With over 20,000 of these connectors in use the LEMO 3K.93C connector system has proven itself in many different applications from studio and stadium installations to regular OB van use. The system has increasingly been used at all major Olympic events starting with Atlanta in 1996 and the Nagano winter Olympics in 1998, right through to the recent winter Olympics in Turin. In1996 one of the earliest installations was at The Portland Trailblazers Arena, and other installations since include Madison Square Gardens, the Royal Opera House and most of the football arenas in Germany for the 2006 World cup.
Manufactured in stainless steel, the 3K.93C connector incorporates the highly reliable LEMO push-pull latching system and is suitable for up to 20,000 mating cycles and above. With proper termination the fibre contact is also suitable for this level of endurance. The use of fibre optics means that transmission can be made over much longer distances using digital signals from the camera to the base station and at a much higher level of definition. However, the performance of the interconnection is critical if this benefit is to be fully exploited.
The LEMO HDTV Camera connectors use the F2 type Fibre Optic contact. This contact employs ceramic technology in order to achieve optical performance of the highest standard. Simple and fast polishing ensures physical contact of the fibre endfaces, and the same basic contact is used in all of the connector models.
