The ALICE Detector Data Link (DDL) is a high-speed optical link designed to
interface the readout electronics of ALICE sub-detectors to the DAQ computers. The
Source Interface Unit (SIU) of the DDL will operate in radiation environment. Tests
showed that configuration loss of the ALTERA APEX II FPGA device used earlier on
the DDL SIU card is only marginally acceptable. We developed a...

We have developed a radiation-hard optical link for the ATLAS pixel detector at the
LHC at CERN. The driver and receiver chips are implemented in 0.25 micron CMOS
technology using enclosed layout transistors and guard rings for increased
radiation hardness. The former drives the Vertical Cavity Surface Emitting Laser
(VCSEL) diode to transmit 80 Mbit/s data from the detector. The...

The on detector optical links for the SCT have been produced and mounted on the
detector. Most of the off-detector opto-electronics has also been produced and has
been used to successfully read out modules assembled on barrels and End Cap disks.
Many problems were encountered during the production and these will be described.
The lack of modularity in the system design has been a major...

Approximately 15,000 analog optical transmitter modules with 2 or 3 channels each
will be installed in the CMS experiment to read out the Silicon Strip Tracker.
These Analog Optohybrids were produced in Austrian and Italian industries from mid-
2003 to mid-2005.
After assembly, each unit was thoroughly tested for electrical and optical
properties and all results are stored in the CMS...
