Product function
•
The Generic Splicing Shelf is a multi-purpose mechanical shelf assembly for the FIST fiber management system
in a rack environment.
•
The product is typically used :
-
to store splices of external cable to external/indoor cable
-
to store splices of external cable to pigtails.
-
to store splices of pigtails to pigtails
•
It can be installed in Tyco's FIST Racks and other 19" or metric (ETSI) rack sizes.
•
Accessories are available for termination of most common cable types.
•
Modular wraparound groove plates can be clicked in the UMS (Universal Mounting System) profile. They
provide the foundation for mounting combinations of SOSA2 (Splicing Only Sub-Assembly) and/or SASA2
(Splitter Array Sub-Assembly) modules. Typically, Single Circuit or ribbon fiber management is used.
•
Kevlar Termination Units (KTU's) can be mounted in the shelf to provide the necessary strain relief when
terminating common pigtail types.
•
The shelf is delivered with a metal hingable cover.
