Grommit Posted May 24, 2007 Posted May 24, 2007 Hi Can someone expalin to me please what LX and SX are in GBICS I have a Single Mode Mini GBIC module.. is that a SX, LX, LC or SC ? Is the SX, LX, LC or SC just to do with the patch lead plug or is it the type of module .. ie Mini GBIC to GBIC? How can I tell if a Mini GBIC is Single mode or Multimode ?
StewartKnight Posted May 24, 2007 Posted May 24, 2007 there are differning types of connectors (boots) on fibre, SX LX etx refers to the boot. This article will explain!

They left out the MTRJ Plug tho.. 8) Is there a difference between GBICs and Mini GBICs if you use Single Mode Fibre ? As we have a Single Mode Fibre Link and I want to know will normal GBICs and Mini GBICs do ?
Geoff Posted May 25, 2007 Posted May 25, 2007 Is there a difference between GBICs and Mini GBICs if you use Single Mode Fibre ? One will fit in your switch chassis, the other will not. Check which type your switches support and use those.

What i want to know is are there different ones if the fibre is Multi Mode or Single Mode ?
Grommit Posted May 25, 2007 Author Posted May 25, 2007 That's what the SX, LX, LC business is about. Rigt.. I thought that was the "plug" that goes into the GBIC... I heard that there are short range and long range GBIC's confused.com here
Geoff Posted May 25, 2007 Posted May 25, 2007 Time for some wikipedia i think.. GBIC is the interface standard for switches and fibre modules. http://en.wikipedia.org/wiki/GBIC SX is the 'short' distance Gigabit fibre (inter building) standard using multimode fibre. http://en.wikipedia.org/wiki/Gigabit_Ethernet#1000BASE-SX LX is the long distance Gigabit fibre (inter site) standard using single mode fibre. http://en.wikipedia.org/wiki/Gigabit_Ethernet#1000BASE-LX LH is the very long distance Gigabit fibre (site to site) standard using single mode fibre (there are more cost effective alternatives though). http://en.wikipedia.org/wiki/Gigabit_Ethernet#1000BASE-ZX_and_1000BASE-LH Hopefully Stewartkinghts earlier post with the link to pictures of connectors clears up what patch connectors you have.
Geoff Posted May 25, 2007 Posted May 25, 2007 Yeah. Anyway Grommit. It's likely you have 1000Base-SX running over multimode fibre. The only think you need to check is the grade of fibre you have.

Many thanks again Geoff...... Steep learning curve here.... So if I have single mode fibel betwwen 2 buildings and I have 2 of these http://uk.insight.com/apps/productpresentation/index.php?product_id=ZYSFPLX&nbs_search=lang%3Den-gb%26C%3D109%26S%3D1058%26K%3D%26M%3DZY Will it work ? also is there any special type of fibre patch lead between the fibre port and the GBIC... must this be single mode ?
Geoff Posted May 25, 2007 Posted May 25, 2007 Should do. You need your patch leads to be the same (or better grade of fibre). Otherwise you'll get signal loss. If there is too much signal loss, you interbuilding connection will go down.
Grommit Posted May 25, 2007 Author Posted May 25, 2007 Ok.. This is what i need LX SFP LX GBIC ST-SC and ST-LC SMF Patch Done!
Grommit Posted June 1, 2007 Author Posted June 1, 2007 Hi Geoff I have been sent 2 Multimode fibre patch leads and the main cable between the building is single mode... will these patch leads work before I open the packets to test..
