FAQ
1、Question：What are the advantages of 100G SR4 QSFP28 Optical Transceiver？
Answer：
（1）It is accorded to the standardized applications
（2）It can directly disintegrate one 100G interface into 4 independent 25G interfaces via adopting the 1/4 of MPO/MTP to LC patch cable on the interface of 100G network device. After that, the type of the switch interface can be unified, and the cost can be also reduced.
（3）Its overall price is one of the most cost-effective options at present.
（4）Its interface is the same as that of QSFP-40G-SR4, which makes it easy for the upgrade from 40G to 100G.
2、Question：I edited the firmware and would like the firmware code to reinstall it. Can you please provide it？
Answer：Yes, our technician will follow to help you with that.
