Quad Small Form-Factor Pluggable 28 format The transceivers use the Quad Small Form-factor Pluggable 28 format (QSFP28) connectors, which integrate four independent transmitting and receiving channels. QSFP28 supports up to 25 Gb/s per channel for applications such as 100G Ethernet.
Hot-pluggable You can connect the transceiver while the system is powered on without causing any issues, and easily swap one for another without having to reboot the switch each time. This permits modules to be added or removed without interrupting the network, facilitating maintenance and greatly reducing downtime.
100G Ethernet speeds Supports 100G Ethernet, which results in very fast data transmissions of up to 100 Gb/s. This is 100 times faster than Gigabit Ethernet and enables the switch to handle faster and higher data transmissions, making it very suitable for business needs.
D-Link's 100G QSFP28 module is a hot-swappable QSFP28 transceiver that plugs into QSFP28 slots on switches and supports 100G Ethernet.
