Scalance X101-1Ld Fo Port - Siemens SCALANCE X101-1 Commissioning Manual

Product Characteristics
4.4 SCALANCE X101-1LD
Note
Devices not supporting autonegotiation must be set to 100 Mbps/ half duplex.
MDI /MDIX Autocrossover Function
The advantage of the MDI /MDIX autocrossover function is that straight-through cables can
be used throughout and crossover Ethernet cables are unnecessary. This prevents
malfunctions resulting from mismatching send and receive wires. This makes installation
much easier for the user.
All media converters of the SCALANCE X-100 series support the MDI / MDIX autocrossover
function.
4.4.5

SCALANCE X101-1LD FO Port

Transmission Speed
The transmission rate of the optical Fast Ethernet port is 100 Mbps.
Transmission Mode
The transmission mode for 100Base-FX is specified in the IEEE 802.3 standard.
Since the full duplex mode and the transmission rate cannot be modified for optical
transmission, autonegotiation cannot be applied.
Transmission Medium
The data are transferred over monomode fiber-optic cable (FOC). The transceiver
wavelength is 1310 nm.
Monomode fiber-optic cables are used with a core diameter of 10 µm. The outer diameter of
the FOC is 125 µm.
Source
The light source is an "eye-safe" Class1 laser with a wavelength of 1310 nm
