SMPTE 311M, single-mode fibre optic and copper hybrid camera cable, manufactured using Furukawa 2SM-9.2-37.5 ARIB specification cable, terminated with Lemo SMPTE 304M connectors including sleeves, dust caps and gaiters, for high definition video camera to CCU interconnect.
Lemo's range of high performance fibre optics camera connectors have been developed to meet the needs of the new generation of digital TV cameras forming the basis of the SMPTE, ARIB and EBU standards. The LEMO 3K.93C connector has been fully tested, is TUV approved and is used in international events transmissions and in applications such as the Sony BVP9500 super slow motion camera to CCU. The face of each F2 fibre contact in the connector goes through a precise, multi-stage, laboratory standard polishing process. This process achieves excellent optical clarity and alignment, thereby reducing return loss and minimizing insertion loss.
Furukawa's 2SM-9.2-37.5 cable is manufactured to the Japan based ARIB (Association of Radio Industries and Businesses) standard and differs slightly from the SMPTE-311M specification in two respects.
1. The colour code of the control lines is Red and Green (ARIB) instead of Red and Grey (SMPTE).
2. The central strain member is 1.8mm nominal O/D (ARIB) instead of 1.6mm nominal O/D (SMPTE)
However, these differences are internal to the cable, which means that Bryant camera cable assemblies manufactured using the Furukawa ARIB spec cable are fully compatible to both ARIB and SMPTE-311M standards.
In Bryant Unlimited's experience, the construction of the Furukawa ARIB optical hybrid cable ensures a very high resistance against flexure and twists and imparts a smoothness and inherent ability to overcome 'stiction'. This enables it to better withstand the rigours of cable installation on Studio floor or in Outside Broadcast field use and we recommend it for all such applications.
Bryant can not only manufacture but also rebuild most makes of SMPTE camera cables in their Croydon, UK premises; thus avoiding the costs of sending imported cables back to the USA or Asia for repair.
