Bluebell BN324 Fibre Optic Interface -
Schematic Diagram 1 -
Schematic Diagram 2
The BN324 Series is a range of compact, stand-alone fibre interfaces, which are primarily intended for video OB applications up to 4K format. They allow SDI video signals meeting SD, HD, 3G, 6G or 12G standards to be transmitted over fibre-optic cable.
There are four variants comprising the range:
BN324T transmitter – two independent channels, dual SDI inputs to dual fibre outputs
BN324R receiver – two independent channels, dual fibre inputs to dual SDI outputs
BN324TR transceiver – two independent channels: channel A is configured as a transmitter, and channel B as a receiver
BN324A “adaptive” variant – may be supplied with an SFP module of the customer’s choice, or with an empty SFP cage. It allows users to fit SFP modules of their own choice to suit different applications. Depending on the type of SFP module, the BN324A will automatically configure itself as a dual transmitter, a dual receiver, or a transceiver.
