Table B-9
lists the fiber loss budgets for the 1-GB SFP transceivers.
Table B-10
lists the physical and environmental specifications for the 1-GB SFP transceivers.
Note
You can use any combination of SFP modules that your Cisco device supports. The only restrictions are
that each SFP port must match the wavelength specifications on the other end of the cable and that the
cable must not exceed the stipulated cable length for reliable communications.
