I did the folloing cabling:
-- From RF distribution amp. (f1 16.88MHz, in IOO rack) to EOM for f1 (on PSL table), 40m SMA cable** 
-- From BNC-Dsub convertor (ch13, in IMC rack) to PDA100A (on REFL table, not yet connected to PDA100A^#), 20m BNC cable
-- From Quad. I&Q demod. (ch1, in IMC rack) to RF PD (S_No. 2, on REFL table), 10m SMA cable 
-- From RF distribution amp. (f1 16.88MHz, in IOO rack) to Quad. I&Q demod. (LO for ch1, in IMC rack), 40m SMA cable**
-- From LSC RFPD interface board (ch.2, in IOO rack) to RF PD (S_No. 2, on REFL table, not yet connected to RFPD^$), 10m Dsub-9pin cable

**: 30m SMA cable fits more, but we don't have 30m SMA cable yet.
#: not to disturb other people's work using REFL PD signal
$: not to ditrub other people's work; in order to connect the power cable for RFPD, the switch of LSC RFPD interface board has to be once turned off, which would result in unlock of IMC
