User Manual
• When positioning the TFAx remote unit, pay
attention that the placing of related antennas
should be decided in order to minimize the
Minimum Coupling Loss (MLC), so as to avoid
blocking.
• The TFAx remote unit is intended to be fixed on
walls, false ceilings or other flat vertical surfaces
(TKA installation kits are available, in order to
provide a protective cover for TFAx remote unit,
while making the TFAx installation easier and
faster).
Handling optical connections
• When inserting an optical connector, take care to
handle it so smoothly that the optical fibre is not
damaged. Optical fibres are to be single-mode
(SM) 9.5/125µm.
• Typically, Britecell Plus equipment is provided with
SC-APC optical connectors (other connectors may
be provided on request). Inserting any other
connectors will result in severe damages.
• Do not force or stretch the fibre pigtail with radius
of curvature less than 5cm. See rightward figure
for optimal fibre cabling.
• Remove the adapter caps only just before making connections. Do not
leave any SC-APC adapter open, as they attract dirt. Unused optical
connectors must always be covered with their caps.
• Do not touch the connector tip. Clean it with a proper tissue before
inserting each connector into the sleeve. In case connector tips need to be
cleaned, use pure ethyl alcohol.
