ONNECTORS

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.
