers to suport SFP+ if I ever need something like 10 gigabit or more. For the time being, benefitting from the economies at scale for fibre gigabit, this shall do. So far, I can't fault this media converter. It even worked with a RJ45 SFP adapter, albeit that was for testing purposes as something acting as a two port switch is kinda silly.

Arrived quickly and was perfect for my needs

Does the job perfectly, converting 1000BASE-SX fibre into 1000BASE-T gigabit Ethernet. It doesn't come with the SFP transceiver required for this so you'll need to get your own (this is the Full Duplex model) but yeah, it works great. Built solidly.

Bought to use with a BT leased line fibre connection. This sits after thr BT ADVA unit and converts to 1gbps ethernet into our firewall. Maintains full speed from the ADVA and doesn't generate much heat.

Does what it says. If used for audio/streaming be sure to use a linear powersupply or a power bank with a 9 V upscale cable.

Funktioniert problemlos mit verschiedenen Modulen und in verschiedenen Netzwerken. Gut geeignet, wenn man am Glasfaseranschluß den eigenem Router betreiben will. Günstiges Gerät, das sich schnell und einfach in Betrieb nehmen lässt.

このたびは、色々とありがとうございました。梱包、スピード、勿論商品も満足しております。私事ですがネットがバグトラブルでした 、また機会があれば宜しくお願いします！

converter is very unstable and only give 1gbps when restarted - it automatically defaults to 100mbps i tried all cables and patches , same issue do not buy

Very good
