Electrical to Optical Receiver 3G-SDI, HD-SDI, Control, Audio, Data


Electrical to Optical Receiver 3G-SDI, HD-SDI, Control, Audio, Data The BC561R 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 2 x differential analogue audio signals and a genlock/composite signal is carried on a second fibre making the BC551 perfect for adding cost effective fibre I/O to compact remote camera systems. The BC561R is available in multimode, singlemode, WDM and CWDM variants to suit any fibre application. The BC561R occupies a single slot in the BC100-3RU 19″ rack-mounting frame which can hold up to 15 single slot cards. Signal and card monitoring is achieved through SNMP monitoring in the BM102 network card. For stand alone applications the BC561R can be housed in an individual rugged enclosure.
