BN623
Electrical to Optical Transceiver for Audio & Control
Description
The BN623 is a compact stand-alone multi-format converter for use with broadcast analogue audio and control signals. Two bi-directional analogue audio signals are provided over 2 fibres. Additional control data and GPI signals are also transmitted over the same pair of fibres. The BN623 is ideally suited to linking audio intercom panels remotely over fibre. The BN623 can be supplied in multimode, singlemode and CWDM variations to suit all applications and is a perfect complement to the BC323, BC550 and BC323-63 modules. Power is provided by a DC source of 4.5 to 17V via a 4 pin XLR or the Bluebell PS12 in-line power adapter.
For versions that fit into the BC Series 19” rack frames please contact the Sales Office.
