Get Started


The BG-3GS14 is a 1x4 3G-SDI splitter that splits one SDI input to four SDI outputs simultaneously. With a signal relocking feature it can also extend a video signal for long distance transmission. This reliable and powerful tool provides consistent connections in a variety of different scenarios, like adding a multiple outputs for monitoring a video feed on different displays, splitting the signal and cascading to multiple displays, or extending an SDI signal.

Connectivity and Features

The BG-3GS14 supports a maximum resolution of 1080p@60Hz with 3G-SDI signal. The device also supports a wide range of data rates from 270 Mbps at the low end to a maximum bandwidth of 2.97 Gbps. There is also support for multiple deep color settings such as 8 bit, 10 bit, and 12 bit.

This splitter can also maintain SD signals for up to 200m (656ft), HD signals 120m (393ft), and 3G up to 80m (262ft). Multiple video resolutions are also available with this unit, including SD 480i, 576i and 625i, HD 720p@24/25/30/50/60, 1080i@50/60, 1080p@24/25/30, and 3G 1080p@50/60. It further supports multiple color spaces, including RGB or YCbCr 4:4:4 sampled , YCbCr 4:2:2 or 4:2:0 sampled.

Quality SDI connectors provide reliability due to their interlocking design. This prevents SDI cables from being dislodged from the unit via accidental forces or from loose connections.

The signal ranges provided by the BG-3GS14 allow users to transmit video signals of varying resolutions (SD, HD, and 3G) over different maximum cable lengths. This flexibility is valuable in professional video production and broadcasting environments where maintaining signal quality and ensuring reliable transmission over long distances are critical requirements. Users can select the appropriate mode based on their specific needs and the distance between the source and destination devices.
