Component Type Maximum
Power (W)
10/100/1000Base Ethernet Optic (and Copper-RJ45) Module SFP 1 W
OC-3/STM-1 SONET/SDH Optic (and Electrical) Module SFP 1 W
10GBase (and low-power DWDM) Ethernet Optic Module SFP+ 1.5 W
10GBase (DWDM) high-power Ethernet Optic Module SFP+ 2 W
10GBase Ethernet Optic Module XFP 3.5 W
Note: The ambient temperature outside the 7705 SAR will influence the SFP case
temperature, depending on which chassis the SFP is installed in. The maximum system inlet
ambient temperature to SFP temperature rise is as follows:
• up to 10
°
C for the 7705 SAR-18, 7705 SAR-8 Shelf V2, 7705 SAR-F, and 7705 SAR-X
• up to 15
°
C for the 7705 SAR-A, 7705 SAR-M, 7705 SAR-W, and 7705 SAR-Wx
• up to 20
°
C for the 7705 SAR-8, 7705 SAR-H, and 7705 SAR-Hc
Ensure that the SFP to be installed supports an operating temperature range that
accommodates the expected temperature rise inside the chassis.
