WARNING:
Unterminated optical connectors may emit invisible laser radiation. Avoid
direct exposure to the beam. Do not view beam with optical instruments.
Use of controls or adjustments or performance of procedures other than
those specified herein may result in hazardous radiation exposure.
!
CAUTION:
Take care to avoid damaging the LEDs that protrude through the opening
in the faceplate of the
OLIU
.
!
CAUTION:
The
26G-U/26G2-U OLIU
requires a 15 dB LBO when it is looped on
itself. The
29G-U/29H-U OLIU
requires a 10 dB LBO when it is looped on
itself.
!
CAUTION:
Avoid excessive bending of the optical jumper used to loop the
OLIU
on
itself.
!
CAUTION:
All optical fiber connectors and couplings should be properly cleaned
[DLP-527]
. Signal performance may be degraded if the connectors and
couplings are not cleaned properly.

are shipped with 0 dB SC-type universal LBOs installed. The 0 dB LBO
must be replaced with a 15 dB LBO when the
26G-U/26G2-U OLIU
is
looped on itself or a 10 dB LBO when the
29G-U/29H-U OLIU
is looped
on itself.
NOTE:
It may take from 15 seconds to 3 minutes and 25 seconds for the FAULT
LEDs to stop flashing, depending on the setting of the signal degrade
threshold (–5 to –9).
