Transmission speed

The transmission speed of the optical Fast Ethernet ports 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 selected.

Transmission medium

Data transmission is over multimode fiber-optic cable (FO cable). The wavelength is 1310

nm.
Multimode fiber-optic cables are used with a core of 50 or 62.5 µm; the light source is an

LED.
The outer diameter of the FO cable is 125 µm.

Transmission range

The maximum transmission range (segment length) is up to 5 km depending on the cable

type.

Connectors

The cables are connected over BFOC sockets.
