BN623
Features
- The BN623 is specifically designed to link remote panels in an intercom system back to the main central routing position.
- The robust design allows the unit to be deployed in OB or flypack applications.
- Can be supplied in multimode, singlemode, and CWDM variations to suit all applications, offering a perfect complement to the BC323, BC550, and C323-63 modules.
- Power can be supplied direct to the unit from the standard Bluebell PS12 or any readily available DC supply found on-site.
- A complimentary modular BC Series card is also available when a 19” rack-based solution is required.
BN623
Electrical to Optical Transceiver for Audio & Control
Description
Electrical to Optical Transceiver for Audio & Control
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.
For applications requiring serial control data only the BN723 is available.
