The BC372, BC372T and BC372R plug in cards are part of the Bluebell Opticom BC Series range of modular fibre interfaces, designed for use across a wide range of broadcast, live production, AV and professional media applications, including Outside Broadcast, studios, venues and fixed installations.
The cards have been designed for the transport of 4K SDI video over a fibre-optic link: typically, they will be used to connect video cameras installed at remote locations, as may be the case at large-scale sporting events, music festivals and similar OB situations. They are compatible with SD, HD, 3G, 6G and 12G SDI video standards: alternatively, they can be used for the transport of MADI data.
The BC372 range comprises three variants:
BC372T transmitter – four independent channels, quad SDI inputs to quad fibre outputs
BC372R receiver – four independent channels, quad fibre inputs to quad SDI outputs
BC372 – four independent channels, direction configurable via on-board switches
The three variants are of similar construction, and in outward appearance differ only in the silk-screened labelling on the faceplate.
Cards will normally be used in pairs, typically with a BC372T installed at the remote end (camera station) and a BC372R at the control centre end (base station). If bidirectional operation is needed, a BC372 may be installed at both locations.
On all variants, the “copper” connections for SDI video use 12G-compliant 75-ohm BNC sockets, while the fibre optic connectivity is quad LC optical connector in two standard SFP carriers.
Single-mode fibre operation will normally be at 1310 nm; alternative CWDM grid wavelengths are also possible. The optical option is generally specified at the time of order. The optical receiver will be wideband.
The module is compact and designed for efficient rack mounting. It occupies a single slot in the BC100/BC100i (3RU) 19″ rack-mount frame, which can hold up to 15 single-slot cards, or the BC160/BC160i (1RU) 19″ frame, which accommodates up to six cards. Enhanced reporting is available via SNMP if a BM102/BM102i network card is fitted to the rack. The rack provides all necessary DC power.
For standalone applications, the BC372 cards can be housed in rugged individual enclosures. Alternatively, BN324 from the BlueNano range can also be used as a throw-down unit for outside broadcast
