D-Link DEM-CB300QXS – 3m 40G QSFP+ to QSFP+ Passive Direct Attach Cable for DXS-3600-EM-4QXS
Overview:
• The D-Link DEM-CB300QXS is a 3-meter 40G QSFP+ to QSFP+ Passive Direct Attach Cable designed for high-speed short-distance connectivity.
• It is designed to interconnect switches with 40G interfaces, providing higher data rate and better port density than using standard SFP+ cable solutions.
• The cable supports data transfer rates up to 40Gbps, with low crosstalk and low power consumption, making it suitable for rack-level and data center connections.
• It uses the QSFP+ form factor, which combines four transmit channels and four receive channels in one compact cable design.
• The DEM-CB300QXS helps reduce cost by eliminating the need for separate QSFP+ transceivers in short-distance 40G links.
