Cisco Enhanced Wave Division Multiplexing
Optical System Installation Note
This document provides installation instructions for the Cisco Enhanced Wave Division Multiplexer
(EWDM) passive optical system. The EWDM system combines 1 GB Coarse Wave Division
Multiplexing (CWDM) connections using SFPs and GBICs with 10 GB Dense Wave Division
Multiplexing (DWDM) connections using XENPAK, X2, or XFP DWDM modules. These DWDM
connections can either be passive or boosted to allow a longer range for the connection. The EWDM
passive optical system product numbers are listed in Table 1.

Overview
The Cisco EWDM passive optical system provides optical networking support for high-speed data
communication at 10 GBps for metropolitan area networks (MANs) using CWDM and DWDM optical
wavelengths in both ring or point-to-point configurations.
The Cisco EWDM passive optical system includes these components:
•Two-slot chassis
•OADMs
–
Eight-channel
–
Four-channel
–
Two-channel
•An optical amplifier
CWDM Two-slot Chassis
The CWDM Two-slot chassis (CWDM-CHASSIS-2) is a standard 19-inch chassis that is one rack unit
(RU) in height. Each CWDM two-slot chassis can hold two OADM modules or one OADM and an
optical amplifier. You can install the CWDM two-slot chassis in the same equipment rack as your other
switching equipment or in an adjacent rack.

Overview
EWDM OADMs
The EWDM OADMs are passive devices that can multiplex/demultiplex or add/drop wavelengths from
multiple fibers onto one optical fiber. The OADM connectors are labeled with the DWDM wavelengths
to be multiplexed/demultiplexed. All OADMs are the same size. Two OADM modules can be installed
in a CWDM two-slot chassis (CWDM-CHASSIS-2). There are three different types of EWDM OADM
modules
8-Channel Multiplexer/Demultiplexer (EWDM-MUX8=)
The 8-Channel Multiplexer/Demultiplexer (EWDM-MUX8=) allows you to multiplex/demultiplex eight
DWDM channels and combine them with up to 8 CWDM channels into one pair of fiber. Dual fiber is
used for both the network connection and the transceiver connections. The eight available wavelengths
are 1542.94 nm, 1542.14 nm, 1540.56 nm, 1539.77 nm, 1538.98 - 1560.61 nm, 1559.79 nm, and 1558.98
nm. The multiplexer/demultiplexer, shown in Figure 1, is equipped with a port that allows you to connect
to the booster amplifier.
Figure 1 Eight Channel Multiplexer/Demultiplexer (EWDM-MUX8=) Front Panel
Four-Channel and Two- Channel OADM (EWDM-OADM4= and EWDM-OADM2=)
The four-channel and two-channel OADM (EWDM-OADM4= and EWDM-OADM2=) allows you to
respectively add/drop four or two channels (with different wavelengths) and combine them with up to 8
CWDM channels into one pair of fiber. Dual fiber is used for both the network connection and the
transceiver connections. The two OADMs, shown in Figure 2 and Figure 3, are equipped with a port that
allows you to connect to the booster amplifier and support the following wavelengths:
•EWDM-OADM4—1542.94 nm, 1542.14 nm, 1540.56 nm, 1539.77 nm.
•EWDM-OADM2—1560.61 nm, 1559.79 nm.

DWDM Booster Amplifier (EWDM-OA=)
The DWDM Booster Amplifier (EWDM-OA=) integrates a 10-GB connection over 1-GB CWDM
networks without sacrificing the reach of these networks, and compensates for the power budget gap
between the 10-GB DWDM pluggable transceivers and the low speed 1-GB GBIC/SFP. Dual fiber is
used for both the network and the transciever connections.
The booster amplifier boosts the signal power and therefore the maximum distance for the 10 GB
Ethernet connection.
The booster amplifier modules are equipped with a monitor port that allows you to monitor amplifier
conditions and adjust settings.

Table 6 shows the commands available when you connect to the booster amplifier console port.
CWDM GBIC and CWDM SFP Transceivers
The CWDM GBIC and CWDM SFP transceivers are hot-swappable input/output devices that link your
switching module to the CWDM passive optical system using a pair of single-mode fiber-optic cables.
The two transceiver types have different form factors and use different fiber-optic cable connectors.
Figure 5 shows a CWDM GBIC transceiver which uses an SC connector, and Figure 6 shows a CWDM
SFP transceiver which uses an LC connector.
