What I want to share with you today is our easy Tianguang Communication QSFP+ optical module and QSFP28 optical module products. With the rapid development of optical communication in recent years, users' demand for the network has also increased sharply. 100G optical module has become the focus of attention of users in the market.

Users of 100G network usually encounter some problems, for example, the transmission distance of QSFP28 optical module can reach 30km, in order to achieve longer distance data transmission, it is necessary to use 40G QSFP+ optical module on 100G switch.

So many users may wonder, can the QSFP+ optical module be plugged into the QSFP28 port of the 100G switch? Can the QSFP28 optical module be plugged into the QSFP+ port? Yi Tian will give you detailed answers to these two questions.

QSFP28

The outline size of QSFP28 optical module is the same as QSFP optical module, but their transmission mode is different, the former is 4x10G or 4x25G, the latter is 4x10G, so 100G QSFP28 port can use QSFP+ optical module or QSFP28 optical module.

The SFP+ optical module cannot run on the SFP port, and the same QSFP28 optical module cannot be used on the QSFP+ port. The principle of mixed use of optical modules with different rates in switches is basically attributed to the optical fiber and switch ports used, and the ports of the optical modules must match the port shape of the switch. at the same time, the switch port rate should be equal to or greater than the optical module rate used.

The QSFP28 port can use the QSFP+ optical module, but the QSFP28 optical module cannot be used on the QSFP+ port. Remember to configure the switch when using the QSFP optical module on the QSFP28 port. To ensure that network transmission works properly, you need to ensure that both ends are connected to the same connector and that there are no compatibility issues. Yi Tianguang Communication provides the above QSFP+ optical module and QSFP28 optical module, which can meet the needs of all customers!
