The SuperStack 3 Switch 4300 1000BASE-LX Module
(3C17141) provides your SuperStack 3 Switch 4300 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. The port uses 62.5 m or 50 m
multimode or 8-10 m single mode fiber optic cable with
MT-RJ duplex connectors and supports the segment
lengths specified in IEEE 802.3z, as shown below:
