The TFC distribution network is based on the CERN TTC system developped
in the RD12 project. The LHCb TFC system deploys the following TTC
components:
-
TTCmi: LHC machine interface
for timing signals
-
TTCtx: Optical transmitter
-
TTCoc: Optical fan-outs 1:32
-
TTCrx: Receiver chips
The TTCtx is a single
mode transmitter and the TTCoc is a single mode splitter, so please note
that all fibres used should be of the single-mode type with ST/ST
connectors. They may be ordered from from the TS/EL group (contact
Luit.De.Jonge@cern.ch or
Stephane.Casenove@cern.ch).
All TTC fibres between
the TFC system and the TELL1 (including trigger electronics etc in the
barracks) will be take care of centrally. All fibres between the TFC
system and the TTCoc's in the patch racks close to the detector will
also be take care of centrally. However, the sub-detector people
should provide all fibres between the TTCoc and the TTCrx's located on
the L0 Front-End electronics and alike.

single-mode fibre patch cords that you may order from the TS/EL group is
