Generally, 100G QSFP28 has the characteristics of high density and low power consumption. It can not only meet the current network needs but also prepare for future network expansion. It is an ideal optical module scheme for large. Generally, 100G QSFP28 has the characteristics of high density and low power consumption. It can not only meet the current network needs but also prepare for future network expansion. It is an ideal optical module scheme for large data centers. Fiber Mall provides various high-performance 100G QSFP28 optical modules. All modules are strictly tested. The 100G QSFP28 optical module is suitable for 100G Ethernet, EDR Infiniband and 32G fibre channel. Generally, its size and panel density are the same as 40G QSFP+. The 40G QSFP+ uses four 10Gbps channels, and the 100G QSFP28 module is similar. Four high-speed differential signal channels are adopted, and the data rate supports 25Gbps, up to 40Gbps. After understanding the basic concept of 100G QSFP28, this section will explain in detail the differences of 100G QSFP28 transceiver in terms of standard, laser type, transmission medium and distance.After introducing different types of 100G QSFP28 modules, I believe you have a basic understanding of these modules. Next, let's talk about how to select 100G QSFP28 transceiver. · When the transmission distance is 5m-100m, it is recommended to select the QSFP28 SR4 optical module. The transmission distance of such modules is 70m on OM3 optical fib.
