Preparing for optical testing
Before testing on optical circuits using the
T-BERD ⁄ MTS 5800, you should be familiar with the following
items.
Considerations Consider the following before testing on optical circuits:
– Only use the SFPs and XFPs that shipped with your
instrument, or SFPs and XFPs purchased from JDSU as
accessories. A list of JDSU supported optics (trans-
ceivers) shipped with your instrument and is also avail-
able on the Help menu under Recommended Optics.
– Details concerning the SFP used for the currently
selected application are available on the Interface setup
tab.
WARNING: HAZARDOUS LIGHT EXPOSURE
Do not look directly into the optical output of the unit or at
the output of any optical cable or transceiver connected to
the unit. If a fiber optic cable is removed from a transmitting
connector or transceiver, cover the connector with the safety
cap to prevent inadvertent exposure to the laser output.
WARNING: RISK OF DAMAGE TO TRANSCEIVERS
When connecting the instrument to optical circuits using an
SFP or XFP, do not apply optical power that exceeds the
maximum optical power published as permitted by the trans-
ceiver manufacturer.
If you do not know the optical power of the applied signal,
use an attenuator when you connect to the circuit for the
first time, then remove the attenuator if you determine that it
was not necessary. Otherwise, the transceiver can be per-
manently damaged due to the “hot signal”.
A variety of attenuators are available for purchase as
options when you order your instrument.
