The document provides details about an engineering team consisting of 4 members and their roles. It then outlines the steps required to prepare, connect, insert fibers, crimp connectors, cure epoxy, clean, polish and inspect fiber optic connections.

4. REMOVE THE OUTER COATING OF THE
FIBER CABLE
REMOVE ALL THE STRENGHT MEMBER
AND THE SUPPORTING MATERIAL
REMOVE INDEX GEL OR KEVLAR
STRIP THE COLOUR-CODED COATING (typ
250u)
CLEAN THE FIBER USING ALCOHOL

6.  Load the mixed epoxy into a syringe (unless it's pre-loaded
of course).
 Inject the epoxy into the back end of the connector ferrule.
 Insert the prepared cable into the connector such that the
bared fiber is inserted into the ferrule hole. Insert until the
cable seats inside the connector. The fiber will be
protruding out the front of the ferrule by typically ½ inch.
 Crimp: If the connector is being installed onto jacketed
fiber, a crimping operation is required to retain the
connector onto the cable strength members and jacket. This
is usually accomplished via use of a crimp sleeve and, in
order to retain the connector onto the cable's strength
members as well as the jacket, two crimps are typically
required.

7.  Insertthe bare fiber into the connector
 Perform crimping
 Cleaving (manual or auto)

8. PATCH
CORD

9. A patch cable or patch cord is
an electrical or optical cable used to
connect ("patch-in") one electronic or
optical device to another for signal
routing.
 Firstly, Crimping kevlar sleeve onto the
connector
 Slide the strain relief boot up to the
connector

11.  A fibre is a single short, usually unbuffered,
optical fibre that has an optical connector on one
end and a length of exposed fibre athe other
end.
 The end of the pigtail is stripped and fusion
spliced to a single fibre of a multi-fibre trunk to
break out the multi- fibre cable into its
component fibres for connection to the end
equipment.
 Pigtails can have female connectors and be
mounted in a patch panel
 A plastic boot is normally used for strain relief
and protection from moisture.

light propagation

aluminum oxide

more recent APC (Angle Polished Connector).

17. 2. Surface polish

18. 3. Fiber optic micro polisher

19. •Toinspect the quality of the fiber
surface.
•Using a microscope

22.  Insertion Loss & Return Loss
 Return Loss are two importance data to
evaluate the quality of many passive fiber
optic components,such as fiber optic
path cord and fiber connectors, etc.

23.  Insertion Loss refers to the fiber optic light loss
coused when a fiber optic component insert into
another one to from the fiber optic link. Insertion loss
can result from absorption, misalignment or air gap
between the fiber optic components.
 Return Loss is the fiber optic light gets reflected
back at the connection point. The higher return loss
means the lower reflection and better the connection.
According to industry standard, Ultra PC polished
fiber optic connectors return loss should be more
than 50dB, Angled polished generally return loss is
more than 60dB. PC type should be more than 40dB.
