The RJ-45 twisted-pair ports are compatible with the IEEE 802.3 Type 10/100 Base-T
standard.
The mini-Gigabit transceivers used in NetScreen-5000 Series modules are Shortwave or
SX type, so they are good for up to 550 meters. (This varies by manufacturer.) The limit is
850 for the optic LC-type connector. The mini-Gigabit transceivers are compatible with
the IEEE 802.3z Gigabit Ethernet standard.
The following table lists media types and distances for the different types of connectors
used in the NetScreen-5000 Series.
Note: NEBS certification is currently not available on the 5000-M2 management module.
