Lasers, LEDs and SLDs are all variations of the diode — a joined pair of silicon-based materials, one electrically positive, the other negative, containing traces of arsenic, gallium and other elements. As with other types of diodes, these devices conduct electricity in only one direction; in...
This is probably a stupid question but here it is: I am just learning concepts of LEDs. To me, it seems that there is no difference between LED and normal...
Difference Between an SLD and LD or LED An SLD is an optical device that provides output equivalent to an LD (Laser Diode) and low coherence equivalent to an LED (Light Emitting Diode), as well as a wide spectrum width. Since SLDs reduce coherence noise and enable high-precision measurement...

In Toslink, this module consists of an LED, or light-emitting diode, and a drive circuit, usually sent through plastic fiber, whereas ST Fiber Optic uses glass fiber and a red laser light at a 680-nanometer-wavelength [sources: Modern Home Theater; Toshiba]. The signal then speeds along ...

You should know the difference between an acronym and an initialism. Both acronyms and initialisms are abbreviations, but there is a key difference between the two, at least at present. Due to rampant misuse of the term “acronym” some dictionaries are now starting to add an extra definition...
Some customers want to know about the difference between multimode and single mode SFP ,so we summarize some information about multimode and single-mode.The following is some conc
