XDM-300 Platform Overview
ECI Telecom's XDM-300 is a powerful flexible MSPP optimized for metro
networks. It supports multitude technologies in a cost-effective fashion to
address the market increasing traffic demands.
The XDM-300 supports scalable STM-1/4/16/64/OTN aggregates and flexible
access topologies. It offers a wide range of features and benefits including:
|Carrier class Ethernet as well as traditional SDH voice-centric services.
|Gradual in-service capacity expansion based on service provisioning needs.
An optical connection operating at a specific STM rate can be upgraded
from STM-1 to STM-4/STM-16/STM-64 without affecting traffic.
|Sublambda grooming resulting in high utilization of existing fibers and top
efficiency in transmission of different types of services.
|Support of CWDM, OADM, transponder, combiner, OFA, and other
optical cards and modules used to process, amplify, and monitor
multichannel signals.
The XDM-300 shelf was designed to facilitate simple installation and
maintenance. Hot insertion of cards and modules is allowed, supporting quick
maintenance and repair without affecting traffic.

For a detailed description of the XDM-300 platform, see the XDM Converged
MSPP and All-Range™ ROADM General Description.
Figure 1-1: XDM-300 shelf
XDM-300 I/O Protection Options
The XDM-300 shelf boasts an extremely high modular design with two module
cages, one in the upper part, one in the lower part, and a card cage in the
middle. An expansion TPU shelf that adds protection capabilities to the I/O
modules, can be mounted on top and under the shelf. An expansion OCU shelf
that adds CWDM networking capabilities to the XDM-300, can be mounted on
top of the upper TPU or directly on top of the XDM-300 shelf.
Protection of I/O modules in the upper and lower module cages is supported.
CAUTION:When the XDM-300 shelf is to be installed
vertically, pay attention to position the shelf with the FCU300
facing downwards, to ensure proper air flow to the XDM-300.
Basic XDM-300 Shelf
The basic XDM-300 shelf is housed in a 246 mm deep, 443 mm wide, and
350 mm high equipment cage. The shelf consists of two module cages, one in
the upper part, the second in the lower part, and a card cage in the middle. Each
module cage can house up to 8 I/O modules, totaling 16 modules in the entire
shelf. The card cage accommodates two MXC300 cards (main and protection),
an External Connection Unit (ECU300 or ECU300_F), and two wide I/O cards.
When I/O cards are not used in the wide slots, they can be adapted to
accommodate one SIM16_1 module each, using a mechanical adapter.
