The MikroTik CRS504-4XQ-OUT is a high-performance outdoor 100 Gigabit Ethernet switch designed for ISP networks, fiber deployments, and outdoor high-speed connectivity. Featuring 4x 100G QSFP28 ports and a rugged IP66 weatherproof enclosure, it delivers reliable ultra-fast switching in environments where traditional indoor switches cannot operate.

This compact and energy-efficient switch provides flexible connectivity options for outdoor network infrastructure, allowing operators to connect 100G devices or break out each QSFP28 port into multiple 25G connections using breakout cables.

Should high-quality 100 Gigabit connectivity be limited to indoors only? Definitely not! That’s why MikroTik created the CRS504-4XQ-OUT: a versatile, cost-effective, ultra-fast weatherproof switch for all your outdoor needs.

At the core of this masterpiece, we have an incredible Marvell Prestera switch chip. And there are four 100 Gigabit QSFP28 ports. Use them to connect other 100 Gigabit devices or grab a breakout cable to connect multiple 25 Gigabit devices. Here’s where the speedy switch chip really shines: each port is connected to four 25 Gigabit lines. That means you’re getting up to 16 high-speed fiber interfaces from a single outdoor switch! You can mix and match all kinds of connections this way: 100 Gigabits on one port, 40 Gigabits on the other, 4x25 Gigabits on the third, and maybe even some 10G or 1G cables on the fourth. And all this versatility comes in a sturdy, weatherproof IP66-rated enclosure. This rating proves it’s strong enough to handle powerful water jets from any direction!

When it comes to outdoor event planning, you can never be too prepared. So having multiple powering options is a must! And CRS504-4XQ-OUT has got you covered: there’s a standard DC jack, a 2-pin terminal, and 802.3bt PoE-in. We’ve also kept the good old management and console ports – to help you deal with any unexpected situations.

Performance-wise, the MikroTik CRS504-4XQ-OUT is a real workhorse that can handle VLANs, ACL, MLAG, Jumbo frames, and so much more – even some L3 hardware offloading! The mighty Marvell Prestera switch chip dominates most tasks without blowing the power consumption up – only up to 25W (without attachments).

Typical deployments include:

• Outdoor ISP fiber networks
• Tower networking infrastructure
• Stadium and event connectivity
• Campus fiber backbones
• Industrial outdoor networking
