Hey guys,

I have a question, I was looking at the advanced setting in my network card and I see there is a setting for something that I know nothing about. It's Gigabit Lite option. What is this and what does it do?

it's buried way down on this spec page

http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PFid=5&Level=5&Conn=4&ProdID=349

Supports Giga Lite (500M) mode

can't find any info on what the advanatages are (presumably either longer cable runs or possibly using less pairs)

Interesting to know.

I found some references to GIGALite being a "Solution" developed by Alcatel prior to the finalization of the original Gigabit Ethernet (IEEE 802.3z) back in 1998. It seems the draft standard allowed a maximum run of 220m on what was at the time the standard fibre cabling in most existing installations, and it appears that GIGALite was a new type of fibre developed allowing longer runs.

I'd say it's safe to say it's a completely redundant legacy setting in those drivers :-)
