Transmission mode
Transmission with 1000Base-LX is defined in the IEEE 802.3z standard and is specified as
1000 Mbps transmission rate and full duplex.
Transmission medium
Data is transmitted over single mode FOC. The wavelength is 1310 nm or 1550 nm.
The core diameter of the single mode FOC is 9 or 10 µm; the light source is a laser diode. To
transmit a signal, only one mode is used greatly reducing dispersion. As a result, the
maximum range of single mode FOC is greater than that of multimode FOC.
Transmission range
The maximum transmission range (segment length) is 120 km for single mode FOC.
Connectors
SC duplex female connectors are used.
