Note
When shorter distances of single-mode fiber are used, it might be necessary to insert an inline optical
attenuator in the link to avoid overloading the receiver.
Cisco DWDM SFP Transceivers
Main features of the Cisco DWDM SFP include:
•
Support for International Telecommunication Union (ITU) 100-GHz wavelength grid
•
Match for wavelength plan of Cisco 100-GHz ONS product family
•
Fixed-wavelength SFP, with 40 different SFP models
•
Hot-swappable input/output device that plugs into Gigabit Ethernet SFP ports or slots of a Cisco
switch or router, linking the port with the network
