iConverter® CWDM/AD
1 Channel Single-Fiber Add/Drop Multiplexer
USER MANUAL
Product Overview
iConverter 1-Channel Single-Fiber CWDM/AD modules are Course Wave Division
Multiplexing (CWDM) Optical Add and Drop Multiplexers (OADM). The CWDM/AD
modules add (multiplex) and drop (de-multiplex) one channel on one or both
directions of a CWDM single-ber common link. Nine standard models of the
1-Channel Single-Fiber CWDM/AD modules are available.
The Single-Fiber CWDM/AD modules support dual ber Channel Ports and single-
ber Common Port connections. Each ber strand on the Channel Port supports a
different wavelength, one wavelength for transmit (TX) and a different wavelength
for receive (RX).

Figure 2: 1-Channel Add/Drop MUX/DEMUX
Figure 2 illustrates the operation of the Add/Drop MUX/DEMUX. The illustration
shows the Common Ports (COM-L and COM-R) as bidirectional single-ber
connections. The Channel Ports (CH1-L and CH1-R) are composed of two different
wavelengths creating a dual ber connection.
As an example, the illustration shows the Channel Port wavelength conguration
for model 8878-47. The wavelength for CH1-L RX is 1490 and a TX of 1470, and
CH1-R RX of 1470 and a TX of 1490.
Port Denitions
Channel Port (Left and Right)
The Channel Ports transmit and receive signals using two specific CWDM
wavelengths based on the CWDM/AD model. The Channel Ports are multiplexed
and demultiplexed from the Common Port. As shown in Figure 2, each Channel
Port on the CWDM/AD module has a Left (CH1-L) and Right (CH1-R) port. Data
transmitted and received by Channel Port Left is aggregated on Common Port Left
(COM-L) and data transmitted and received by Channel Port Right (COM-R) is
aggregated on Common Port Right.
When connecting external dual ber transceivers to the Channel Port, select an
optical transceiver that matches the receive (RX) wavelength of the specic Channel
Port. Since the Channel Port uses two different wavelengths over dual ber, the
receiver of the external dual ber transceiver must have the capability to detect
the transmit wavelength of the Channel Port. Typically, the receiver of a dual ber
transceiver has an operating center wavelength of 1260nm to 1610nm. Verify the
external transceiver’s optical parameters before using.
Common Port (Left and Right)
The aggregated wavelengths from the Channel Ports are transmitted and received
over the single-ber Common Port. As shown in Figure 2, there are Left and Right
Common Ports on the CWDM/AD module. Common Port Left (COM-L) and Common
Port Right (COM-R) are internally connected to pass through all wavelengths not
dropped or added by the specic CWDM/AD model Only the specic wavelengths

of the model selected will be dropped to the appropriate Channel Port. Common
Port Left drops and adds wavelength trafc from Channel Port Left and Common
Port Right drops and adds wavelength trafc from Channel Port Right.
Installation
1. Carefully slide the module into an open slot in an iConverter chassis. Align
the module with the installation guides and ensure that the module is rmly
seated against the backplane. Secure the module by fastening the front panel
thumbscrew (push in and turn clockwise to tighten) to the chassis front. The
CWDM/AD module requires no external power, however, if management is
required, the module must be installed in an iConverter powered chassis with a
Network Management Module (NMM2 Model 8000N-0) or a M2 series or higher
module (such as the iConverter 10/100M2, GM3 or GM4).
2. Connect a single-mode, dual ber duplex LC cable between the Channel Port
of the CWDM/AD module and the attached device. It is important to ensure
that the wavelength of the CWDM/AD matches the wavelength of the attached
device. Connect both Channel Ports in this manner. Ensure that the transmit
(Tx) is attached to the receive side of the device at the other end, and the
receive (Rx) is attached to the transmit side.
3. Connect a single-mode, single-ber simplex LC cable between the Common
Ports on the CWDM/AD modules (this connection may be made through ber
patch panels since the modules may not be co-located) or CWDM/X module.
Make sure the Left/Right designation is followed.
NOTE: For proper installation, a network diagram indicating port designations is
recommended.
NOTE: The iConverter CWDM/AD modules cannot be installed in slots 4, 8, 12 and
16 of a 19-Module Chassis or in the top slot of a 2-Module Chassis or in a 1-Module
Redundant Power Chassis.
Design Considerations
Attenuation (signal loss) of less than 1.9dB will be realized through each port on
the module (see the CWDM/AD Data Sheet for exact attenuation specications for
model used). Detailed calculations should be performed for each ber optic link in
the network to ensure the CWDM transceiver has sufcient transmit power.
When calculating optical loss, ensure that the total attenuation, plus a safety factor
(typically 3dB), does not exceed the optical power budget of the transceiver. The
optical power budget is the difference between the transmitter optical output power
and the receiver’s optical sensitivity. The transmitter optical output power and
receiver optical sensitivity values can be obtained from the manufacturers of the
respective equipment.
