Verifying and diagnosing transceiver modules
At present, there are three types of commonly used transceivers, as shown in Table 19. They can be further divided into optical transceivers and electrical transceivers based on transmission medium.
Table 19: Commonly used transceivers
Transceiver type | Application scenarios | Whether can be an optical transceiver | Whether can be an electrical transceiver |
|---|---|---|---|
SFP (Small Form-factor Pluggable) | Generally used for 100M/1000M Ethernet interfaces or POS 155M/622M/2.5G interfaces | Yes | Yes |
SFP+ (Enhanced 8.5 and 10 Gigabit Small Form-factor Pluggable) | Generally used for 10G Ethernet interfaces | Yes | Yes |
XFP (10-Gigabit small Form-factor Pluggable) | Generally used for 10G Ethernet interfaces | Yes | No |
