Transmission speed
The transmission speed of the optical Fast Ethernet port is 100 Mbps.
The transmission mode for 100Base-LX is specified in the IEEE 802.3 standard.
Since the full duplex mode and the transmission speed cannot be modified for optical
transmission, autonegotiation cannot be used.
Data transmission is over single-mode fiber-optic cable (FO cable). The transceiver
wavelength is 1310 nm.
Single-mode fiber-optic cable with a core diameter of 10 µm is used.
The outer diameter of the FO cable is 125 µm.
The light source is an "eye safe" class 1 laser with a wavelength of 1310 nm.
The maximum transmission range (segment length) is 26 km with a signal attenuation of the
fiber-optic cable of ≤ 0.5 dB/km.
The cables are connected using BFOC sockets.
For segment lengths longer than 100 m, you can use GI-PCF cables. Note the information of
the manufacturer.
