Replacing modems with SFP modules

[System Error Message]

Hi I'd like to replace my VDSL modem with an SFP module to do the translation using my network switch instead. The purpose of this is to minimise the number of devices turned on 24/7 and to use more reliable hardware since my switch uses store and forward switching with error correction capabilities.

Is there an rj11 VDSL SFP module?

I've seen single mode bi directional fibre optic SFP modules which would seem compatible to the cables used by FTTH ISPs but would it be possible to use such modules to replace the modem for internet connectivity instead of only point to point connections.

Is there an SFP module that's compatible with virgin media's fibre optic cable?

It would be significantly faster, better and energy efficient to use an SFP module on a high performance switch rather than the modems that ISP give. For reference, my modem uses a constant 15W and my managed switch also uses 15W but has a max rating of 29W (measured with a kill-a-watt meter)

The SFP footprint is much too small to fit all the electronics and support components required to implement VDSL2 so I doubt this actually exists. The smallest possible footprint is likely around three times the SFP size simply due to the isolation transformer and analog filters.

If your switch supports some form of option modules or cards, VDSL2 might be one such option that could be available as an add-on. Unless you have a modular switch/router though, this is unlikely to be an option.

Highly unlikely it will be cost effective. Just the cost of the SFP itself will take you a long while to recover looking at power utilization.

You will always likely need some kind of modem. Even though it may look like a ethernet fiber it likely is running something else ie dsl on the fiber. If they could just run gig-e to your house it would be so much easier for them. There are so many ways to do this it is hard to say. I know verizon fios runs 3 different colors of laser on their SFP so they can carry data and cabletv on the same fiber. This of course makes the SFP extremely expensive.

with a fibre optic ISP, replacing a modem that is out of warranty can cost $200 with the ISP. Although i dont exactly have any mulfunctioning modems, fibre optic ISPs lock you out the modem. Unlike an actively cooled switch or a passive switch with big heatsinks, consumer modems are very likely to overheat or run very hot in hot countries.

My modem is locked by the ISP so i cant access any configuration settings that would let me modify the firmware or change any settings that would make it more effective and use less power by disabling unnecessary things.

If the ISP uses some other form of communication over fibre optic, wouldnt it be more software related than the translation hardware?

The VD SFP is not just a sample now, but had been production.

Seems to be more solutions coming out however a lot of VDSL modems and sfp modules only go up to 100Mb/s while the VDSL2 standard can currently go up to 200Mb/s. Since i last posted this i now have a router that has SFP+ slots which would definitely do better than any modem if it had a SFP module instead of having to use a modem that needs to be restarted once every 3 months.

One of the latest replies however shows an SFP module that can work at max speed through great distance so it is something to consider.
