all you should need to do is replace the Allied Telesis AT-MC101XL with Gb fibre converters such as Allied Telesis AT MC1008/GB Media converters
What type of fibre is it? OM3?
You just need to swap the fibre cable and cut out the media converters completely. I'm guessing you're using an ST to ST cable at the moment (black and red each ends). One end connected to your fibre patch panel and the other end the media converter.We have a couple of Cisco Small Business SG 102-24 gigabit switches w/ 2 x combo SFP set up, if that's any use.
By swapping the cable to an ST > LC, you can then go from your fibre patch panel, directly to your fibre SFP module.
Of course I would double check all this, but it's easy to do and the cables are relatively cheap. Most likely you're going to need either an OM2 62.5/125 (normally grey) or 50/125 (normally orange).
Brilliant responses, thank you very much.
The buildings are pretty close, maybe 20m apart (plus internal distance).
It's currently an orange cable, black and red at each end.
Would I be correct in buying 1M Fibre Optic LC-ST Multi Mode Patch Lead 50/125 OM2 from eBay? It seems almost perfect, but does the LC end fit directly into the Cisco SFP or do I need a converter? I'm a bit thrown by calling the same thing SFP and LC, if they are.
The converters look to be about €100 after delivery, so ideally the eBay link will do.
It's less than fun trying to map out networks other people have set up! There's at least one room and one mystery port that I haven't figured out yet (no, they don't match!).
You will need a module from Cisco to insert into the SFP port on the Cisco switch. The LC-ST cable would then plug into the module in the SFP slot.
You also need to make sure that the fibre patch lead you buy is the same sort of fibre as the "backbone" cable... e.g. 50/125 or 62.5/125.
Which is usually printed on the cable if you can get to it.
More than likely (as the cable's orange), you'll need an LC > ST 50/125 cable, but as others have stated it should be printed on the cable. I have come across some installations however where it's very difficult to tell, but normally you'll be able to tell from at least one of the patch cables.
You'll also need a GLC-SX-MM module for each switch, but please check compatibility before buying them!
2 x GLC-SX-MM
2 x LC > ST 50/125 cable
It should then connect automatically once both ends are connected. If not, then check the cables are properly connected. Hope this helps!
(We have some orange 62.5/125 and when I started some miss matched patch cables) The only real way to know is read what's printed.
Why are the modules so cheap on eBay? The usual website I order from (where I got the switches) prices them at €300, while second-hand ones start at £20 on eBay. Have people moved to 10Gb? I was planning to order some non-Cisco branded ones because they guy offers expedited shipping, or Cisco branded ones if you question the compatibility.
Thanks again for the help.
Make sure the GLC-SX-MM module is compatible with your switch.I'd just like clarification on "please check compatibility"
Modules are cheap as they may have been pulled from existing networks (due to upgrades to 10G), or course a lot of companies are going bump, so sometimes IT hardware is sold online to the highest bidder.
10G is still very expensive and it's very difficult to max out a 1Gbps connection. If you can, then teaming is the next option, supporting upto 8Gbps, for a fraction of the cost of 10Gbps.
