It is a standard which define a type of connector for use in the connection between the camera and the CCU for Broadcasting and high definition professional video combining electrical and optical signals (copper and fiber).<\/p>\n
The SMPTE 304 connector is made to be used with a cable under the SMPTE standard also, in this case, SMPTE 311 standard. This cable consists of:<\/p>\n
2 Single-mode fibers (see Single-Mode Fibre):
\n9.5 \u00b5m\/125 \u00b5m
\nWavelength 1250-1625 nm.
\n\u22640.8 dB\/Km
\n2, 4 or 8 Power conductors (Auxiliary Conductors according to standard):
\nVoltage: 600 Vac
\nCurrent: 10 A
\nSection: 0.6 mm2
\n2 Low Voltage conductors (control or signal) (Signal Conductors according to standard):
\nVoltage: de 42 Vac a 60 Vac
\nCurrent: 1 A
\nSection: 0.22 mm2
\nWhat signals are transmitted?<\/p>\n
This hybrid cable transmits video, audio and control (signal between the camera and its CCU) delivering power signal also.<\/p>\n
What are the benefits?<\/p>\n
The main advantage is that it allows higher lengths compare to triaxial cable or coaxial cable without increasing weight and flexibility. The central strength member gives the needed durability for a continuous use.<\/p>\n
Where is it used?<\/p>\n
This connectivity solution is suitable for transmission in arenas, stadiums or sport events and big installations where long cable runs is required.<\/p>\n
