DEM-QX Series
40G QSFP+ Transceivers
Features
• Quad Small Form-Pluggable (QSFP+) form factor
• Hot pluggable
• Supports 40G Ethernet
• RoHS compliant
• Multiple Source Agreement (MSA) compliant
• IEEE 802.3ba 40GBASE QSFP+ compliant
D-Link’s 40G QSFP+ Module series are hot-swappable QSFP+ transceivers that plug into
QSFP+ slots on switches and support 40G Ethernet. The D-Link 40GBASE QSFP+ Module Series
transceivers oer customers a wide variety of 40G Ethernet connectivity options for data
centers, enterprise wiring closets, and service provider transport applications.
Quad Small Form-factor Pluggable Plus Format
The transceivers use the Quad Small Form-factor Pluggable Plus format (QSFP+) connectors,
which integrate four transmitting and four receiving channels. QSFP+ supports up to 10.5 Gb/s
per channel for applications such as 40G Ethernet.
Hot Pluggable
All D-Link transceivers are hot pluggable. You can connect a 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.
40G Ethernet speeds
The transceivers all support 40G Ethernet, which results in very fast data transmissions of up
to 40 Gbit/s. This is 40 times faster than Gigabit Ethernet and enables the switch to handle
faster and higher data transmissions, making it very suitable for business needs.
