Single Channel Electrical to Optical Transmitter 12G-SDI, 6G-SDI, 3G-SDI


BlueNanologo Single Channel Electrical to Optical Transmitter 12G-SDI, 6G-SDI, 3G-SDI The BN365T is a transmitter module for the conversion of 12G-SDI signals into fibre optical cable. The incoming signal is auto-sensed and then equalised prior to conversion and transmission down a single optical fibre. All Bluebell products are designed to retain maximum integrity of the signal path offering excellent jitter free optical transport. A loop out is provided for signal monitoring or distribution. Each BN365 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 PS12 unit. The PS12 has an IEC mains inlet allowing easy adoption into standard equipment bays. The BN365 has a 4 pin XLR allowing power from a variety of external DC sources in the range 4.5 to 17 V.The BN365s 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 12G-SDI signals.
