1. INTRODUCTION
Fiber optic BOAs are used to control power levels in
fiber optic cable (or lines) used in telecommunication
and CATV applications.
For application requirements for the BOAs, refer to
Application Specification 114-1129.
NOTE
i
Dimensions in this instruction sheet are in metric
units [with U.S. customary units in brackets].
Figures are not drawn to scale.
Reasons for reissue of this instruction sheet are
provided in Section 5, REVISION SUMMARY.
2. DESCRIPTION
Configured as a connector with a plug (or ferrule) at
one end and a receptacle at the other end, the BOA
can be installed at a distribution patch panel, in line
between two patchcords and an adapter as shown in
Figure 1, or directly at the receiver interface. BOAs,
like patchcords, are available with ends that thread,
snap, or twist to fully connect.
3. INSTALLATION
The following steps describe installation of the BOA
in line between two patchcords and an adapter—
basically, the same steps apply to installation at a
distribution patch panel and installation directly at the
receiver interface.
DANGER
STOP
Never look into the end of a patchcord or BOA
when the connecting ends of the fiber optic cable
are attached to an optical power source. Infrared
light is invisible but can damage eye tissue.
1. Identify the line to be attenuated. Disconnect the
patchcord from the adapter.
2. Remove the protective cover from the plug end of
the BOA.
3. Inspect and, if necessary, clean the end face of
the BOA and the end face of the patchcord
according to Section 4.
CAUTION
!
IT IS EXTREMELY IMPORTANT that ALL end
faces are clean BEFORE mating.
4. Align the plug end of the BOA with one end of
the adapter, and insert the BOA into the adapter.
Refer to Figure 2, Detail A. Make sure that the BOA
is fully connected. For a BOA with threaded ends,
finger-tighten the BOA to a torque of approximately
0.23 N-m [2 in.-lb].
NOTE
i
For BOAs with a key, make sure that the key is
aligned with the key slot of the adapter.
CAUTION
!
To avoid damage to the adapter, patchcord, or
BOA, DO NOT use any tools to tighten the BOA.
5. Remove the protective cover from the receptacle
end of the BOA.
6. Inspect and, if necessary, clean the end face of
the BOA and the end face of the patchcord
according to Section 4.
CAUTION
!
IT IS EXTREMELY IMPORTANT that ALL end
faces are clean BEFORE mating.
7. Align the end face of the patchcord with the
receptacle end of the BOA, and insert the
patchcord into the BOA. Refer to Figure 2, Detail B.
Make sure that the patchcord is fully connected.
For a patchcord with threaded ends, finger-tighten
the patchcord to a torque of approximately
0.23 N-m [2 in.-lb].
