OPERATION
The 1120 Bare Fiber Aligner is used to quickly connect bare optical fiber to a
test equipment optical connector. Before using the 1120, ensure that a 112X-
IMC or 112X-RMC Index Matching Cartridge is loaded into the 1120’s coupling
module (see previous section) and that the opposite end of the 1120 is connect-
ed to the OTDR or other test equipment bulkhead.
To couple a fiber to the test instrument with the 1120 Bare Fiber Aligner:
1. Strip at least 35 mm of coating from the fiber to expose bare glass and clean
the fiber with isopropyl alcohol and a lint-free wipe.
2. Either break or cleave the fiber at a point approximately 25 mm from the
coating shoulder.
3. Slowly insert the fiber into the end of the 1120 Bare Fiber Aligner coupling
module until it contacts the module’s internal connector ferrule. If an optical
connection is not accomplished on the first insertion, pull the fiber back about
1/8” and push it forward, again making contact with the connector. If a connec-
tion still cannot be established, completely remove the fiber and re-prepare the
fiber end.

MAINTENANCE
CLEANING
Occasionally you may have to clean the jumper connector (with red strain relief)
that is attached to the 1120 coupling module, and/or the ferrule assembly/metal-
lic sleeve inside the 1120 coupling module. For the 1120M or P aligners, first
pull the end cap (9) and attached coupling module assembly from the aligner
housing (do not pull the end cap more than 20 cm out of the 1120M housing).
To remove the connector (1) from the assembly, loosen the knurled retaining
ring (2) by rotating it counterclockwise and then pull the connector ferrule out of
the ceramic sleeve (3) inside the bulkhead housing. Clean the ferrule and then
