Dual channel, multi-format interfaces


Dual channel, multi-format interfaces for use in  Outside Broadcast (OB) and studio applications, and are able to handle many different formats of broadcast video, audio and data signals. Both units are supplied with four empty SFP carriers, allowing users to fit their own choice of optical or coaxial SFP cartridges to suit particular operational requirements. The interfaces can typically be used to convert signals between optical and electrical formats, for wavelength management (conversion between wavelengths) and signal monitoring. They can also be used for regenerating multimode optical signals as singlemode (or vice-versa) within existing fibre systems. A wide range of signal types is supported, including 12G-SDI, DVI, HDMI, composite video, MADI and Ethernet at various bitrates up to 11.88 Gb/s. The “empty cage” format makes them extremely versatile as their functionality is defined by the user’s choice of SFP cartridges: they can be configured for a different application simply by changing cartridges. Although they can form part of a fixed installation, broadcast engineers will find them a practical “toolkit”, to convert between the many different signal formats now in use.The BC369 is intended for use with transceiver cartridges: internally it comprises two independent, bi-directional signal paths, each of which interconnects a pair of SFP carriers in both directions (Rx to Tx, Tx to Rx). Each SFP has a bicolour LED confirming valid signal input. The BC369D is intended for use with two dual transmitter and two dual receiver cartridges: again two independent signal paths are available, permitting four separate signals to be passed from input to output. Single-channel cartridges may be installed in either module type if only one signal path is required. The cards are part of the Bluebell Opticom BC Series and are compatible with all BC Series racks and enclosures, including the 3RU BC100 (15 cards) and the 1RU BC160 (6 cards): the BC101 and BC102 are also available to accommodate one or two cards respectively. SNMP monitoring is available with the 19” racks when a BM102 network card is fitted.
