BC625
4 Channel Balanced Analogue Audio Transceiver
Description
4 Channel Balanced Analogue Audio Transceiver The BC625 provides bidirectional transmission of multiple channels of analogue line level audio over optical fibre. All inputs are buffered then converted using full 24 bit A/D conversion then multiplexed onto a single optical data stream. The BC625 is particularly suited for multichannel audio transport and applications that require the audio to be carried independently to video or embedded audio signals. All Bluebell cards are designed to retain maximum integrity of the signal path offering excellent jitter free optical transport. The BC625 is available in multimode, singlemode, WDM and CWDM variants to suit any fibre application. The BC625 occupies a single slot in the BC100-3RU 19″ rack-mounting frame which can hold up to 15 single slot cards. Some BC Series processing cards have dual functionality allowing up to 30 channels of video to be transmitted or received from a single 3RU frame. Signal and card monitoring is achieved through SNMP monitoring in the BM102 network card. For stand alone applications the BC625 can be housed in an individual rugged enclosure.
