Main / PROFLINK modular system / PLK-CH-1100

PROFLINK family PLK-1100 series 3G/HD/SD SDI/DVB-ASI changeovers provide protection for critical signal paths by switching between a main and a stand-by lines.

By combining different SFP modules with the same PLK-CH-1100 base changeover module one can obtain several combinations of input/output formats. The PLK-CH-1100 base changeover module is automatically configured by the SFP type being inserted.

User-presettable changeover delay: 0.1~10sec in 0.1sec increments. The changeback delay is three times longer that the changeover one.

Depending on the SFP type used the following I/O configuration are possible:
• with an e-SFP module - PLK-1100-EE, two electrical inputs, twin electrical output
• with an SFP/2Rx module - PLK-1100-FE, two optical inputs, twin electrical output

Features
• one unified changeover base module type for all I/O configurations
• I/O autoconfiguration according to the SFP type inserted
• automatic and manual changeober mode of operation
• signal analysis for changeover actions:
  • input signal loss
  • two or more EDH/CRC errors within a user-presettable interval
  • embedded audio group loss
• optional channel priority changeover mode
• signal reclocking for jitter reduction
• real-time optical input power monitoring (local and remote)
• real-time monitoring of SFP temperature, power consumption and supply voltage
• hot-swappable replacement of a changeover module without any re-cabling 

Mechanical description

PLK-CH-1100 base module is 92mm*32mm in size. A "PROFLINK" rack can accomodate 14 such modules. Modules are accessible from the frontal side of a rack, SFPs are accessible from the rear.
