Cisco CWDM OADMs
Technical Specifications for Cisco CWDM OADMs
The Cisco CWDM OADMs are passive devices that provide the capability to multiplex and demultiplex, or add and
drop wavelengths from multiple fibers onto one fiber. The OADM connectors are interfaced with color-matching
Cisco CWDM SFPs on the equipment side. All modules are the same size. The Cisco CWDM chassis enables rack
mounting for up to two Cisco CWDM OADMs in a single rack unit.
The Cisco MDS 9000 family offers two CWDM OADMs and a multiplexer and demultiplexer:
●
Cisco Dual Fiber 4-Channel OADMs (part numbers DS-CWDMOADM4A= and DS-CWDMOADM4B=):
This device allows you to add and drop four channels (with different wavelengths) onto one direction of an
optical ring. The other wavelengths are passed through the OADM. Dual fiber is used for both network and
SFP connections. The four wavelengths are set to 1470, 1490, 1510, and 1530 nm for DS-CWDMOADM4A=,
and 1550, 1570, 1590, and 1610 nm for DS-CWDMOADM4B=.
●
Cisco Dual Fiber 8-Channel Multiplexer/Demultiplexer (DS-CWDM-MUX8A=): This device allows you to
multiplex and demultiplex eight separate channels onto one pair of fiber. Dual fiber is used for both network
and SFP connections. The eight wavelengths are set to 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610
nm.
Tables 35 and 36 provide comparisons of the OADM types.

Environmental Conditions and Power Requirements
The operating temperature range is 23 to 131°F (–5 and 55°C), and the storage temperature range is –40 to 185°F
(–40 to 85°C).
The Cisco CWDM OADMs and the Cisco CWDM chassis are passive components that do not require power.
Dimensions and Weight
All the Cisco CWDM OADMs have the same dimensions: W x D x H: 21.2 x 3.0 x 26.5 cm. Two of these modules fit
into one Cisco CWDM chassis. The Cisco CWDM chassis is one-rack-unit (1RU) in height and fits in a standard 19-
inch rack.
