Types of Original Optical Modules
There are various types of optical modules, including SFP (Small Form-factor Pluggable), SFP+, QSFP (Quad Small Form-factor Pluggable), and CFP (C Form-factor Pluggable). Each type supports different data rates and distances, catering to diverse networking needs. Optical modules typically have an electrical interface on the side that connects to the inside of the system and an optical interface on the side that connects to the outside. The optical module, known as Optical Transceiver in English, is a general term for various module categories, including optical receiver modules, optical transmitter modules, optical transceiver modules, and optical forwarding modules. Its primary function entails converting electrical signals into optical signals.
