The CRS310-1G-5S-4S+IN switch is, in fact, an indoor variation of the prominent netFiber 9 switch, consequently, many small and medium ISPs use it for reliable 10 Gigabit fibre connections stretching over a hundred meters. To elaborate, this is the perfect upgrade for existing CRS212 setups because it features five 1G SFP ports, four 10G SFP+ ports, and an additional Gigabit Ethernet port. Furthermore, you’re getting the modern ARM v7 CPU running at 800 MHz, 256 MB of RAM, and better cooling. Indeed, the new Marvell switch-chips bring phenomenal performance to the table!

Port and Deployment Features

Significantly, the Gigabit Ethernet port has a direct connection to the switch chip; therefore, you can enjoy full gigabit speed there. Moreover, it supports PoE-in, which grants you an additional powering option in tricky spots. Additionally, you can mount this switch in a standard 1U rack to keep everything organized. In this configuration, it offers all the power you would expect from a rackmount device: the CRS310 supports hardware offloaded VLAN-filtering and even some hardware offloaded Layer-3 routing.

Ideal Use Case

Ultimately, the CRS310-1G-5S-4S+IN is a fantastic tool for anyone working with indoor connections over 100 meters while simultaneously keeping data loss and ping low. As an extra benefit, optical fiber can be a great alternative to copper if, for example, you are worried about electromagnetic interference, tampering, or eavesdropping.
