MST Application
In a typical FTTP network, the MST is installed between the Fiber Distribution Hub
(FDH) and the subscribers as shown in
Figure 3
. Network feeder cables transport the
optical signals from the signal source to the FDH. At the FDH, optical splitters are used
to divide the optical signals for distribution to the subscribers. Distribution cables
transport the optical signals to the MST’s which are located at points that allow service
to be provided to several subscribers. Drop cables transport the optical signals from
each MST to the individual subscribers.
Figure 3. Typical FTTP Network
The MST is designed for outdoor applications and can be installed in a hand-hole or
pedestal; mounted on a utility pole or over-head cable; or secured to any flat surface. A
universal mounting bracket is included with each MST. The MST meets the
environmental criteria specified in the referenced specifications and can withstand
direct exposure to extreme temperatures and humidity, is resistant to water penetration
during flood conditions or heavy rains, and is also chemical and corrosion resistant.
Under normal conditions, the MST enclosure should never require disassembly.
However, a kit and instructions are available if it is necessary to open the enclosure to
replace a broken internal optical connector.
