FiberBox Plus
Ultimate value pick for 10 Gigabit outdoor networking.
High masts, poles, or towers – your connection will be safe

There are two ways to look at the brand new Fiber Box Plus. On the one hand, it’s a massive upgrade of our previous FiberBox devices. This version features a modern ARM CPU, more RAM, and four 10-Gigabit SFP+ ports. Fast and reliable connectivity on a budget. Without the distance limitations of Ethernet. There’s also a Gigabit Ethernet port for management purposes or PoE-in powering. We’ve also included a 2-pin terminal and a standard DC jack, so you have 3 different power options to choose from. FiberBox Plus supports a wide input voltage range of 24-57V. And it is remarkably efficient: maximum power consumption (without attachments) is only 7W!

CRS305-1G-4S+OUT - MikroTik CRS305 1x GbE + 4x 10G SFP+ FiberBox Plus Managed Outdoor Switch

Another way to look at the new FiberBox Plus – it’s a budget version of the amazing netFiber 9. You can save a lot of money if you don’t need the extra Gigabit SFP ports. It even features the same impressive Marvell 98DX226S switch-chip, so the performance is definitely there! This rugged outdoor switch is perfect for connecting mast devices. Like the mANTBox 52 or the LHG XL 52. Imagine a huge campsite with several guest houses, a food court, and the owner’s cabin. You can connect all the locations with the FiberBox Plus. One of the fiber connections can be used for the mANTBox base station – to provide general connectivity for the guests. Another connection could go to the owner’s house. And the third could be used in the food court – to connect their payment and inventory servers.

Usually, you would need some kind of a junction box to keep everything safe. But our FiberBox Plus comes with a solid water resistance rating of IP66. That means protection against powerful water jets from any direction. So in the campsite scenario, your setup is not only safe from all kinds of crazy weather, but it can also withstand young pranksters with a garden hose. Not to mention damp basements, elevator shafts, seaport infrastructure, and so on. With FiberBox Plus, you have nothing to worry about.
