All SFP modules must be used in pairs. For common SFPs, we should connect two SFPs with the same wavelength together. For example, we use 850nm SFP at one end, then at the other end we have to use 850nm SFP (as shown in the picture below).
What is the difference between SFP, SFP+, and XFP optical modules
For BiDi SFP, because it uses different wavelengths to transmit and receive signals, (security weak current) we should connect two BiDi SFPs with opposite wavelengths together. For example, we use TX1310/RX1550nm BiDi SFP at one end, then at the other end we should use TX1550/RX1310nm BiDi SFP (as shown in the picture below).
What is the difference between SFP, SFP+, and XFP optical modules
SFP+ optical module advantages
1. SFP+ has a more compact form factor than X2 and XFP packages (the same size as SFP);
2. It can be directly connected with the same type of XFP, X2, XENPAK;
3. The cost is lower than XFP, X2, XENPAK products.
