Beskrivelse av artikkelen

These self-normalling, mid-size, ‘mini-WECo’ style video jackfields pass uncompressed, 1080p HDTV video up to 3Gb/s (SMPTE 424M). The compact design fits 32 channels into 1U making them ideally suited to systems incorporating high density routers. The nickel plated, aluminium alloy jack modules and unique sealed rotary switch make these panels particularly suitable for use in trucks and flightcase systems where weight and the risk of dust contamination, are serious considerations.

The jack pairs are housed in rugged diecast aluminium clam-shell housings, and incorporate hermetically sealed, double reverse-action, rotary micro-switches, mounted on a screened PCB and rated at 30,000 operations. Two precision 75 ohm metal-film resistors offer near perfect signal-path termination. Jack modules are secured by front-panel screws, permitting simple module exchange. Modules have a manufacturer’s lifetime guarantee.

Technical Specification:

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.
