Cablefree Availability of FSO
Importance of Fade Margin for FSO
• High Fade Margin required to combat bad weather
 Rain – low attenuation
< 9dB/km
 Snow – moderate attenuation
< 12dB/km
 Mist – moderate attenuation
< 12dB/km
 Thick fog – high attenuation
up to 100dB/km
• System features meet ‘5-nines’ criteria
• Ultra-sensitive APD receivers
• High Quality optics & filtering
• Automatic Transmit Power Control (ATPC)
Cablefree
FSO illustration of Fog Densities
No fog – Visibility well over 2km
Light fog – Visibility over 1km
Thick fog – Visibility 400m
For 99.999% Reliability: Plan for worst-case local Fog densities
Use CableFree’s Link Planning Tools
Cablefree
Cablefree ATPC – how it works
No fog – Visibility well over 2km
In clear conditions, the CableFree ATPC system
automatically reduces output power to a lower level,
down to 1/16 of maximum.
Overload of the receiver is avoided even in bright
sunny conditions
Light fog – Visibility over 1km
In moderate conditions, the ATPC controller turns
the power up to ensure optimum power received at
both ends of the link.
Sophisticated on-board software avoids overload or
drop-out
Thick fog – Visibility 400m
In bad conditions, ATPC can increase the power to
maximum output for a given product type.
Note: This means you can install a 4km FSO system
say at 600m, to increase availability beyond that
which a nominal 1km system could provide
Cablefree
Cablefree ATPC – with & without
CableFree link with ATPC switched off
A CableFree link without ATPC enabled, showing
significant variations in received signal level (RSSI).
RSSI variations can be caused by weather effects
such as fog, heavy rain, snow or dust storms; also
thermal effects, bracket movement and long-term
drift
CableFree link with ATPC
A CableFree Link with ATPC enabled in identical
conditions shows no variation in received power
(RSSI). The controller automatically adjusts the
transmitted power levels to ensure optimum signal
received at both ends of the link.
Optimum power levels mean minimum Bit-ErrorRate (BER) and reduced risk of overload
Cablefree
FSO Choice of Wavelength
Avoid the absorption peaks in the atmosphere
785nm
980nm
Slightly Greater fog penetration
• CableFree avoids
absorption caused by
water molecules
• There is no ‘magic
wavelength’ which
avoids fog – but …
• Longer wavelengths
allow higher safe
output powers
• A properly designed
link budget is the
most important
Cablefree
FSO Reliability
Equipment Reliability
• Solid-state Peltier cooling for long laser life - MTBF >20yrs
• Use of multiple lasers and drivers - protects against possible
failure of semiconductor lasers
• Housings are water, moisture and rust-proof
• System design uses quality components specified for highreliability telecom systems
• Proven track record with over 2000 deployments worldwide
CableFree has a ‘fit-and-forget’ design philosophy. Cooling, Heating
& power management ensure reliability in all climates.
Management systems provide indication of any degradation
Cablefree
FSO & Laser Safety
What are the requirements?
• Avoid risk of retinal damage
• Output power –
Class 3B not acceptable, 1M is the accepted limit
• Large apertures are safer –
Avoid ‘point source’ emission
• Divergent systems are safer –
e.g. CableFree 0.5 degree
• Mounting locations –
e.g. roof parapets safer than through glass
Cablefree
Cablefree FSO performance
Quality Transmit Optics: Circular, Wide beam
CableFree Circular beam combats X & Y movement
Older product – Narrow Elliptical beam
Misaligns in wind, vibration & building movement
Wide beam – no need for complex auto-tracking
