3Gb/s 1080p HDTV, 1.5Gb/s 1080i HDTV, SDTV, Analogue and Unbalanced 75ohm AES Audio
The connectors are a completely new version of the MUSA, re-designed for 3G and 1.5G high definition, standard definition and analogue video applications. The performance exceeds the requirements of SMPTE292M and SMPTE424M making them suitable for composite and component video, 270 Mb/s SDV and uncompressed 1080i or 1080p HD-SDI video up to 3Gb/s. Also suitable for unbalanced 75ohm AES digital audio. The connectors are straight-through, non-normalled, and require U-links or patchcords. Rear connection is via 75ohm BNC sockets. Connector configurations are 2-rows in 2U standard, or 4-rows in 3U high density.
The simplicity of the one-piece contacts in both panel connectors and U-links, and the non-normalled, U-link concept, means there are no complex moving parts or switch contacts, offering excellent reliability even when subjected to vibration. The body parts are nickel-plated and centre contacts are gold plated giving a smooth mating action and overcoming the ´sticktion´ and tarnishing of the now obsolete silver MUSA. Solid interface insulators prevent dust ingress meaning dust caps on unmated ports are unnecessary.
Panels are manufactured from a rigid aluminium extrusion and are fitted with two lacing-bars and two 7.5mm snap-on designation strips for which AutoCAD templates are available from the Tech Zone at www.canford.co.uk or from Technical Support. Depth behind panel, including lacing-bar, 180mm.
Available finished in Dawn Grey (BS4800-10A03) or Black as standard, other colours and connector layouts are available to special order but may be subject to an MOQ.
Optional accessories: 2-row 2U and 4-row 3U panels require Canford 4402 2U size U-links, see Canford MUSA U-Links - 3G HD-SDI. Flexible patch cords, see Canford MUSA HD 3Gb/s 1080p Patchcords. Spare 432mm designation-strip paper (not suitable for printers) and covers, see Designation strips - snap on.
Recess rack-mounting brackets are available to recess panels within the rack, see Canford Rackbracket - Recess mounting brackets.
SMPTE 292M & 424M Standards
SMPTE 292M is a standard published by SMPTE which allows for bit-rates of 1.485 Gb/s, and 1.485/1.001 Gb/s. These bit-rates are sufficient for to transport uncompressed High Definition video. This standard is usually referred to as HD-SDI and is one of a number of standards that define a Serial Digital Interface based on a coaxial cable, intended to be used for the transport of uncompressed digital video and audio in a television studio environment. SMPTE 424M develops SMPTE292M allowing for bit-rates of 2.970 Gb/s and 2.970/1.001 Gb/s over a coaxial cable or connector panel. These bit-rates are sufficient for uncompressed 1080p video at 50 or 60 frames per second often referred to as 3G HDTV.
The stipulated interface condition (cable & connector) are:
SMPTE 292M - insertion loss 20dB or less at 750MHz - return loss 15dB or less at 1.5GHz.
SMPTE 424M - insertion loss 20dB or less at 1.5GHz - return loss 15dB or less at 1.5GHz and 10dB or less at 3.0GHz.
