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.

<img src="http://ohm.bu.edu/~hazen/CMS/AMC13/sfp_locn.png">

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!

%TOC%


---+++ 10Gb/s DAQ 

   * [[http://www.digikey.com/scripts/dksearch/dksus.dll?vendor=0&keywords=AFBR-703SDZ][AFBR-703SDZ]] from Avago ($120).  EOL as of 2/2014
   * [[http://www.digikey.com/product-search/en?x=0&y=0&lang=en&site=us&KeyWords=AFBR-709SMZ][AFBR-709SMZ]] is a replacement, same price

---+++ 5Gb/s DAQ

   * [[http://www.avagotech.com/pages/en/fiber_optics/storage/8g_fibre_channel/afbr-57d9amz/][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

After LS1 CMS will replace TTC hardware with TDCS.  This will use TTC protocol for downstream
compatible with existing system, but new 400MB/s 8b10b protocol for upstream.
Either of the following two may be used. 

| *Manufacturer* | *Part No* | *Price/Availability* | *Speed* | *Notes* |
| JDSU | [[http://www.jdsu.com/ProductLiterature/jsh-12l1dd1_ds_cms_ae.pdf][JSH-12L1DD1]] | USD 38 / 4 weeks | | Recommended by Jan Troska |
| Finisar | [[http://ohm.bu.edu/~hazen/DataSheets/Finisar/finisar_ftlf1318p3btl_industrial_temp_1.25g_rohs_compliant_long_wavelength_sfp_transceiver_product_specification.pdf][FTLF1318P3BTL]] | USD 65 / Stock | Gigabit Ethernet up to 1.25Gb/s | 1310nm SMF |

---+++ 160Mb/s TTC

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) &ndash; _Discontinued_ as of June 2012
   * HFBR-57E0LZ from Avago (Digi-Key has them).  

Cables are 62.5u multimode ST-LC type

We have shipped several AMC13 with the Black Box ST/LC cable (3m) P/N: EFN110-003M-STLC.

_NOTE:  these are all obsolete with the commissioning of the TCDS system_
