SFP Type

sfp transceivers have a variety of different transmission and receiving type, the user can select the appropriate transceiver for each link, to provide the optical performance can be achieved based
on the available fiber type (such as a multimode fiber or single mode fiber). Optical SFP modules available are generally divided into the following categories:
10 km distance of the wavelength of 850 nm / 550 meters distance MMF (SX)
1310 nm wavelength SMF (LX)
1550 nm wavelength / 40 km distance XD
80 miles from ZX
120 km distance from the EX or EZX
DWDM
SFP transceiver also have copper interface, making the host device designed primarily for fiber optic communication can communicate through the UTP network cable. There are also WDM (CWDM) and single fiber bi-directional “(1310/1490 nm wavelength uplink / downlink), SFP. Commercial SFP transceivers can provide a rate of 4.25 G bps. Several packages of 10 Gbps transceivers are XFP, SFP+, the updated version of SFP.
