Key Features
Use One Supported Port for Four Connections
The four SFP+ tails provide separate 10G channels from a suitable QSFP+ interface. This is useful when compatible high-density equipment needs connections to several 10G endpoints rather than a single 40G peer.
Choose a Verified Host
The listed hosts are DQS-5000-32S, DXS-5000-54S, DXS-3600-16S and DXS-3600-32S. The DXS-3600 hosts require the DXS-3600-EM-4QXS module. Hardware and firmware support for breakout must be confirmed before installation.
Keep the Cable Plan Clear
The one-metre assembly is intended for nearby equipment. Check that all four tails can reach their intended ports without strain and respect the specified 23.5 mm minimum bend radius.
Configure the Ports Before Connecting
Breakout operation depends on the switch configuration and supported endpoint interfaces. The assembly does not independently convert an unsupported 40G port into four working links.

Specs
D-Link DEM-CB100QXS-4XS 40G QSFP+ to SFP+ Breakout Cable
The DEM-CB100QXS-4XS is a passive direct attach copper breakout cable joining one QSFP+ interface to four SFP+ connections. Its one-metre assembly supports four 10 Gbps channels when the source port provides the required breakout function. D-Link lists specific compatible DQS and DXS hosts; the DXS-3600 hosts also require an expansion module. Verify hardware, firmware and port mode at both ends, and plan the short cable route before ordering.
