Dwdm Channels; Dwdm Frequencies Allocation Plan In C-Band - Alcatel-Lucent 1850 TSS-320 Engineering Rules

Introduction

DWDM channels

1850 TSS-320 and 160 support the transport of DWDM channels at 10 Gbps. The exact
data rate depends on the particular mapping of the client. For details, refer to
interface at 10Gbps" (p.
The DWDM system is based on the 100 GHz channel spacing in the C-band, according to
the ITU-T G.694.1 Rec. In current release, the 16 channels of the L1 and L2 bands are
supported. The optical spectrum is shown in next
anchored to the 193.1 THz reference
The engineering rules are designed to accommodate all line rates available in PP10GSO
and PP10GE. They can be equipped with 16 different XFPs, each one tuned on one
DWDM channel/wavelength.
A DWDM channel must be regenerated if the OSNR or Dispersion limits are exceeded.
One DWDM unit is required to regenerate each direction of transmission.
