All electronic components of a transmission system, some of which can be programmed, form the active components of a said system. These include components such as individual diodes for transmission and reception, integrated transceivers, and optical amplifiers.
Next-generation active optical modules meet the requirements of a wide variety of data rate and range requirements with a variety of 850, 1310, and 1550 nm pluggable transceivers and tunable lasers. These include 4/2/1G SFP, 10G XFP, 16/10/8/6G SFP +, 40G QSFP+ and 100G CFP2, CFP4 and QSFP28 modules.
