Description
Unallocated margin in link power
budget (a wavelength of 830 nm
is used to calculate the values)
1000BASE-LX SFP
The following table lists the specific optical characteristics for a 1000BASE-LX
pluggable optic.
The 1000BASE-LX pluggable optic uses a Low Power Laser (laser class 1/1 according
to FDA/CDRH - 21 CFR 1010 & 1040 / IEC 60825). The 1000BASE-LX pluggable
optic complies with IEEE 802.3-2000 Clause 38. The table below describes the various
operating ranges for the 1000BASE-LX pluggable optic over each optical fiber type.
