Siemens SCALANCE XB-000 - Scalance Xb004-2

Transmission medium
Data transmission is over multimode 󹪝ber-optic cable (FOC). The wavelength is 1310 nm. The
FO cables are compatible with multimode FO cables with 1300 nm.
Multimode 󹪝ber-optic cables are used with a core of 50 or 62.5 µm; the light source is an LED.
The outer diameter of the FOC is 125 µm.
Range
The maximum transmission range (segment length) with a signal attenuation of the 󹪝ber-optic
cable of ≤ 1 dB/km at 1310 nm is:
• with 62.5/125 µm 󹪝ber multimode SIMATIC NET cable: 4 km
• with 50.0/125 µm 󹪝ber multimode SIMATIC NET cable: 5 km
Connectors
The cables are connected to SC sockets.
4.5.2 SCALANCE XB004-2
Transmission rate
The transmission speed of the optical Fast Ethernet ports is 100 Mbps.
Transmission mode
The transmission mode for 100Base-FX is speci󹪝ed in the IEEE 802.3 standard.
Since the full duplex mode and the transmission rate cannot be modi󹪝ed for optical
transmission, autonegotiation cannot be used.
