HUBbox NV120-R14-R14

The HUBbox 12G NV120-R14-R14 Dual Optical Fiber Converter converts dual Fiber signals to 12G-SDI, with support for 12G-/6G-/3G-/HD-/SD-SDI. Supports data rates from 270Mbps to 11.88Gbps.


Every HUBbox™ 12G unit comes equipped with AutoSFP® functionality, similar to the XFD line. This makes the HUBbox™ 12G extremely flexible. Simply by replacing the SFP, it can easily be changed into a dual transmitter or a transceiver. We’ve also added dual BNCs per channel to the design, giving dual outputs or loop-trough.


It is housed in a compact and rugged aluminum case ideally suited to both studio and portable applications.


The HUBbox 12G is perfect for using with any XFD system where one or two signals are required remotely.
