Hello everyone,
at some point I dumbly decided to just pull a copper CAT7 to some locations, not planning ahead enough to use fibre. Well, upgrading my system to a star topology with 10G Uplinks, Since all it’s Mikrotik, I went with the S+RJ10s, but they are getting quite warm so that they would trigger the switch to run the fan at full speed, which might be a bit loud. Does anyone have any recommendations for RJ45 SFPs that would stay under the 65°C threshold of the Switches?
in general these modules always heat up a lot. I don’t think there’s anything that stays cold
If I recall correctly, a fiber SPF+ is around 1 W or less and a copper one around 3-4W.
This increased amount of power has to go somewhere (heat).
AFAIK all copper SFP+ will go 70° or more.
Depending on a number of factors it is possible to better the cooling of the spf with heat sinks and optionally with added small fans, see as an example:
http://forum.mikrotik.com/t/sfp-module-is-extremely-hot/117746/1
fs.com have a few rj45 sfp+ modules.
They range in power consumption from 1.8W to 2.9W
Apparently the S+RJ10s is around 2.7W, so the 1.8W one might be good.
(but quite pricey)
Sorry I don’t know how well or hot it works, or if it will work with a Mikrotik.
though fs is usually well supported
To cope with heat issues, many vendors recommend spacing SFP+ modules (ie not placing SFP+ modules side-by-side or one over another one).
IMHO, a 2.5 or 5Gb/s module avoiding heat production would make a lot sense on the market, if such module could be designed.
FS.com modules are supported well as far as i observed. at least all SFP/SFP+ modules (MM, SM, RJ45) worked in RB1100x4AH, RB4011, CCR2004, CCR2116 and hEX S
