Optical components used for testing the AMC13.

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 high-speed (SFP+) transceivers, we suggest HP AJ716A 8Gb Fibre Channel SFP+ transceiver. We bought a couple from serversupply.com ($85 each or so).

  • 57D9AMZ from Avago (CMS CDAQ, only works to 8.2 Gb/s)
  • HP AJ716A 8Gb Fibre Channel SFP+ transceiver. We bought a couple from serversupply.com ($85 each or so).
 These are 850nm MMF Duplex LC connector type.

160/400Mb/s TCDS

Line: 25 to 35
 
JDSU JSH-12L1DD1 USD 38 / 4 weeks   Recommended by Jan Troska
Finisar FTLF1318P3BTL USD 65 / Stock Gigabit Ethernet up to 1.25Gb/s

These are obsolete and should only be used for lab testing or loop-back.
 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).
