3 Switch 4400 1000BASE-LX Module
(3C17223) provides your SuperStack 3 Switch 4400 with
one 1300 nm Gigabit Ethernet fiber optic port.
The Module conforms to the full duplex implementation
of the Gigabit Ethernet standard, IEEE 802.3z, and
provides a 1000 Mbps connection to another
1000BASE-LX device. This port uses 62.5 µm or 50 µm
multimode or 8–10 µm single mode fiber optic cable with
MT-RJ duplex connectors and supports the segment
lengths specified in IEEE 802.3z, as shown below:
