Optical to Electrical Receiver 3G-SDI, HD-SDI, SD-SDI, ASI


BlueNanologo Optical to Electrical Receiver 3G-SDI, HD-SDI, SD-SDI, ASI The BC313R 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. Each BC313R 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 optional PS10/XLR unit The PS10/XLR has an IEC mains inlet allowing easy adoption into standard equipment bays. The BC313R has a 4 pin XLR allowing power from a variety of external DC sources in the range 4.5 to 17 V. The BC313s are extremely compact single 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 BC313R is available in singlemode, WDM and CWDM variants to suit any fibre application. The BC313R can also be used to interface to any of the standard Bluebell cards and enclosures. The single channel BC313 receiver is also available with dual outputs. See separate datasheet for full technical information.
