Chapter1 Product Overview
Ethernet Ports
CWDM SFP transceivers can be used in two ways:
•CWDM transmission, which allows you to send and receive up to 8 laser
wavelengths carrying different signals simultaneously on the same optical
fiber, using an OADM.
•Send ELWL signals, which are capable of transmitting over longer distances
than LWL SFP transceivers
There are eight different “colors” of CWDM SFP transceivers, one for each fixed
wavelength. The fiber optic cables from the CWDM SFP transceivers must be
connected to an Optical Add/Drop Module (OADM), which combines the
wavelengths of the different outgoing signals into one composite send signal, and
separates the received transmissions into the different wavelengths and sends
them to the corresponding CWDM SFP transceiver.
For detailed transceiver specifications, see Appendix C, “Ca ble and Port
Specifications”.
Ethernet Ports
The IPS module supports 1-Gigabit Ethernet ports. For more information about
supported port types, refer to the Cisco MDS 9000 Family Configuration Guide.
