Overview

Introduction to the equipment

The Alcatel-Lucent 1626 Light Manager (1626 LM in the following) is the platform of

Dense Wavelength Division Multiplexing (DWDM) Multi Reach systems for Regional,

National, Pan-continental Networks.

The Alcatel-Lucent 1626 LM addresses terrestrial applications from Metro-Core (few

hundreds of kilometers) to Ultra Long-Haul (up to 4500 km) and unrepeatered submarine

applications (400 Km single span), from average capacity for regional networks up to

large capacity for pan-continental networks.

The Alcatel-Lucent 1626 LM is designed to address efficiently green field applications for

new networks and links as well as to upgrade legacy platforms without traffic

interruption. Carriers can keep their installed DWDM base and increase its capacity by

loading new wavelengths from the 1626 LM. This provides to carriers a state-of-art

technology and advanced features without wasting the investment previously granted.

System capacity

The Alcatel-Lucent 1626 LM provides a modular transmission capacity on a single optical

fiber by multiplexing:

up to 96 channels, 10 Gbps rate, 50 GHz grid in the Extended C-band (1530 nm -

1568.6 nm)

up to 32 channels, 10 Gbps rate, 100 GHz grid, in the standard C-band ( 1529.55 nm -

1561.42 nm).

System structureThe Alcatel-Lucent 1626 LM architecture is based on a standard or a compact shelf that

can be configured in different ways to support a variety of applications. The main building

blocks (interfaces, mux/demux, optical amplifiers, protection boards, ...) can be allocated

in the shelves in a very flexible way. As a result the footprint and the cost of the system

configuration is optimized.

The system structure is based on transponders, mux/demux and optical amplifiers. The

transponders are connected to optical Muxes/Demuxes which generate the main DWDM

signal (combined signal) and launch it in the fibre by means of optical amplifiers.

The Alcatel-Lucent 1626 LM supports the following main categories of 3R transponders:

Figure 1-1 Example of 1626 LM configurations in a WDM line

Flexible and scalable architecture

The 1626 LM design allows the customer to begin with a partially equipped

configuration (e.g.: 8 channels) that can be progressively upgraded as the traffic

demand grows, with a 8 or 4 chs channels mux/demux granularity. In particular, from

the initial configuration, the transmission capacity can be increased without

interrupting the existing traffic.

Unsurpassed platform density

Up to 16 x 10Gbps optical channels in a single shelf, up to 48 x 10Gbps optical

channels in a single rack. Up to 96x10Gbps system or up to 352x2.5 Gbps interfaces

are supported in only two racks.

Traffic Flexibility via Optical Add & Drop functionality.

The Alcatel-Lucent 1626 LM provides the add/drop capability by means of

Channel OADM for 50 GHz compatible architecture providing

Add/drop up to 100% of the transported capacity

Independent management of each single channel

Optical pass-thru (no regeneration) of all the channels that are not extracted.

Band OADM for 50 GHz compatible architecture providing

add/drop up to 100% of the traffic

Optimized architecture for improved OADM cascadability

Optical pass thru (no regeneration) of all the bands that are not extracted

Time multiplexing functionality

The Alcatel-Lucent 1626 LM supports fully transparent G.709 compliant multiplexing

of four 2.5Gbps input signals into one 10 Gbps wavelength. Fully transparent

multiplexing is achieved via the G.709 defined mapping of four ODU-1 into one

ODU-2.

Multiplexing functionality of GbE input client rates is also supported by the 1626 LM

as direct mapping of nine GbE input signals into a 10 Gbps signal and of two GbE/FC

inputs into a 2.5Gbps signal.

Full C band tunable laser

The Alcatel-Lucent 1626 LM supports full C-band tunable laser functionality on 10

and 40 Gbps interfaces. This is delivering not only important cost saving in managing

the spare parts, but also a major reduction of the logistical issues associated to network

upgrade planning.

Raman amplification

Extension of achievable span performances is possible thru Raman amplification. This

is especially useful to mitigate the penalty associated to the presence of very long

spans in a link. Raman amplification is supported thru the interconnection to a

dedicated Raman shelf.

SFP (up to 2.5 Gbps) and XFP (10 Gbps) pluggable optics

They are optical transceivers that enable to customize the transponder user interface in

a very flexible way. The 1626 LM supports pluggable SFP standard compliant optics

for the client interfaces of 4x2.5Gbps Tributary Concentrator and ETHC1000 and for

the client and line interfaces of 2xGE_FC. XFP optics are supported by TRBD1191(client side) and ETHC1000 (line side).

1+1 Bidirectional Optical Protection.

The 1+1 optical protection provides complete protection of the optical path, including

cable, amplifiers, mux/demux and transponders. High reliability is obtained by

redundancy of the transmission HW. The additional following protection types are

planned in future releases:

1:1 OMS protection, devoted to the protection of both the cable cuts and Line

amplifier failures

SupervisionIn order to supervise all the NEs along a WDM path an optional Optical Supervisory

Channel (OSC) is inserted in a 1510nm out-of-band wavelength and added to the

aggregate signal. The OSC channel for Data Communication Channel (DCC) is 2

Mbs.

Multishelf configurations

Multishelf configuration management to support large capacity networks.

Configurations of up to 12 racks with 3 shelves are supported in current release.

Automatic laser control

This feature facilitates the loading of the system with a few number of modulatedchannels or to compensate for the loss of some modulated channels

Management Interfaces

The Alcatel-Lucent 1626 LM is fully managed by the Alcatel-Lucent 1350 Network

Management System, common to all members of the optical family for comprehensive

monitoring, supervision and control of the overall network.

The Alcatel-Lucent 1350 network management system comprises the Alcatel-Lucent

1353NM and 1354RM.

In this section the system configuration supporting the 50 GHz grid applications are

detailed.

The 50 GHz grid architecture is based on sub-bands that can be equipped with up to 8channels. The system capacity can be scaled up to a maximum of 12 bands for a total

capacity of 96 channels. Current release supports terminal configuration as well as Band

Ethernet or Fiber Channel clients aggregation, combination of ETHC/TRBD or 2

GBE_FC/TRBC can be implemented.

Up to 96 colored WDM signals (12 bands) are multiplexed in the line/aggregate

signal.

The fully equipped LT configuration requires three racks.

In the LT configuration the equipment is placed at both ends of point-to-point links. Theschematic representation of the LT configuration is reported in Figure 1-3, 1626 LM Line

Example of a Long Haul Line Terminal (50 GHz grid)

Figure 1-4 Line Terminal - Long Haul - 50 GHz grid

In Line Terminal configuration, up to 96 channels on a 50GHz grid, can be sent to the line.

The used BMDX is the BMDX1000 (band mux/demux).

When the Line Terminal is used in links with Band-OADM, up to 7 channels per band are

available. Moreover the BMDX1100 can also be used, instead of the BMDX1000.

ALCT is used to facilitate the loading of the system. The ALCT band is specified

according to the link design (default is B5). Typically one board is used in LT (but a higher

number may be used), in order to substitute the relevant missing CMDX(s). In case of 12

bands installed, no ALCT is needed.

The line terminal also supports a specific configuration for unrepeatered applications,

For T-OADM configuration, for each Add & Drop channel, the operator is able to choose

the transponder to perform the Add & Drop. As a consequence, in such configuration all

transponders are able to transmit/receive all of the 96 possible channels.

Y node configuration brings the capability to add and drop one or more wavelengths

to/from the aggregate signal in any of the three directions. It provides the ability to

establish a connection for any wavelength from one to any of the other two directions.

Thus each channel of the Y node configuration may be in one or more of the following

states:

Express_XY

The channel is transmitted from direction X to direction Y (and from direction Y to

direction X)
