Passive 40G QSFP + cable for direct connection to a length of 3 meters
Nereden Alınır


Passive twinax 40G QSFP + cable is an economical solution to support 40 Gbit / s, to provide a connection with high bandwidth.Passive twinax 40G QSFP + cable is designed to interconnect the switches with 40G interface, while providing higher data rates than with standard SFP +. This series includes two models of cable: DEM-CB300QXS (3 meters) and DEM-CB100QXS-4XS QSFP + connector and four connectors SFP + (1 meter). Cable DEM-CB100QXS-4XS allows you to connect up to four servers with 10G ports. Passive twinax 40G QSFP + cable certified and is compatible with D-Link products to ensure the best performance and reliability.
The ideal solution for high-performance systems
This 40G QSFP + cable supports data transfer rates up to 40 Gbit / s, and provides extremely low crosstalk and power consumption compared with other types of cables. Therefore, this cable is the perfect solution, providing high bandwidth over short distances, making it ideal for use, such as a rack or between racks within the data center.
Format Quad Small Form-factor Pluggable Plus
Passive twinax 40G QSFP + cable D-Link uses the format Quad Small Form-factor Pluggable Plus (QSFP +), which unites four transmit channels and four host channel. QSFP + cable can replace four standard cable SFP +, allowing you to achieve a high-density, efficiency and reduced energy consumption compared to the standard SFP + cable.
Considered 40G QSFP + cable D-Link is equipped with both sides of the connector QSFP +, thus eliminating the need for costly transceivers QSFP +.
