Direct answer for buyers
The MikroTik CRS504-4XQ-OUT is an outdoor, passively cooled switch with four 100G QSFP28 ports. It is mainly used to aggregate high-bandwidth fibre links at outdoor cabinets, towers, venues, campuses, industrial areas and building-to-building network points. It suits service providers, system integrators and organisations that need 100G or breakout connectivity without placing the switch in a climate-controlled rack. Before proceeding, confirm link speed, fibre type, optical reach, cable-gland compatibility, power source, mounting method, RouterOS configuration and whether each QSFP28 port will operate as 100G, 40G, 4×25G or another supported mode.
What the CRS504-4XQ-OUT does
This device provides a compact switching point for high-speed optical and direct-attach connections. Each QSFP28 port is built around four 25G lanes, allowing a network designer to use a port as a 100G link or, with suitable supported cabling and configuration, break it into multiple 25G connections. It can also form part of mixed-speed designs where compatible modules and settings are used.
The unit runs RouterOS v7 and uses a Marvell Prestera 98DX4310 switch chip. MikroTik identifies support for functions including VLANs, access-control lists, MLAG, jumbo frames and selected Layer 3 hardware offloading. Actual behaviour depends on RouterOS version, topology, configuration and feature combination, so critical designs should be validated before production deployment.
Who should consider it
The CRS504-4XQ-OUT is relevant when the network edge requires very high throughput but the switching point is located outside a standard data-room environment. Typical buyers include internet service providers, campus operators, industrial facilities, event-production teams, CCTV and media-network integrators, data-intensive businesses and contractors building high-capacity links between buildings.
It may be less suitable where many copper access ports, built-in PoE output, large numbers of native SFP+ ports or a conventional rackmount chassis are required. In those cases, a different MikroTik switch or a combination of aggregation and access switches may produce a cleaner design.
Business challenges this outdoor 100G switch can address
Outdoor aggregation point
A protected indoor cabinet may be unavailable near the fibre convergence point. The IP66-rated enclosure gives network planners an option for appropriate outdoor mounting, provided installation instructions, sealing, grounding and local electrical requirements are followed.
Limited fibre count
A single 100G uplink can carry substantial aggregated traffic between distribution points. Breakout support can also let one QSFP28 interface connect several 25G devices, reducing the need for a larger chassis in suitable designs.
Flexible powering
The unit accepts power through a DC jack, two-pin terminal or 802.3bt PoE-in. This gives installers options when a conventional AC outlet is not positioned beside the switch, although power budgets and cable runs must be checked carefully.
Mixed high-speed links
Network upgrades rarely happen in one step. Compatible modules, converters and breakout cables can help integrate 100G, 40G, 25G, 10G or lower-speed links, but every combination should be confirmed against MikroTik compatibility guidance.
Capability band
Four QSFP28 ports support high-capacity backbone and aggregation designs.
Suitable cables can divide a QSFP28 interface into multiple 25G or other supported lanes.
No fan is required, helping reduce moving parts and acoustic concerns at the installation point.
WebFig, WinBox and command-line methods support administration and monitoring.

Compatibility and enclosure protection notice
The outdoor rating depends on correct installation. MikroTik documentation states that the device is intended primarily for optical-fibre applications where cables pass through the cable glands before connection to the QSFP modules. DAC, AOC and breakout cables with non-separable connectors may require a gland to be removed in some positions. When that happens, the enclosure protection can reduce from IP66 to IP54. Buyers should therefore decide on the exact cable and module combination before mounting the switch. For a permanent outdoor deployment, fibre modules and correctly sealed cable entries may be preferable to a design that leaves an enlarged opening.
Compatibility should also be checked at both ends of every link. Confirm supported speeds, FEC requirements, auto-negotiation behaviour, fibre mode, wavelength, connector format, temperature rating and maximum reach. A cable that physically fits is not automatically suitable for the required line rate or environment.
Deployment and purchase journey
Map the traffic
Define current and expected throughput, uplink count, endpoint speeds and redundancy needs.
Select link media
Choose compatible QSFP28 optics, DAC, AOC, breakout cables or converters for each connection.
Plan outdoor installation
Confirm pole or structure mounting, cable sealing, grounding, drainage, access and environmental exposure.
Define power and resilience
Choose DC, terminal or 802.3bt PoE-in and determine whether backup power or redundant paths are required.
Configure and test
Update RouterOS, secure access, create VLANs, apply policies and validate every link under expected load.
High-capacity switching without a large outdoor cabinet
One of the strongest reasons to consider the CRS504-4XQ-OUT is physical efficiency. Four QSFP28 ports can provide up to four 100G interfaces in a compact enclosure. In a design where several 25G devices converge at the same location, breakout cabling can create a larger number of logical interfaces without installing a full-size modular chassis. This can be valuable on rooftops, poles, temporary venues or industrial structures where space, cooling and cabinet depth are constrained.
Port density should still be evaluated realistically. Once a port is reserved for an uplink or redundant path, fewer interfaces remain for connected devices. A four-port switch is effective when the topology is deliberately compact, but it is not a substitute for a high-density aggregation platform. Buyers should draw the intended topology and count both production and future links before deciding. FourTeck can help translate the topology into a bill of materials that includes the switch, optics, breakout cables, patching and power components.
RouterOS management and switching features
RouterOS v7 gives administrators a consistent MikroTik management environment with WebFig, WinBox and command-line access. The platform can be used for VLAN segmentation, link configuration, monitoring, access control and other switching functions. MikroTik also identifies support for MLAG, jumbo frames and selected Layer 3 hardware offloading on this hardware family. These capabilities can make the switch useful in more advanced topologies, but feature support is not the same as unlimited hardware acceleration in every combination.
Before production use, the administrator should verify which functions remain hardware offloaded, how the chosen RouterOS release handles the required protocol, and whether the configuration introduces CPU-bound processing. Firmware should be maintained according to the organisation’s change process. The management service should be restricted to trusted networks, default credentials must be replaced, unnecessary services disabled and configuration backups stored securely. Monitoring should include interface errors, optical levels where supported, temperature, voltage and link-state events.
Powering flexibility for outdoor network points
The CRS504-4XQ-OUT offers three input methods: a DC jack, a two-pin terminal and 802.3bt PoE-in. This is useful when the installation point has limited access to mains power. A compliant high-power PoE source may let power and management connectivity reach the location through an Ethernet run, while the switching traffic uses fibre. Alternatively, a local DC plant or secured power supply can feed the terminal or jack.
Power planning must include the switch and installed optical modules. QSFP28 transceivers can add meaningful consumption and heat, particularly in a sealed outdoor enclosure. Confirm the available wattage, cable loss, voltage at the device, surge protection, grounding and temperature range. Where uptime is important, consider upstream UPS capacity, dual-path network design and practical access for replacement. The presence of several input methods does not automatically create full power redundancy; the complete electrical design determines resilience.
Ideal environments and use cases
Service-provider aggregation
A compact outdoor node can aggregate high-speed access or distribution links before traffic returns to a core location. Routing, redundancy and subscriber-service requirements must be designed separately.
Campus and building links
The switch can sit at a fibre convergence point between buildings where indoor rack space is unavailable. Fibre route protection and lightning-risk planning remain important.
Outdoor events and media
Temporary production networks may require high-bandwidth links for video, storage and control systems. Weather protection, power distribution and rapid recovery procedures should be planned.
Industrial or infrastructure sites
High-speed fibre can connect processing, surveillance or operational systems across large facilities. Environmental, safety and network-segmentation requirements should be reviewed.
High-resolution surveillance backbones
Large camera estates may create substantial aggregate traffic. The CRS504 can form part of the backbone, while access-layer PoE switches serve cameras at the edge.
Edge compute and storage
Where outdoor or semi-outdoor compute nodes exchange large datasets, 25G or 100G links may reduce transfer bottlenecks. Application latency and storage architecture still require separate assessment.
