Spare host adaptor for Multibridge

This Blackmagic Design ADPT-3GBI/OPT module serves as a spare host adaptor for Multibridge Pro and Extreme units. It installs directly into a 4-lane PCI Express slot inside a compatible computer. The adaptor enables the Multibridge hardware to be shared across multiple workstations. It provides a direct connection path for professional video workflows.

Suited for multi-system studios

Editors or facilities that already own a Multibridge Pro or Extreme and need to connect additional computers will find this adaptor necessary. It is not a standalone capture or output device and cannot function without the Multibridge hardware. Buyers without a compatible Multibridge unit should look elsewhere for their I/O needs. The module addresses a specific expansion scenario only.

Consistent link under sustained use

Because the adaptor mounts in a 4-lane PCI Express slot, it maintains a stable electrical connection during long ingest or playout sessions. There are no active components on the module that throttle under thermal load. The optical SFP interface handles continuous 3G-SDI bandwidth without signal degradation. Reliability depends on the host system cooling and the Multibridge unit itself.
