Mikrotik CRS310-1G-5S-4S+OUT Router 5Ghz 1200Mbps White

The CRS310-1G-5S-4S+IN is an indoor variant of the notable netFiber 9 switch, used by many small and medium-sized internet service providers to provide reliable 10 gigabit fiber connections that extend over 100 meters. With five 1G SFP ports, four 10G SFP+ ports, and an additional Gigabit Ethernet port, it is an ideal upgrade to existing CRS212 setups. You get a modern ARM v7 central processor, 256 MB of RAM, and improved cooling. The new Marvell switch chipset provides phenomenal performance!
The Gigabit Ethernet port has a direct connection to the switch chipset, allowing you to enjoy full gigabit speeds. And it supports PoE-in, giving you additional power options in complex locations.
You can mount this switch in a standard 1U rack to keep everything organized. And it has all the power you expect from a rackmount device: the CRS310 supports hardware-based VLAN filtering. It even has some hardware-accelerated Layer-3 routing.
The CRS310-1G-5S-4S+IN is a fantastic tool for anyone working with indoor connections over 100 meters, while maintaining low data loss and ping. Optical fiber can be a great alternative to copper if you're concerned about electromagnetic interference, tampering, or eavesdropping.
