SFP Optical Module Wavelength Classification

- Sep 01, 2018-

According to wavelength 850nm/1310nm/1550nm/1490nm/1530nm/1610nm, wavelength 850nm for SFP multimode, transmission distance below 2KM, wavelength is 1310/1550nm for single mode, transmission distance above 2KM,

The price of these three wavelengths is relatively cheaper than the other three. Naked modules If not identified is easy to confuse, the general manufacturers will be in the color of the pull ring to distinguish, such as: Black pull ring for multimode, Wavelength is 850nm, blue is wavelength 1310nm module, yellow is wavelength 1550nm module, purple is wavelength 1490nm module and so on.
