Know before you buy
This cable is designed to bridge high-speed 40G QSFP+ ports on switches or routers to four individual 10G SFP+ ports on servers or other networking equipment. It effectively splits a single 40G link into four separate 10G data streams.
Yes. The plenum (CMP) rating indicates that the cable jacket is made of fire-retardant materials designed to produce minimal smoke and prevent fire spread, making it compliant for installation in building air ducts and plenum spaces.
This cable is built to generic QSFP+ MSA standards, meaning it is designed to be compatible with most major networking equipment manufacturers. However, it is always recommended to verify your switch's port compatibility requirements before installation.
AOC technology uses fiber optics to transmit data, which allows for a much lighter, thinner, and more flexible cable compared to copper. This makes it easier to manage in high-density racks and provides better signal integrity over the 20-meter distance.
In most cases, you will need to configure the 40G port on your switch to 'breakout mode' or 'split mode' via the command-line interface to recognize the four individual 10G channels. Consult your switch's documentation to ensure your hardware supports this configuration.
