      Can SFP optical modules be used in SFP+ slots?

      SFP optical modules can be inserted into SFP+ ports in most cases. Although the specific switch model is uncertain, according to experience, SFP optical modules can operate in SFP+ slots, but SFP+ optical modules cannot operate in SFP slots. When you insert an SFP module in the SFP+ port, the spe...

      Fully understand EPON, GPON

      PON (Passive Optical Network) is a passive optical network, which means that the ODN (optical distribution network) between the OLT (optical line terminal) and the ONU (optical network unit) does not have any active equipment, and only uses optical fibers and passive components. PON mainly adopts...
