Maximum distance of fiber optic connections

The maximum distance of fiber optic connections between 2 devices depends on various

influencing factors. This includes, for example, the specification of the fiber (e.g.

50/125 μm, 62.5/125 μm, etc.), or the attenuation of other components in the fiber optic

cable plant such as couplers or patch panels.

However, the maximum distance can be estimated on the basis of the output power of

the transmitting interface (TX) or the sensitivity of the receiving interface (RX). A model

calculation can be found in chapter 10.2.

The specification of the transmitter’s output power and the receiver’s sensitivity of the

fiber optic components installed in the device can be found in chapter 10 “Technical data”

under “ibaNet interface”.

32Mbit Flex mode

32Mbit Flex is the preferred mode for data acquisition applications with ibaPDA. ibaLink

io-embedded has to be configured at least once, see chapter 7 “Software”. The ibaPDA

application reads the configuration and displays the configured signals. The user can

select the signals to be measured and adjust the cycle time. The cycle time can be faster

for small amounts of data, up to 10 μs with 17 Bytes. The maximum amount of data is

4060 Bytes at 1.4 ms. The data format and size can freely be set. The application can

use the complete RX and TX buffer (4060 Bytes).

32Mbit Flex requires a bidirectional FO connection to a card of the ibaFOB-D type for

communication. With 32Mbit Flex, it is possible to connect up to 15 devices in a ring

topology.
