1000BASE-ZX SFP
The following table lists the specific optical characteristics for a 1000BASE-ZX
pluggable optic.
The 1000BASE-ZX pluggable optic uses a Low Power Laser (laser class 1/1 according
to FDA/CDRH - 21 CFR 1010 & 1040 / IEC 60825). The 1000BASE-ZX pluggable
optic complies with IEEE 802.3-2002 Clause 38. The following table lists the specific
optical characteristics for a 1000BASE-ZX pluggable optic.
