As the same, 100GHz frequency distance reflects to wavelength is very approximate
to 0.8nm width.
3.4.8 SBS Suppression Adjustment
SBS value is very important in 1550nm long-distance transmission system. Stable
continuous coherent light source, add +6 dBm optical power in the standard single
mode fiber may occur SBS phenomenon. Ultrahigh SBS threshold will reduce CNR
and CSO low-frequency indicators.
High SBS threshold will also influence self phase modulation (SPM) and reduce
high-frequency CSO indicator.
When meet the conditions, as far as possible to use a low threshold SBS.
4. Installing the Optical Transmitter
4.1 Receiving and Inspecting
As you unpack your unit, inspect the shipping container and equipment for damage.
Save the shipping material for future use. If the container or the equipment is
damaged, notify both the freight carrier and us.
CAUTION
:
To protect yourself from potential injury and to protect the
equipment from further damage, do not perform any
operational tests if the equipment appears to be damaged.
4.2 Precautions
Heed the following precautions when working with the
equipment.
Warning
Read the installation instructions before connecting the system to
the power source.
Attention
Avant
de
brancher
le
système

d'alimentation,consulter les directives d'installation.
Warnung
Vor dem Anschließen des Systems an die Stromquelle die
Installationsanweisungen lesen.
Warning
The plug-socket combination must be accessible at all times,
because it serves as the main disconnecting device.
Attention
La combinaison de prise de courant doit être accessible à tout
moment parce qu'elle fait office de système principal de
déconnexion.
