Yes, QSFP28 supports both 40G and 100G Ethernet connections.In the data center, various types of optic module transceiver are seen everywhere, such as SFP, SFP+, XFP, SFP28, QSFP/QSFP+, CFP and QSFP28. However, for those who get in touch with them for the first time, just like me, maybe most information, is unfamiliar to them. Fortunately, I have right collected some materials about them some time

There are several different types of 40G QSFP (Quad Small Form-factor Pluggable) transceivers, including:1. 40GBASE-SR4: This transceiver uses multimode fiber (MMF) and has a reach of up to 100 meters.2. 40GBASE-LR4: This transceiver uses single-mode fiber (SMF) and has a reach of up to 10 kilometers.3. 40GBASE-LR4L: This transceiver also uses single-mode fiber (SMF) but has a longer reach of up t

Yes, QSFP (Quad Small Form-factor Pluggable) and QSFP28 are compatible. QSFP28 is backward compatible with QSFP, so a QSFP28 transceiver can be used in a QSFP port. However, it's important to note that the speed and capabilities of the transceiver will be limited to the specifications of the QSFP port.

A QSFP-DD 400G LR4 optical transceiver is a high-speed, high-density transceiver module that supports data transmission at a rate of 400 Gigabits per second (Gbps). "QSFP-DD" stands for Quad Small Form-factor Pluggable Double Density, which refers to the form factor and interface of the transceiver. "400G LR4" indicates that the transceiver uses four channels to transmit data o
