BC323T Dual Electrical to Optical Transmitter 3G-SDI, HD-SDI, SD-SDI,ASIpdf

The BC323T is a transmitter module for the conversion of two independent 3G-SDI, HD-SDI, SD-SDI and ASI signals into fibre optical cable. Each incoming signal is auto-sensed and then equalised and reclocked prior to conversion and transmission down a separate single optical fibre.

Each BC323T 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 BC323T has a 4 pin XLR allowing power from a variety of external DC sources in the range 4.5 to 17 V.

The BC323s 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 BC323T is available in singlemode, WDM and CWDM variants to suit any fibre application.
The BC323T can also be used to interface to any of the standard Bluebell cards and enclosures.
