13.2.2.2 Description of the Fiber Installation
Here the interfaces related with the built-in SDH are FIBER-3 and FIBER-4. FIBER-3
is the optical transmission input interface and FIBER-4 is the fiber transmission output
interface used for networking with the adjacent BTS.
Fig. 13.2-3 shows the position for installing the water-proof fiber at the bottom of the
micro-BTS cabinet and that for connecting and laying out the water-proof fiber inside
the cabinet.
The water-proof connector of the fiber is connected with the cabinet body in the similar
way to the fiber connection when the micro-BTS connects with the RF remote station.
The fiber is laid out in a naturally way after it goes into the cabinet and is connected
with the optical module on the SDH.
