- SFP COTS tests:
- Manoel will be present the results at TWEPP
- The full report to be shared before with everyone here: action @Manoel Barros Marin
- MUXes:
- Radiation tests to be performed this year
- Jan confirmed it is foreseen by the end of September
- System tests to be performed with final components next year (2024): CWDM is not really a standard and we need to test the chain to exclude issues
- it is reassuring that we have at least a set of 2 vendors that seem compatible with our specs and potentially doses
- We need 2 types of setup
- "optics" (demo system with custom components): ESE, to make sure Muxes are compatible with the components
- "functional test": BPM and BLM could build the chains (to test with the SFPs)
- Francois suggested that some tests could be performed already with the candidates if we have
- Christos mentioned they have a full set up for the test with the final components
- Andrea mentioned that for the BPM the final set up doesn’t exist yet, but there are boards for the qualification of components that can be reused for this:
- The SFP loopback test board for the compatibility of the optical part
- The ADC test board for a 2nd stage full system compatibility test
- Manoel mentioned that one of the ADC was interfaced with a VTRx, but a multi mode one: the results were good, even tho they could not control/program the emphasis filters
- This proves that the electrical interface is ok
- Need of some VTTx to actually test the MUX tho
- Few candidates have been identified by Manoel for the reception part, but mostly SFP
- Jan suggested there should be ‘receiver only components’, but Manoel said those seem exotic and therefore more expensive than standard one by more than a factor 2 (better to have and not use the transmitter)
- Andrea said we could order a few samples of the current candidates already for the MUX tests: action @Manoel Barros Marin
- 2024 preparation of market survey and IT
- Jan wants to discuss the preparation of this with Josh but in a separate meeting. Josh accepted: action @Jan Troska to organise this meeting
- The actual purchase should happen in 2025
- Thibaut: Spending profiles can be reshuffled as long as we foresee it in advance and not in the same calendar year
- the budget for the BPM needs reprofiling: action @Andrea Boccardi
- The BLM profile already have the muxes in 2025
- Radiation tests to be performed this year
- TOSA IT already out: deadline set to the 29th of September
- ROSA:
- First technical discussion with Lauri and the new ALBIS people yesterday to remind them the outgassing issue
- Subcontractor (EZConn) to come back with a new way of building the ROSAs in a few weeks.
- Jan asked for metallic assembly and waiting a reply for the company
- The GBLD yield seems to be the same of the previous production, with some indication that the quality of the chips (jitter) could even be better for this batch
- The yield seems the same also between 5 and 10 Gbps using pre-emphasis
- Full series from in house modules (1300) will be done in a couple of weeks: this will give us a better projection of the yield to expect for the 5 and 10 Gbps operation modes
- The test bench required some changes. Both BLM and BPM allocated 30k (in total 60k) for this in the budget between 2023 (20k) and 2024 (40k)
- The rential cost for the instrument was charged on the BPM code
- The purchase of the missing elements will be charged on the BLM code (64726)
- Sophie asked a flow chart for the next steps in the project: action @Antonio Cristiano
