Performance of the CMS Tracker Optical Links and Future Upgrade Using Bandwidth Efficient Digital Modulation [article]

Stefanos Dris
2010 arXiv   pre-print
In order to preserve the large investments made for the current readout system, an upgrade path that involves reusing the existing optoelectronic components is considered.  ...  Corrective action was taken to reduce the gains and recover the lost dynamic range by lowering the optical receiver's load resistor value from 100Ω to 62Ω.  ...  This is well within reach of the LLD bias current range (up to ~55mA), and radiation-induced threshold increase can be compensated for.  ...
