Pre-Terminated with PLC Splitter

Available pre-terminated with pigtails and up to two 1x32 PLC splitters, enabling one-step installation that reduces field labor and splice time.

Lockable Steel Enclosure

1.2mm cold rolled steel body with hinged lockable door protects fiber connections from unauthorized access and accidental damage in shared or public spaces.
