The product itself is great. Everything that you need for FTTH deployment. As normis said, it has to be simple, to keep the price low.
We have lots of places where this will deploy outside customers premises and bolt on directly to existing Ethernet installations. The design is great and it happened to be made by MT!
I'd only like to suggest adding some holder for fiber splice inside the enclosure. These boxes will mostly terminate long fiber runs, so having a separate termination box and using short patch cord is less practical and elegant than keeping everything in one PoE powered box. Sure there are ready made drop cables with connectors already in-place, but they are more expensive, bulky and less convenient to work with. At least some strong fixation of entering fiber would be nice, like zip-ties or something similar.
Also, it'd be nice to have different versions of this product, for example: FTC11G with integrated 1.25gbps/1310TX/1550RX module, FTC11FE - with 155M/1310TX/1550RX module, FTC11S - with SFP slot just as it is now. Just a suggestion though
