MikroTikCRS310-1G-5S-4S+OUT

netFiber 9 - Outdoor Fiber Switch with 1x Gigabit, 5x 1G SFP & 4x 10G SFP+ Ports

The MikroTik CRS310-1G-5S-4S+OUT netFiber 9 is a compact, outdoor-ready fiber aggregation switch, designed for high-throughput distribution in fiber-based networks. Featuring 9 total SFP/SFP+ ports (5x 1G, 4x 10G) and a Gigabit Ethernet port with PoE-in, this rugged switch excels in wireless tower setups, campus links, and ISP edge locations.

Features

Built inside a tough IP66 weatherproof enclosure, the netFiber 9 is engineered for long-term performance in demanding outdoor environments. It uses a dual-core 800 MHz ARM CPU and 256 MB RAM, delivering fast switching with advanced Layer 3 control through RouterOS, or simplified config via SwOS.

Advanced Options

Ideal for fiber-rich outdoor topologies, the switch handles up to 72 Gbps switching capacity, making it a go-to solution for connecting sector antennas, backbone uplinks, or remote PoPs. Its passively cooled design and sealed housing ensure silent, low-maintenance operation, even in extreme weather.

Product Key Features

• • Outdoor-rated switch with 5x 1G SFP and 4x 10G SFP+ cages for fiber-rich environments

  • Includes 1x Gigabit Ethernet port for PoE input and management

  • Rugged IP66 weatherproof enclosure - built for harsh outdoor deployments

  • Dual boot system: RouterOS Level 5 and SwOS support advanced or simple management

  • Fanless passive cooling for silent and durable performance

  • Powered via PoE-in (802.3af/at) or DC jack - flexible power options

Reliability & Performance

With no fans and an IP66-rated housing, the CRS310-1G-5S-4S+OUT is optimized for dust, rain, and wind resistance. The SFP+ cages support 10G uplinks for backhaul links, while PoE input via Gigabit Ethernet enables simple tower or rooftop deployments using a single cable. The unit is preloaded with RouterOS Level 5, supporting VLANs, ACLs, traffic shaping, and static routing.
