1000BASE-SX SFP
The characteristics of the 1000BASE-SX SFP are summarized in the table below.
The 1000BASE-SX pluggable optic (850 nm short haul, multi-mode) uses a Low
Power Laser (laser class 1/1 according to FDA/CDRH - 21 CFR 1010 & 1040 / IEC
60825). The 1000BASE-SX pluggable optic complies with IEEE 802.3-2000 Clause
38. The following table describes the various operating ranges for the 1000BASE-SX
pluggable optic over each optical fiber type.
Fiber Type Modal Bandwidth @ 850 nm (min.
