QSFP28 PSM4 vs. QSFP28 SR4 vs.QSFP28 LR4 Optics: What Are the Differences?
Although QSFP28 optical transceiver has the same appearance as 40G QSFP+ transceiver, and QSFP28 optical transceiver module wins out by virtue of its transmission optical signals up to 100G. Now, QSFP28 optical transceiver has developed as the mainstream of 100G optics and also as the first solution for an option to upgrade 100G Ethernet. While the main types of QSFP28…
The Latest QSFP28 Optical Transceivers: QSFP28 4WDM and QSFP28 ER4 Lite
The 100G optical module is with a variety of packaging forms, mainly including the early CFP/CFP2/CFP4 and the new-generation QSFP28. As a hot solution of the 100G network, CFP series and QSFP28 optical transceiver have their own advantages. They all play a role in the specific application of the 100G network. Currently, it seems that QSFP28 series optical transceiver is…
An Overview of 4WDM Optical Transceiver
In current optical communication market, optical transceiver products are developed in the trend of high data transmission rate, longer reaches, lower power consumption, etc. To keep pace with the trend better, many new optical module products with high transmission rate and longer reaches emerge, such as the latest one, QSFP28 4WDM(4-wavelength Wavelength Division Multiplexing) optical transceiver. In this article, we…
