PlexSIS Fibre Optic Systems from SIS LIVE

PlexSIS Fibre Optic Systems

1u 19 inch rack mounted PlexSIS

PlexSIS, SIS LIVE’s fibre optic system, lowers the cost of distributing digital video and simplifies the setup of cable systems.

Providing transport of 8 SDI (HD, 3G and SD) signals over a single optical fibre, and up to 16 when linking two systems, PlexSIS is available in two configurations (8 channels on one direction or 4 in both directions), with each of these available in the high or low wavelength band. All SDI ports are fully reclocked, meaning that jitter caused by long coaxial runs will not affect the maximum optical run length and vice versa.

The front panel OLED screen displays optical power, SDI signal presence, temperature and system voltages, and alarms can be set up to trigger an audible tone or relay contact closure, giving peace of mind when it comes to detecting and resolving distance, grounding and interference issues.

The system has been extensively used in the field by SIS LIVE at some of the largest outside broadcasts in history to ensure that its effectiveness and reliability are unparalleled.


  • Compact 1U chassis
  • Two configurations available - 8 SDI over 1 fibre, 4 SDI in each direction over 1 fibre
  • Automatic cable equalisation
  • Multi-rate reclocking with automatic rate detection
  • Both AC and DC power inputs provides flexibility and power redundancy
  • Supports SD, HD and 3G SDI
  • Wide DC input range 9-36V
  • Local monitoring of SDI signal presence, optical signal strength etc on full colour front panel display
  • Configurable audible and relay contact closure alarms
  • Optical expansion port - two systems can be combined to provide transport of 16 SDI signals over a single optical fibre
  • Both systems available in upper or lower optical bands
  • Lower band avoids water peak wavelength to give maximum optical reach over conventional fibre (ITU-T G.625 A&B)
