The Module conforms to the full duplex implementation
of the Gigabit Ethernet standard, IEEE 802.3z. The ports
use 62.5 µm or 50 µm multimode fiber optic cable with
MT-RJ duplex connectors, and support the segment
lengths specified in IEEE 802.3z, as shown below:
Fiber Bandwidth Segment Lengths Supported
at 850 nm
160 MHz/km 2–220 m (7–722 ft)
200 MHz/km 2–275 m (7–902 ft)
400 MHz/km 2–500 m (7–1805 ft)
500 MHz/km 2–550 m (7–1805 ft)
