What is the difference between J4858C and JD118B for the JE005A

[GlobalIT]

Hello,

I have two HP Procurve JE005A v1910 switches installed in two offices. These two office are in the same building 70m apart, but the work enviroment has heavy electromagnetic interference. So I want to use a fibre connection to link them up rather than a stand ethernet cable. I have done some research and found that the SX module are more than sufficient. What I can not understand is what is the difference between the SFP J4858C 1 GBIC module and the SFP JD118B 1 GBIC module.

Thankx

You don't have a Procurve V1910, because there is no such animal; a V1910 is one of the rebadged 3Com models. I wouldn't normally nitpick about this point but it's relevant to your question.

The J4858C is what was the traditional Procurve branded part, the JD118B the former 3Com one. Some of the switches only work with branded SFPs: generally you can use a Procurve part in a 3Com switch but not always the other way round.

Unless you are keeping a common pool of spares or similar, it doesn't matter which you use.

Quite right, its an HP JE005A v1910 switch. So seeing as its a new prodcut (as in just bought) the J4858C would be the way to go for best compatability? To create a fiber link, do I need both adapters on both switches or just one each. I am still a fiber nube. :-)

Thankx

One (at each end) of either would be fine.
