Bluebell BC323R Dual Fibre Optic Receiver -
Schematic Diagram
The BC323R is a Receiver for the conversion of two independent optical signals 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 outputs. Each BC323 Receiver is housed in a compact robust enclosure and is designed for outside broadcast and special events as well as studios. Power is provided via the PS12 unit supplied separately. The PS12 has an IEC mains inlet allowing easy adoption into standard equipment bays. The BC323 Receiver has a 4 pin XLR allowing power from a variety of external DC sources in the range 4.5 to 17 V. The BC323's are extremely compact dual channel fibre optic converters that are perfectly suited to provide interference free transmission and for extending the range of electrical signals, particularly HD-SDI and 3G-SDI signals. Each channel can operate in non-reclocking mode and handles data rates from 50 Mb/s to 3 Gb/s. The BC323 Receiver is available in singlemode, WDM and CWDM variants to suit any fibre application. The BC323 Receiver can also be used to interface to any of the standard Bluebell cards and enclosures.
