1. SAFETY CONSIDERATIONS
1.1 Electric Shock Hazard
Electrical shocks due to faulty mains driven power supplies.
Whilst ever potentially present in any electrical equipment, such a condition would be
minimised by quality installation practice and thorough testing at:
a) Original assembly.
b) Commissioning.
c) Regular intervals, thereafter.
All test equipment to be in good working order prior to its use. High current power supplies
can be dangerous because of the possibility of substantial arcing. Always switch off during
disconnection and reconnection.
1.2 RF Radiation Hazard
“CAUTION: This equipment is approved for antennas mounted on fixed outdoor
permanent structures. A minimum separation distance of 2 metres must be maintained
between the radiating elements and any nearby persons. A maximum antenna gain of 21
dBi may be used. Operating this equipment without regard to these restrictions will result in
RF exposure levels above the limits allowed by FCC rules.”
This equipment complies with part 90 of the FCC rules. Any changes or modifications not
expressly approved by the manufacturer could void the user’s authority to operate the
equipment.
Antenna positions should be chosen to comply with requirements (both local & statutory)
regarding exposure of personnel to RF radiation. When connected to an antenna, the unit is
capable of producing RF field strengths, which may exceed guideline safe values especially if
used with antennas having appreciable gain. In this regard the use of directional antennas
with backscreens and a strict site rule that personnel must remain behind the screen while the
RF power is on, is strongly recommended.
RF radiation, (especially at UHF frequencies) arising from transmitter outputs connected to
AFL’s equipment, must be considered a safety hazard.
This condition might only occur in the event of cable disconnection, or because a ‘spare’
output has been left unterminated. Either of these conditions would impair the system’s
efficiency. No investigation should be carried out until all RF power sources have been
removed. This would always be a wise precaution, despite the severe mismatch between the
impedance of an N type connector at 50Ω, and that of free space at 377Ω, which would
severely mitigate against the efficient radiation of RF power. Radio frequency burns could
also be a hazard, if any RF power carrying components were to be carelessly touched!
Where the equipment is used near power lines, or in association with temporary masts not
having lightning protection, the use of a safety earth connected to the case-earthing bolt is
strongly advised.

1.3 Chemical Hazard
Beryllium Oxide, also known as Beryllium Monoxide, or Thermalox™, is sometimes used
in devices within equipment produced by Aerial Facilities Ltd. Beryllium oxide dust can be
toxic if inhaled, leading to chronic respiratory problems. It is harmless if ingested or by
contact.
Products that contain beryllium are load terminations (dummy loads) and some power
amplifiers. These products can be identified by a yellow and black “skull and crossbones”
danger symbol (shown above). They are marked as hazardous in line with international
regulations, but pose no threat under normal circumstances. Only if a component containing
beryllium oxide has suffered catastrophic failure, or exploded, will there be any danger of the
formation of dust. Any dust that has been created will be contained within the equipment
module as long as the module remains sealed. For this reason, any module carrying the
yellow and black danger sign should not be opened. If the equipment is suspected of failure,
or is at the end of its life-cycle, it must be returned to Aerial Facilities Ltd for disposal.
To return such equipment, please contact the Quality Department, who will give you a
Returned Materials Authorisation (RMA) number. Please quote this number on the packing
documents, and on all correspondence relating to the shipment.
PolyTetraFluoroEthylene, (P.T.F.E.) and P.T.F.E. Composite Materials
Many modules/components in AFL equipment contain P.T.F.E. as part of the RF insulation
barrier.
This material should never be heated to the point where smoke or fumes are evolved. Any
person feeling drowsy after coming into contact with P.T.F.E. especially dust or fumes
should seek medical attention.

1.4 Laser safety
General good working practices adapted from EN60825-2: 1994
“Do not stare with unprotected eyes or with any unapproved optical device at the fibre ends or
connector faces or point them at other people.”
“Use only approved filtered or attenuating viewing aids.”
“Any single or multiple fibre end or ends found not to be terminated (for example, matched,
spliced) shall be individually or collectively covered when not being worked on. They shall
not be readily visible and sharp ends shall not be exposed.”
“When using test cords, the optical power source shall be the last connected and the first
disconnected.”
“Use only approved methods for cleaning and preparing optical fibres and optical
connectors.”
Always keep optical connectors covered to avoid physical damage
Do not allow any dirt/foreign material ingress on the optical connector bulkheads.
The optical fibre jumper cable maximum bend radius is 3cm, any smaller radii may result in
optical cable breakage or excessive transmission losses.
Caution: Do not get them wet, the FO units are NOT weather proof.

2. OVERVIEW/SYSTEM DESCRIPTION
The AFL Off air Amplifiers for the Pasadena Blue line project are 2 way on-band RF
amplifiers. Their application is as an interface between the donor radio sites and the Fibre
optic receivers and transmitters which will extend coverage to the locations via the fibre optic
link. There are two units one designated for the ‘UHF1’ frequencies the other for the ‘UHF2’
frequencies.
Each unit is housed in an environmentally protected IP65 steel wall-mount case. Handles are
provided for carrying the unit and the door is fitted with locks. The unit interfaces with ‘N’
type female connectors for RF connections and heavy duty connectors for routing of AC
power supply input and alarm output wiring. Cable glands are provided for routing of the
Fibre optic cable in to the unit.
To provide adequate selectivity in the Downlink and Uplink paths, combline design bandpass
quadplexers and duplexers are used at the air interface ports. In addition each channel to be
passed is selected by a 15kHz or 25KHz Channel module which provides a high level of
rejection at adjacent channels. To provide the required gain to reach the required signal
levels, low-noise amplifiers (LNA’s) are used in each path, these being followed by power
amplifier modules in the uplink to provide the required intermodulation performance. Gain
adjustment is available locally using switched attenuators.
Note that “Downlink” refers to the RF path from the base station (donor site) to the FO
transmitter and that “Uplink” refers to the RF path from the FO receiver to the remote base
station.
