I would like to know the difference between LX and LH SFP modules. Long Haul ( LH ) denotes longer distances while Long Wavelength ( LX ) denotes less energy which is obviously shorter distance. Why does Cisco use both LX and LH for certain SFP modules?
Do they denote the capability of the module to work both for MM ( which will be Long wavelength ) and SM ( Long Haul ) fiber? Do correct me if i am wrong.
What does it infer if a modules says like "Cisco 1000BASE-LX/LH SFP" ?
