Appendix D Technical Specifications
SFP and SFP+ Transceiver Specifications
Table D-45
provides the optical specifications for the Cisco 2-Gbps CWDM SFP transceivers.
Note
•
Parameters are specified over temperature and at end of life unless otherwise noted.
•
When shorted distances of single-mode fiber are used, it is necessary to insert an in-line optical
attenuator in the link to avoid overloading the receiver.
For information about safety, regulatory, and standards compliance, refer to the
