Product Description
Approved Networks Brocade/Arista 40GBASE QSFP+ Passive DAC Cable (QSFP+ to 4 x SFP+) Multi-Vendor Breakout Length Required
A passive DAC cable carries an Ethernet signal over a short length (typically under five meters) of copper with no additional components to boost the signal. The host networking equipment must support the signal processing functions for a passive DAC to work. When a DAC is inserted, networking gear that is compatible with passive DACs reads the module type so the signal conditioning can be activated. Today, 98% of the market utilizes passive DACs for transmissions of seven meters and under, but this depends on the data rate.
