Introduction

 

 

The main features are as follows: 

  Dual channel, video input to optical fibre output operation 
  Class 1 FDA and IEC60825-1 Laser Safety compliant 
  Single or multi-mode fibre operation – meets SMPTE 297-2006 short-haul 

specification 

  Optional coarse wavelength division multiplexing (CWDM) lasers available with a 

choice of ten different wavelength pairs 

  270Mb/s to 2.97Gb/s serial digital compliant to SMPTE 259M, SMPTE 292M and 

SMPTE 424M 

  Following video standards supported: 720p 50/59.94/60Hz, 1080p 50/59.94Hz, 1080i 

50/59.94/60Hz, 1080p 23.98/24/25/29.97/30/50/59.94/60Hz, 1080PsF 

23.98/24/25/29.97/30Hz, 2048x1080p 23.98/24/25/29.97/30Hz*, 2048x1080PsF 

23.98/24/25/29.97/30Hz* 

(*= YUV 4:2:2 10 bit)

 

  Two equalised and reclocked input loop-through outputs per channel 
  Capable of achieving distances in excess of 10km with single-mode fibre, depending 

on cable quality and number of connectors and splices 

  Remote warning indications of laser level fault (actual failure) and laser bias fault 

(imminent failure)  

  DVB-ASI compatible, all outputs positive polarity 

  Up to 20 FTX-VF cards in a Vision 3 3U frame
