QSFP28 Optical Transceiver Is a More Ideal Solution for 100G Optical Network?

Before the advent of the 100GBASE QSFP28 optical transceiver (an optical transceiver that can be used to support 100G transmission), the development direction of the 100G network is 10G → 40G → 100G. After the 100GBASE QSFP28 optical transceiver appears, 10G → 25G → 100G or 10G → 25G → 50G → 100G development model began to spread widely in…

Three Kinds of QSFP28 Optical Transceiver Differences

The appearance of the QSFP28 optical transceiver is the same as that of the 40G QSFP + optical transceiver. The difference is that QSFP28 optical transceiver can transmit optical signals up to 100G. Therefore, QSFP28 optical transceiver has become the mainstream 100G optical transceiver and the preferred solution for network upgrade of 100G. This article describes the differences between the…

Difference between 100G QSFP28 and CFP/CFP2/CFP4 Optical Modules

Before the advent of the 100G QSFP28 optical module (an optical module that can be used to support 100G transmission), the development direction of the 100G network is 10G > 40G >100G. After the QSFP28 optical modules appeared, the development mode of 10G > 25G > 100G or 10G > 25G > 50G >100G began to become widespread in the…

100G Optical Transceivers: How Much Do You Know?

The earliest developed 100G optical module was developed in 2010, which form factor is CFP. At that time, IEEE launched three standards (SR10, LR4 and ER4) for 100G optical modules, separately focusing on the 100m, 10Km and 40Km transmission. Then the IEEE standard added new 100G SR4 project, but in 2013 it did not reach consensus. By 2016, the 100G…
