Transceiver Support Matrix

The Cisco Nexus 6004 switch also supports the following QSFP transceivers:
Note For in-rack or adjacent-rack cabling, the Cisco Nexus 6004 platform supports QSFP+ direct-attach 40
Gigabit Ethernet copper cables, an innovative solution that integrates transceivers with Twinax cables
into an energy-efficient, low-cost, and low-latency solution. QSFP+ direct-attach 40 Gigabit Ethernet
Twinax copper cables use only 1.5 watts (W) of power per transceiver and introduce less than 0.1
microsecond of latency per link. For longer cable runs, the Cisco Nexus 6004 platform supports
multimode, short-reach optical QSFP transceivers. These optical transceivers use approximately 1.5W
per transceiver and have a latency of less than 0.1 microsecond.
