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.
