Structure and Principle of 40G Optical Module
QSFP is the abbreviation of Quad (4-channel) small form-factor pluggable transceiver, which is widely used in 40G Ethernet data transmission, it is a compact, hot-swappable transceiver. The internal transmission channel structure of QSFP+ is composed of 4 independent channels. It is undeniable that 40 Gbit/s optical modules, such as 40G QSFP+ SR4, LR4, PSM4, ER4, etc. will play an important role in high-speed and high-capacity data transmission and have huge market prospects. QSFP+ modules provide an alternative by allowing a compact, high-performance 40G link that is easier to integrate and provides a higher level of operational simplicity. They are typically deployed in metro networks, inter-campus backbones, and data center interconnect (DCI) scenarios that require up to 80km.
