1. System Overview
This chapter covers the following main topics:
The LightPointe system
Link head devices
Laser safety
1.1. The LightPointe FlightLite System
1.1.1. Free-Space Optical Transmission
LightPointe wireless optical systems communicate using single or
multi-beam infrared light transmission (invisible to the human eye).
The systems require true line-of-sight between locations or relay
locations (hopping points) and operate in high and ultra-high
bandwidths.
Figure 1-1: Typical FL 100 / 100E Installation and Connections
The link head on the transmission side transmits a narrow infrared
light beam carrying the data received from the network interface. The
link head on the opposite side receives the beam, filters the optical
signal, and places it on the network interface on the opposite end. The
system is capable of operating in a full-duplex mode, transmitting and
receiving the entire bandwidth of data simultaneously.

1.1.2. Typical Applications
Typical system applications include the following:
LAN Extension
10/100 Ethernet connectivity
1.1.3. Network Interface Connectivity
The LightPointe FlightLite 100 / 100E can support any current network
architecture using Ethernet or Fast Ethernet Unshielded Twisted Pair
cabling.
1.1.4. Transmission Method
The FlightLite 100 / 100E systems use a single transmitter and a single
receiver for bidirectional full data rate transmission through space. The
system operates as a “piece of fiber” through the air.
Transmitter Components
The linkhead receives electrical 10/100tdata traffic from the network.
The electrical signal is used to modulate a high power laser source that
transmits an infrared beam into free-space.
Receiver Components
The receive amplifier converts the infrared signal coming from free-
space into an electrical signal by using a highly sensitive photo diode.
This amplified receive signal is sent to the opposite network device
interface on a standard RJ 45 Category 5/6 cable connection.

1.2. Laser Safety
LightPointe optical systems use semiconductor lasers as transmission
sources. You must be aware of corresponding laser safety regulations
and take the necessary precautions to avoid close direct exposure to
the laser beam. The infrared laser beam is invisible and has the
potential to penetrate to the retina and cause thermal damage.
The FlightLite optical laser communication systems use a Class 1M
laser in accordance with the international laser safety standard IEC/EN
60825-1 A2:2001.
Familiarize yourself with laser safety regulations and strictly enforce all
necessary precautions.
Warning: Do not look directly into the laser aperture from a
short distance. Never use any optical instruments to
view the laser beam.
When using the built-in telescope, you must be aware of the
appropriate safety distance (refer to Table 1-2). For distances below
the safety distance the operator must wear appropriate eye-protective
laser safety glasses. These distances assume an exposure of more
than ten seconds.

Caution: Use of controls or adjustments or performance of
procedures other than those specified herein may
result in hazardous radiation exposure.
Caution: This is a Class 1M Free Space Optical
Communication System (FSOCS) transmitter and
may be installed in unrestricted, restricted or
controlled locations. For additional details, please
refer to IEC 60825: SAFETY OF LASER PRODUCTS
Part 12: Safety of free space optical communication
systems used for transmission of information.

505-016300-00000 Rev A
Unrestricted locations are those areas that are normally accessible to
the public (e.g., unrestricted areas of rooftops, public areas at ground
level, open areas of offices and industrial premises, etc.). To install a
LightPointe Communications FSO system in an unrestricted location,
the link head must be installed 3 meters high or higher above the
surface of the unrestricted area or must be 1 meter or closer to the
edge of the unrestricted area. If a LightPointe Communications FSO
system is installed in an unrestricted area, a warning sign must be
posted that states “Do not use binoculars, telescopes or other
optical aids to view the FSO link heads.”
Restricted locations are those areas that are normally inaccessible by
the general public (including workers, visitors, and residents in the
immediate vicinity) by means of any administrative or engineering
control measure but that is accessible to authorized personnel (e.g.
maintenance or service personnel including window cleaners in exterior
locations) that may not have laser safety training. There are no
special requirements for a LightPointe Communications FSO system
installed in a restricted area.
Controlled locations are those locations where any kind of engineering
or administrative control measure is introduced to make it inaccessible
except to authorized personnel with appropriate laser safety training
(e.g., tower-mounted terminals, fenced/secure areas of rooftops,
locked rooms with strictly-controlled access, etc.). There are no
special requirements for a LightPointe Communications FSO system
installed in a controlled area.
The laser system shall be installed in accordance with ANSI Z136.1
control measures (engineering, administrative, and procedural
controls).
1.2.1. Laser Safety Labels
All relevant labels are affixed to the inside of the link head near the
laser aperture.
The warning labels are affixed to the outer shell of the link head.
Caution: Do not modify this certified laser product.

Direct ±12 to ±48V
DC
The linkhead will accept any DC input voltage from 12 to 48
Volts. If there is a local DC power supply, UPS or battery
plant, power the linkhead from the input pins on the rear
panel using the connector supplied with the linkhead
The most straightforward way to power the linkhead is with the Power
Over Ethernet power inserter. This eliminates the need for AC power
run to the mounting location of the linkhead – often on the roof of the
building.

The FPW PSE FL100 Power Over Ethernet injector consists of the
following components:
Figure 2-5: Power Over Ethernet Power Supply components
The Power Injector is equipped with a powered and a non-powered RJ
Port. Use the Non-Powered port to connect data into the Network
Equipment, hub, switch or router. The Injector is plugged into
commercial AC. The Injector places power over up to 100 meters of
Cat 5/6 Unshielded Twisted Pair wiring to power the linkhead from the
powered RJ Port.
