... HFBR/HFCT-591XE will operate in both configurations recommended bypass capacitor for additional low frequency noise filtering. The signal detect output on the HFBR-591XE contains an internal 1.8 k pull up resistor. The output stage on the HFCT-591XE pull configuration and therefore does not require an external pull up resistor. ...

... In addition metals that can build up insulating oxides, such as aluminium, should be avoided. The SFF grounding scheme is de- scribed in the relevant data sheets important to note that the HFBR/HFCT-591xE transceivers have separate V planes but common CC ground planes for the transmitter and receiver sections. ...
