Differences sfp-10g-lr-s VS sfp-10g-lr

Time:2013-04-11 Views:3060
What differences are between sfp-10g-lr-s and sfp-10g-lr?
Some people say the difference is operating temperature range. The truth is both operating temperature same.
Commercial temperature range (COM): 0 to 70°C (32 to 158°F)
Storage temperature range: -40 to 85°C (-40 to 185°F)
The truth is from Cisco Website.
