Technical Specifications
SFP Transceiver Specifications
Table B-31
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 shorter 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
Regulatory Compliance
and Safety Information for the Cisco MDS 9000 Family
