[SOLVED] TP-Link MC220L for 2.5GB ?

[lirancoh85]

Hi There,

Do you know if the Media converter TP-Link MC220L Will support a fiber internet connection of 2.5 Gigabit ? if not can you reccomend a different Media converter that can do the job ?

Thanks
Leo

That one only supports 1gb. 2.5g is rather rare since 10g costs about the same and uses the same fiber. There tends to not be a reason to run fiber at the slower rate.

What I suspect though is the fiber connection you are calling 2.5g is not using ethernet so you can't use a simple media converter to begin with. The devices you talk about are primarily used by private individuals who own all the equipment including the fiber

Almost all internet connections are using GPON. You need a modem or a router that supports this....in many cases you need very specific ones compatible with your ISP because there are many variations of GPON. GPON is very different than fiber based ethernet. GPON only uses a single strand of fiber and that fiber is actually shared between users. Fiber ethernet uses a pair of fiber that are dedicated to a single user and are point to point.

You are abseloutly right, they are using GPON. but up untill now they had a package of 1GB so the media converter (TP-Link MC220L) would work together with the SFP module that you could buy from them.
but now they have a new package with 2.5GB and I already have the asus XT8 which can support those speeds, just need to find a media converter that can handle 2.5GB.

Thanks

It is not a simple media converter. You can get SFP that would say covert optical to copper. The media converters you link just change from optical to copper the data format is ethernet on both the optical and copper links.

You now need a device to convert the gpon to ethernet. This is a function of a modem.

GPON is much more complex protocol. It function very similar to Docsis used on cable modems. It has to deal with things like signalling to control which device can talk and when.....it is a shared connection unlike ethernet. It also has encryption both to prevent people from snooping on their neighbors but to prevent people from hooking up connections without paying for them.

There are a number of gpon modems/routers that have 2.5 optical as well as 2.5 ethernet. The problem is there are small difference between ISP so you need to get one that your ISP says works. This is really something you need to search the ISP web site.

Note the asus router you link only has a WAN port that is 2.5g. You will never get that speed on a single machine because the lan port are still limited to 1gbit. You could run 2 machine at 1gbit at the same time. The other problem is there is not a lot of internet stuff that will let you transfer that fast. Many servers either only have 1gbit ports or much more likely they have artifical limits on the speed. This is to prevent someone with a very high speed internet from hogging all the bandwidth.

I would not spend extra to go to the 2.5g plan you will not see much benefit. It would be more for bragging rights.
