These industry standard, hybrid fibre, HD camera cables use Lemo SMPTE304 connectors and Furukawa SMPTE or ARIB standard cable. They are assembled to order by Canford, usually on short lead times. The cables, which are generically referred to as SMPTE311M, incorporate two singlemode fibres, two power conductors and two low-voltage conductors, laid up around a stainless-steel strength member, with a copper braid plus a rugged, abrasion-resistant jacket.
The Lemo 3K.93C stainless steel connectors incorporate the highly-reliable Lemo push-pull latching system and are suitable for up to 20,000 mating cycles. With correct care and cleaning, the fibre contacts are also suitable for this level of endurance.
This version of the cable is designed for studio floor applications, and has a 16mm diameter overmoulded jacket. There are two primary specifications for this type of cable, SMPTE311 and ARIB, however the 16mm type is only available in the ARIB version '2SM-16-37.5' (also known as 'J grade'). For detailed specifications see Furukawa SMPTE311 Fibre HDTV Camera Cables.
Cables are also available with the standard 9.2mm Furukawa cable and with the lightweight 6.8mm type. Cables are also available with the standard 9.2mm Furukawa cable and with the 'studio floor' 16mm type. See Furukawa camera cable assemblies.
Panel-mount connectors with break-out tails for patching or splicing, are also available. See Canford SMPTE311M Hybrid Fibre Camera Cable Breakout Assemblies With Lemo panel type connectors.
FUW: Cable plug with cable gland.
PUW: Cable socket with cable gland.
Note that pricing shown is for the cable assembly only, supplied loose-coiled or on non-returnable transit reels. Cable drums with external 'tail' supports should be ordered separately, see Canford cable drums - Steel drum, see Canford cable drums - Rubber drum or see Canford Skeleton cable reels - Trolley and Reeling stand. See also the Canford cable drum capacity calculator in the Technical section, to select the correct drum.
Canford's fibre termination facility is certified by Lemo for termination of the Lemo SMPTE304 connectors.
As part of our final test process Canford carry out both insertion and return loss measurement, as well as interferometry measurement on all Fibre terminations. Although some termination facilities do not use interferometry and rely merely on insertion and return loss testing to determine results Canford will always carry out interferometry as standard. Test results including 3D imagery of terminations can be supplied upon request.
Interferometry measures three critical dimensions required for continued reliability, end shape (radius of curvature measured in mm), the polished apex offset (measured in um) and fibre height (measured in nm). These three parameters all fall within tight industry standards which guarantees reliability when mating random connectors.
Ordering note: Custom lengths and connector variations are available, please contact the sales team for a quotation.
