MikroTik CRS310-1G-5S-4S+IN 10G Fiber Switch

Description

The MikroTik CRS310-1G-5S-4S+IN is a high-performance managed fiber switch designed for internet service providers, WISPs, enterprises and network infrastructure projects requiring reliable 1G and 10G fiber connectivity. It combines 5 × 1G SFP ports, 4 × 10G SFP+ ports and 1 × Gigabit Ethernet port in a compact 1U rackmount design.

With its combination of standard SFP and high-speed SFP+ interfaces, the MikroTik CRS310-1G-5S-4S+IN provides a practical platform for upgrading network infrastructure from Gigabit to 10 Gigabit connectivity. It is particularly suitable for fiber-based networks where longer-distance links, high bandwidth and reduced electromagnetic interference are important.

1G and 10G Fiber Connectivity

The CRS310-1G-5S-4S+IN provides five 1G SFP ports for standard Gigabit fiber connections and four 10G SFP+ ports for high-speed uplinks. This combination allows network operators to connect multiple fiber links while maintaining higher-speed connections toward the network core.

The additional Gigabit Ethernet port is directly connected to the switch chip and provides a dedicated Ethernet management and connectivity interface. The port also supports PoE-in, providing an additional powering option where suitable PoE infrastructure is available. MikroTik specifies 18–57V DC input through the DC jack and PoE-in.

Designed for ISP and WISP Networks

The MikroTik CRS310-1G-5S-4S+IN is well suited to ISP and WISP infrastructure where fiber connectivity is required between access, distribution and aggregation points. Its 10G SFP+ interfaces can provide high-speed uplinks to routers, core switches and other aggregation equipment, while the 1G SFP ports can serve standard fiber connections.

For network operators in Kenya and across Africa, fiber switching can be particularly useful when expanding broadband infrastructure, connecting remote network locations or upgrading existing Gigabit networks. The CRS310 provides a compact way to introduce 10G fiber connectivity without requiring a large rackmount platform.

Hardware-Offloaded Switching

The CRS310-1G-5S-4S+IN uses the Marvell 98DX226S switch chip and supports hardware-offloaded VLAN filtering. MikroTik also provides some hardware-offloaded Layer 3 routing capabilities, giving network administrators additional flexibility when designing managed network infrastructure.

The switch supports RouterOS v7 and SwitchOS, allowing it to be used for different network requirements. RouterOS provides advanced networking and routing functionality, while SwitchOS provides a focused management environment for switching applications.

Rackmount Fiber Switch

The CRS310-1G-5S-4S+IN is designed for installation in a standard 1U rackmount environment. Its compact dimensions make it suitable for network cabinets, server rooms, ISP facilities and other structured network infrastructure.

The device also includes an RJ45 serial console for management and recovery. MikroTik specifies 256 MB RAM, a dual-core 800 MHz CPU architecture, 16 MB flash storage and a maximum power consumption of 20W.

MikroTik CRS310 for Kenya and Africa

The MikroTik CRS310-1G-5S-4S+IN is suitable for fiber network deployments in Kenya and across Africa. It can be used by internet service providers, wireless ISPs, telecom operators, enterprises, system integrators and organizations expanding high-speed fiber infrastructure.

Its combination of 1G SFP connectivity, 10G SFP+ uplinks, Gigabit Ethernet, PoE-in and managed switching makes it suitable for network aggregation, fiber distribution and high-speed uplink applications.

Globikom Group supplies MikroTik networking and telecom equipment in Kenya and serves customers across Africa. The CRS310-1G-5S-4S+IN is part of our range of MikroTik switching and networking equipment for ISP, enterprise and telecommunications infrastructure.

The MikroTik CRS310-1G-5S-4S+IN is also suitable for network upgrades where existing Gigabit infrastructure needs a practical path to 10G connectivity. The combination of 1G SFP ports and 10G SFP+ ports allows network operators to connect fiber distribution, aggregation and uplink equipment within the same switch. Its compact 1U rackmount design makes it convenient for server rooms, ISP network cabinets, enterprise IT environments and other professional indoor installations where rack space and reliable fiber connectivity are important.
