SDI optical transceivers are known to many people, initially applied in the radio and television industry. SDI series optical modules include many types, such as SDI SFP optics(mainly includes 3G-SDI Video SFP, 6G-SDI Video SFP, 12G-SDI Video SFP), SDI SFP+ optical module(mainly includes 3G-SDI Video SFP+, 6G-SDI Video SFP+, 12G-SDI Video SFP+), etc. Then today we will talk about types…

Both 4WDM and CWDM4 belong to 100G QSFP28 series optical transceiver and are certainly related to WDM (wavelength division multiplexing)tech. Maybe there are still people confused about what differences between QSFP28 4WDM and QSFP28 CWDM4 optical transceiver are. An Introduction to 100G QSFP28 4WDM Optical Transceiver 4WDM(4-Wavelength Wavelength Division Multiplexing) optical module is defined by 4WDM MSA, targeted for longer…

To satisfy the increasing demands on more-cost-effective and lower-power-consumption 100G optical networks, 100G QSFP28 4WDM optical transceivers emerge in the market. The 100G 4WDM series optical module currently includes three specifications in total: 100G QSFP28 4WDM-10, 100G QSFP28 4WDM-20, 100G QSFP28 4WDM-40. Today, in this article, Gigalight will mainly introduce them to you. Before coming into today’s topic, it will…

On account that DWDM (Dense Wavelength Division Multiplexing) technology can make full use of the huge bandwidth resources of the optical fiber, greatly increasing the transmission capacity of the system and reducing the transmission cost, the technology has been widely used in the large-capacity transmission of long distance network and backbone network. If DWDM technology is introduced into the metropolitan…
