SCALANCE X101-1LD

Transmission speed
The transmission speed of the optical Fast Ethernet port is 100 Mbps.
Transmission mode
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.
Transmission medium
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.
Sender
The light source is an "eye safe" class 1 laser with a wavelength of 1310 nm.
Range
The maximum transmission range (segment length) is 26 km with a signal attenuation of the
fiber-optic cable of ≤ 0.5 dB/km.
Connectors
The cables are connected using BFOC sockets.
GI-PCF
For segment lengths longer than 100 m, you can use GI-PCF cables. Note the information of
the manufacturer.
