The total transmission rate of qsfp28 optical module can reach 103.1gbps. It has the function of low power consumption, small size and high speed. It includes AOC, Sr4, LR4, Er4, cwdm4, psm4 and other series, using LC or MPO optical port. It is mainly used in 100g data center internal network, data center interconnection, metropolitan area network and 5g wireless network application.
Qsfp28 100g provides four channels of high-speed signals, and the data rate range of each channel ranges from 25 Gbps to 40 Gbps, and finally meets the requirements of 100 Gbps Ethernet (4 × 25 Gbps) and 400 g (100 Gbps 4x) Infiniband enhanced data rate (EDR).
Qsfp28 transceivers usually have several standards – 100gbase-sr4100gbase-lr4100gbase-psm4 and 100gbase-cwdm4. Qsfp28-100g-sr4 works on multimode fiber with a distance of 100m. The 100gbase-lr4 qsfp28 supports longer distances of 10 km. Compared with CFP, qsfp28 transceiver is more popular in the 100g market because of its higher plug-in density.

How to use qsfp28 port to transmit 10g / 25g / 40g?
Among the 100g optical modules with different packages, qsfp28 optical module has become the mainstream module with smaller volume, power consumption and price advantages. But there are some questions in practical application, for example, is qsfp28 port compatible with qsfp + port? Can the qsfp + optical module be used on the qsfp28 port? Is it possible to insert the qsfp28 optical module into the qsfp + port?
How to run 40Gbps on qsfp28 port?
If the client device uses 40g, the rate of qsfp28 port should be reduced to 40g, allowing 40g qsfp + optical module to connect.
Hardware equipment
40g qsfp + optical module with MTP / MPO interface, MTP / MPO 12 core optical fiber jumper
40g qsfp + to qsfp + DAC high speed cable
40g qsfp + to qsfp + AOC active optical cable
to configure
The overall dimension of 100g qsfp28 optical module is the same as that of qsfp optical module, 100g qsfp28 optical module can support 4 * 25g and 4 * 10g, 40g qsfp + optical module can support 4 * 10g.
How to run 10Gbps on qsfp28 port?
If the client device uses 10g, the qsfp28 port speed will be reduced to 40g, and it will be split into 4 * 10g mode through 40g qsfp + optical module.
Hardware equipment
40g qsfp + optical module with MTP / MPO interface, 10g SFP + optical module with LC interface, MTP / mpo-lc optical fiber jumper
40g qsfp + to 4 * 10g SFP + DAC high speed cable
40g qsfp + to 4 * 10g SFP + AOC active optical cable
Hardware equipment
100g qsfp28 optical module with MTP / MPO interface, sfp28 25g optical module with LC interface, and MTP / mpo-lc branch jumper
100g qsfp28 to 4 * 25g sfp28 DAC high speed cable
100g qsfp28 to 4 * 25g sfp28 AOC active optical cable
In addition to transmitting 100g, the 100g qsfp28 port on the switch can operate at 40g, 4 * 25g and 4 * 10g.
