< < | Optical components used for testing the AMC13.
CDAQ |
> > | The AMC13 requires at least one SFP in the bottom site (for TTC) and typically
1-3 different type SFP in the upper 3 sites for DAQ. See sketch below.
The TTC SFP for all new AMC13 should be the 400Mb/s capable type (JDSU or Finisar below).
The CMS TCDS protocol now used requires 400Mb/s for the return data sent by the AMC13.
The DAQ SFP currently (as of LHC Run 2 in 2015) run at 5.0Gb/s, but we plan
to upgrade to 10Gb/s soon so ideally all AMC13 should have 10Gb/s capable SFP installed.
For the g-2 experiment, 10Gb/s is required. Confused? Me, too! |

| For the TTC receiver, we use an SFP 155-Mbps 1300nm transceiver. Suppliers:
- LFP105 from blackbox.com ($70 each) – Discontinued as of June 2012
- HFBR-57E0LZ from Avago (Digi-Key has them).
