SFP (Small Form-factor Pluggables) may the simple understanding be the GBIC promotion edition. The SFP module (the volume compared to GBIC module reduction half, may dispose on the same kneading board are many a time of above port quantity. Because SFP module in function with GBIC basic consistent, therefore, is also called by some switchboard manufacturer miniaturized GBIC (Mini-GBIC).
The SFP module through has placed CDR and the electricity chromatic dispersion compensation outside the module, but even more reduced the size and the power loss.
The SFP transceiver has many kinds of different transmissions and the receive type, the user may for each link choice appropriate transceiver, provides " which (for example multi-mold optical fiber or monomode fiber) can achieve based on the available optical fiber type; Optical property " . The available optics SFP module divides into the following category generally: 850 nanometer wave length /550 meter distance MMF (SX), 1310 nanometer wave length /10 kilometer distance SMF (LX), 1550 nanometer wave length /40 kilometer distance XD, 80 kilometer distance ZX, 120 kilometer distance EX or EZX, as well as DWDM. The SFP transceiver also provides the copper cable connection, enables mainly for the fiber optic communications design main engine equipment also 夠 through the UTP network line cable correspondence. Also existence wavelength division multiplying (CWDM) as well as single optical fiber " Bidirectional " (1310/1490 nanometer wave length upward/downward) SFP.
The commercial SFP transceiver can 夠 provide the speed to achieve 4.25 G bps. 10 Gbps transceiver's several kind of seal form is XFP, as well as seals basic consistent new variety " with SFP; SFP+" .
