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 capable of distances up to 550 meters. (This varies by manufacturer.)
The limit is 850 meters for the optic LC-type connector. The mini-Gigabit transceivers are
compatible with the IEEE 802.3z Gigabit Ethernet standard.
The following table lists 1-Gigabit media types and distances for the different types of
connectors used with the NetScreen-5000 Series systems.
Note: NEBS certification is currently not available on the 5000-M2 management module.
