Installing and Routing External Fibers
130
Do not look or stare into optical fibers directly without eye protection.
Route the external inter-office fibers properly on the ODF before leading them into a cabinet.
After the fiber installation, insert fiber plugs in idle ports and cover idle fibers with fiber caps.
The open corrugated pipe cannot be loaded with too many optical fibers. A maximum of 60 fibers with 2 mm
diameter are recommended for an open corrugated pipe with 32 mm diameter. The length for the open corrugated
pipe to enter the cabinet is about 10 cm.
Internal cascading fibers have been routed on the fiber spools of a subrack before delivery. During onsite
expansion, spool internal cascading fibers and external fibers in the fiber management frames.
Area for routing
external fibers
For external fibers, preferentially route
extra fibers on the ODF if there are many
extra fibers. Only a small number of fibers
can be spooled in a fiber management
frame.
