Fujitsu 1FINITY L100 User Manual

The postoutadj design value for the network is calculated during network design and planning process.
Postoutadj value range is within –15.0…0.0 dB. The default value is 0.0 dB. Seng should be implemented in the
inial system turn-up.

OSC Power Adjustment
Release 19.1.1 introduces OSC power adjustment feature to reduce the impact of an OSC signal on the trac
signal transmit distance in a network. An OSC signal may cause Cross Phase Mixing (XPM) that is one of the root
causes of reducon in the signal transmit distance.
The OSC power adjustment feature enables the L100 Blade to place an external PAD between the 100 Mb/s OSC
SFP (FC9581B62F) and the OSC port. This PAD reduces the impact of an OSC on the signal transmit distance. The
eecveness of the PAD depends on the span loss and the ber type.
Important: Fujitsu does not recommend using third-party OSC SFP module because the power of
third-party OSC module is not guaranteed.

Critical Data Storage Feature
The purpose of Crical Data Storage Feature (CDSF) is to provide for the automac recovery of specic NE
management interfaces when both the primary and secondary NE databases are found to be corrupted aer an
NE reset. Using the recovered NE management interfaces, the user may address the corrupted database by
restoring it from an externally stored backup le. 1FINITY management interfaces can be recovered as long as NE
is not power reset.
CDSF is a crical data segment feature which allows DCN connecvity up for the L100 Blade even if the NE
database is corrupted. The user can sll log on to the NE remotely and restore database instead of doing truck
roll.
If the primary and secondary databases are corrupted, the NE raises a database corrupon alarm.

Automatic Software Download
The automac soware download feature automacally updates a tributary blade soware when the tributary is
spared or in-service upgrade is performed. The automac download is supported when the Main blade with
Release 2.5 or later is connected to the tributary blade with Release 2.4.1 or later.
