Active Pluggable Transceivers

An optical fiber transceiver is also called fiber optic transmitter and receiver, the function of the optical module is photoelectric conversion. The transmitter end takes in and converts the electrical signal into light, after the optical fiber transmission in the fiber cable plant, the receiver end again converts the light signal into electrical signal. Both the receiver and the transmitter ends have their own circuitry and can handle transmissions in both directions.  According to the package, common type of fiber optic transceivers popular in the market is CFP, QSFP, SFP, SFP+, CSFP, XFP. According to the fiber type it connect to, there are MMF (multimode fiber), SMF (Single-mode fiber), as well as WDM fiber (CWDM, DWDM modules).
