We all know that #Optical Modules, as optical devices that complete photoelectric conversion, are indispensable in optical communication networks. In order to meet different application requirements, #Optical modules with different parameters and functions have emerged as the times require.
According to the packaging form of optical modules, there are several common types of optical modules: #SFP, #SFP+, #SFP28, #QSFP+, #QSFP28, and #QSFP-DD.
The #SFP optical module is an upgraded version of GBIC, with a maximum rate of #4.25G. It is mainly composed of lasers and is characterized by small size and hot-swappable.
#SFP+ optical module is an enhanced version of SFP, with a transmission rate of 10Gbps, which can meet the application of 8.5G Fiber Channel and 10G Ethernet.
The transmission rate of the #SFP28 optical module is 25Gbps. Its advantages are low power consumption, high port density, and support for hot plugging.
The #QSFP+ optical module has a transmission rate of 40Gbps, supports MPO fiber optic connectors and LC fiber optic connectors, and is characterized by small size and hot-swappable.
The #QSFP28 optical module adopts four #25Gbit/s channels for parallel transmission, and the transmission rate is 100Gbps, which meets the application of #100G Ethernet.
The rate of #QSFP-DD optical module is #200Gbps and #400Gbps, using 8 25Gbit/s channels and 8 50Gbit/s channels respectively.
Today we focus on #100G QSFP28, #200G QSFP-DD, and #400G QSFP-DD, which have attracted much attention recently.
