Your most affordable, compact, energy-efficient doorway to the world of 100 Gigabit networking with the CRS504-4XQ-IN from MikroTik.

The next step in upgrading existing 10 or 25 Gigabit networks.

Our 100 Gigabit family keeps expanding – you’ve already seen the incredible CCR2216 100 Gigabit router.

Now it’s time for a matching switch – the CRS504-4XQ-IN. The small size combined with the low power consumption (25W without attachments!) is perfect to start expanding 100 Gigabit networking in everyday setups.

This speed is no longer limited to data centers, ISPs, and large offices. You too can upgrade your 10 or 25 Gigabit network and join the one hundred club!


Use the four 100 Gigabit QSFP28 ports to connect other 100 Gigabit devices or grab a breakout cable to connect multiple 25 Gigabit devices: each port is connected to four 25 Gigabit lines, allowing you to connect 16 x 25 Gigabit devices.

In fact, you can mix and match all kinds of connections this way: 100 Gigabits on one port, 40 Gigabits on the other, 4×25 Gigabits on the third, and maybe even some 10G or 1G cables on the fourth.

Obviously, there is an Ethernet port for management purposes as well.




User Case: Research-Network

This switch is used for quite some time now in the Genomics Data Network project.

A high-capacity data network for our local scientists working on ground-breaking cancer treatments.

Genome data can take up a lot of space, so you need exceptionally fast connections there.

Also, with these devices, Latvia became the first Baltic country to establish a 100 Gigabit connection to the pan-European research network.
