MikroTik Q+BC0003-S+ – QSFP+ Breakout Patch Cord for SMB & Enterprise Networks

MikroTik Q+BC0003-S+ is a 40G breakout cable with an integrated QSFP+ module at one end and four SFP+ modules at the other, designed to connect a single QSFP+ 40G port to four independent 10G SFP+ devices. It is the direct solution for integrating switches with QSFP+ ports into existing 10G infrastructure without replacing or upgrading the entire network setup.

The cable splits a single QSFP+ 40G port into four independent SFP+ 10G connections — each with dedicated 10 Gbps bandwidth — through a passive plug-and-play connection requiring no additional configuration. The 3-meter length covers typical distances between adjacent racks or equipment within the same communications enclosure. Integrated QSFP+ and SFP+ modules at both ends eliminate the need for separate transceivers, reducing installation cost and complexity.

Q+BC0003-S+ connects directly into the QSFP+ port of CRS326-24S+2Q+RM switches or other MikroTik equipment with QSFP+ ports, simultaneously distributing traffic to four existing 10G SFP+ devices in the infrastructure. The tested operating range of 0°C to +70°C covers standard conditions in any server room or communications rack.

Recommended for integrating QSFP+ 40G switches into networks with existing SFP+ 10G equipment, connecting a central node to four aggregation or storage devices simultaneously, small and medium datacenter infrastructure where full equipment replacement is not justified, and any scenario where a QSFP+ port needs to be distributed across four independent 10G connections via direct cable.
