Challenges of outside plant
deployments
Moving the DSLAM out of the central office
poses several new technical challenges.
The temperature and environmental requirements,
for example, are much more
stringent. Present-day installations primarily
operate in a central office environment with
a typical temperature range of -5°C to +45°C.
Outdoor plant deployments, on the other
hand, must be able to operate in non-climatecontrolled
environments where temperatures
can range from -40°C to +65°C.8
