BN623

Electrical <> Optical Transceiver for Audio & Control

The BN623 is designed to connect remote intercom panels back to a central routing position, providing bidirectional analogue audio and serial control data over fibre. Its robust construction makes it ideal for OB and flypack applications, with variants available in multimode, singlemode, and CWDM to suit different system requirements. The unit can be powered using a Bluebell PS12 or standard on-site DC supply, and a complementary BC Series card is available for 19″ rack-based installations, ensuring seamless integration with existing systems.

  • 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 BC323-63 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.
  • The BN623 provides bidirectional analogue audio and serial control data over fibre.
