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-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.

Table A‐3 provides you with the input/output specifications for each version of XFP.

Table A-3 XFP Fiber-Optic Specifications

		Extinction	Received
XFP Module	Output Power	Ratio	Sensitivity	Link Budget
10GBASE-LR-XFP	<0.5 dBm	>4 dB	-10.28 dBm	0 to 9.4 dB
10GBASE-ER-XFP	<4.0 dBm	>3 dB	-10.3 dBm	5 to 11 dB
10GBASE-SR-XFP	<-1 dBm	>3 dB	-11.1 dBm	7.3 dB

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-4 Recommended Cable Types and Specifications

XFP Module	Type	Max. Length	Connector
10GBASE-LR-XFP	SMF	10 km (6.21 mi)	LC
10GBASE-ER-XFP1	SMF	40 km (24.85 mi)	LC
10GBASE-SR-XFP	62.5 um MMF 200Mhz/km	33 m (108 ft)	LC
	50 um MMF 400Mhz/km	66 m (217 ft)	LC
	50 um MMF 2000Mhz/km	300 m (884 ft)	LC

1. The 10GBASE-ER-XFP requires a minimum of 5 dB attenuation or a cable length of about 10 km.
