Optical to Electrical Receiver 3G-SDI, Audio


Optical to Electrical Receiver 3G-SDI, Audio The BC551R is a receiver for the conversion of an optical signal into electrical 3G-SDI, HD-SDI, SD-SDI and ASI. The incoming optical signal is fed to a trans-impedance and limiting amplifier before being electrically reclocked on the output. A reverse path for an audio or control data signal is carried on a second fibre making the BC551 perfect for adding cost effective fibre I/O to compact remote camera systems. The BC551R is available in multimode, singlemode, WDM and CWDM variants to suit any fibre application. The BC551R occupies a single slot in the BC100-3RU 19″ rack-mounting frame which can hold up to 15 single slot cards. This dual functionality allows 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. Alternatively GP-Output alarms can be triggered via the BM100 module. For stand alone applications the BC551R can be housed in an individual rugged enclosure.
