Dimensions
●
Dimensions (L x W x H): 71 x 18.5 x 8.5 mm. Cisco XFPs typically weigh less than 300 grams.
●
Environmental conditions and power requirements:
◦
Operating temperature range: 32 to 158°F (0 to 70°C).
◦
Storage temperature range: -40 to 185°F (-40 to 85°C).
◦
The maximum power consumption per Cisco XFP module is 3.5W.
