Link Through
Note: Link Through function only takes effect when switch 4 is set to
activated.
This bridge supports Link Through (LT) function in TX/FX converter
application. The link status on one port is propagated to the other port to
notice the remote nodes. If TP port is unplugged, this converter stops
transmission on fiber port. This causes the remote fiber node link to fail.
The LEDs show a failure on both, TP and fiber ports. If fiber link fails, this
converter restarts autonegotiation on TP port but always stays in the link
failure state. This causes the remote TP node link to fail. The LEDs also
show the link failure on both, TP and fiber port (see fig. 5 and fig. 6).
Warning: The Link Through function works only when these bridges are
used in a pair and both have the link through activated. Furthermore both
link through bridges should be supplied by the same manufacturer.
Connections coming from old link through bridges or bridges without link
through will cease the link through function.
LED displays
The bridge has 5 integrated LEDs giving status information which can be
used for error diagnostics. Please refer to fig. 8 for a description of these
LEDs.
Power supply
The bridge is supplied with an external AC power supply. The bridge
requires 5 V DC input. Because of warranty reasons it is only allowed to
use the original power supply.
The DC jack’s central post is 2.5 mm wide (see fig.7).
Optional the bridge can be powered by an USB port. When selected the
USB power mode a special USB cable is included at delivery. With this
cable the bridge can be connected to a PC with USB port or a USB hub.

8. Safety notes
DANGER! - Optical components may radiate laser light.
WARNING: Infrared radiation as used for data transmission within the
fiber optic area which, although invisible to the human eye, can
nevertheless cause damage.
To avoid damage to the eyes:
•
Never look straight into the output of fiber optic components –
danger of blinding!
•
Cover all unused optical connections with caps.
•
Commission the transmission link only after completing all
connections.
The active laser components used with this product comply with the
provisions of Laser Class 1.
DANGER! – Conductive parts from Power- and Telecommunication
networks can transport dangerous voltage.
To avoid electrical shocks, all installations must be confirm to the
required safety standards if the region where they are used.
