Description

BC501T Single Channel Electrical to Optical Converter Composite – AV + 2 x Audiopdf

The BC501T is a transmitter for the conversion of composite analogue video and two analogue audio channels into fibre optical cable. The incoming video signal is clamped and converted to digital before transmission down a single optical fibre. Two separate audio channels are also filtered and converted to digital before being presented to the optical driver. The card does not rely on a video signal for transmission and can be used as an audio only transmission system. All Bluebell cards are designed to retain maximum integrity of the signal path offering excellent jitter free optical transport.

The BC501 will also pass tri-level syncs, VITS, SIS, teletext data and Timecode. The BC501 can be used with a standard optical splitter to distribute syncs and Timecode optically within a facility.

The BC501T is available in multimode, singlemode, WDM and CWDM variants to suit any fibre application.

The BC501T 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 BC501T can be housed in an individual rugged enclosure.
