Introduction to pluggable transceiversAt present, four types of pluggable transceivers are commonly used, and they can bedivided into optical transceivers and electrical transceivers based on transmissionmedia as shown in Table 3-1.Table 3-1 Commonly used pluggable transceiversTransceiver type AppliedenvironmentWhether can bean opticaltransceiverWhether can bean electricaltransceiverSFP (SmallForm-factorPluggable)Generally used for100M/1000MEthernetinterfaces or POS155M/622M/2.5GinterfacesYes YesGBIC (GigaBitInterfaceConverter)Generally used for1000M EthernetinterfacesYes YesXFP (10-Gigabitsmall Form-factorPluggable)Generally used for10G EthernetinterfacesYes NoXENPAK (10Gigabit EtherNetTransceiverPackage)Generally used for10G EthernetinterfacesYes YesNote:For pluggable transceivers supported by S3610 & S5510 series Ethernet switches,refer to H3C S3610 Series Ethernet Switches Installation Manual and H3C S5510Series Ethernet Switches Installation Manual.II. Identifying pluggable transceiversAs pluggable transceivers are of various types and from different vendors, you canperform the following configurations to identify main parameters of the pluggabletransceivers, including transceiver type, connector type, central wavelength of the lasersent, transfer distance and vendor name or vendor name specified.Follow these steps to identify pluggable transceivers:
