BLUEOPTICS Compatible MikroTik QSFP28-4SFP28-DAC-2M BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 2 Meter, AWG26

The BLUEOPTICS Q28-4S28-DAC-2M-MT-BL is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for 100 Gigabit Ethernet applications. It converts a single QSFP28 port into four SFP28 ports, enabling cost-effective 100G to 4x25G connectivity in data centers and enterprise networks. Fully compatible with MikroTik equipment and MSA compliant, this cable ensures reliable, low-latency transmission over a 2-meter length.

Advantages

This breakout cable offers a simple, plug-and-play solution for high-speed network interconnects. Its passive design consumes no power, reducing overall energy costs. The AWG26 gauge provides optimal signal integrity for short-reach links, while the robust construction ensures long-term durability. Ideal for top-of-rack to server connections, it simplifies cable management and reduces clutter.
