The Blackmagic Design BMD-ADPT-6GBI/OPT Adapter is a professional, hot-pluggable SFP (Small Form-factor Pluggable) optical transceiver module designed to convert electrical SDI signals to optical signals for long-distance transmission over fiber optic cable. It is specifically engineered to be inserted into the SFP slots found on various Blackmagic Design products, such as the Teranex Mini converters, HyperDeck Studio recorders, and specific models of the VideoHub router series. This module enables a seamless transition from copper-based SDI infrastructure to a fiber optic network, which is essential for broadcast facilities, live event production, and installations where signals need to travel beyond the 100-meter limit of coaxial cable without signal degradation.

The module operates bi-directionally, meaning a single module can either transmit (convert electrical SDI to optical) or receive (convert optical back to electrical SDI), depending on its configuration and the device it's installed in. It supports the 6G-SDI standard, allowing it to handle video signals up to 1080p60 or 4Kp30, ensuring compatibility with high-definition and early 4K workflows. The use of single-mode fiber provides the capability for transmission distances of several kilometers, far exceeding the reach of copper, while also offering complete immunity to electromagnetic interference, ground loops, and voltage spikes—critical factors for maintaining signal integrity in complex production environments.

As a plug-and-play component, the adapter requires no external power or configuration; it draws power directly from the host device's SFP cage. Its compact, standardized SFP form factor makes it a versatile and interchangeable solution for upgrading existing Blackmagic equipment to support fiber connectivity. By deploying a pair of these modules—one at the source and one at the destination—users can create a robust, high-bandwidth fiber link, extending the flexibility and reliability of their video production and distribution systems.
