Supported XFP Transceiver Interface Options
At the time this manual was printed, three 10GBASE XFP modules are available. The
optional XFPs are hot swappable and are IEEE 802.ae compliant.
Table A‐2 lists the XFPs and the type of fiber‐optic connection and 10GBASE standard that
each one supports.
Table A‐3 provides you with the input/output specifications for each version of XFP.
Table A‐4 provides you with the necessary information to make decisions concerning the
cable type, maximum length, and connector type according to each XFP module.
Table A-2 Supported XFP Transceivers
XFP Specification
10GBASE-SR-XFP Provides one LC fiber-optic multimode port that is compliant with the
10GBASE-L standard.
10GBASE-LR-XFP Provides one LC fiber-optic single-mode port that is compliant with the
10GBASE-LR standard.
10GBASE-ER-XFP Provides one LC fiber-optic single-mode port that is compliant with the
10GBASE-ER standard.
