Link Pass-Through
The Link Pass-Through feature allows the media converter to monitor both the
fiber and copper RX
(receive)
ports for loss of signal. Refer to the illustration
below. For example, in the event of a loss of an RX signal (1), the media converter
will automatically disable the fiber TX
(transmit)
signal (2), thus, “passing through”
the link loss (3). The far-end device is automatically notified of the link loss (4),
which prevents the loss of valuable data unknowingly transmitted over an invalid
link.
Transparent Link Pass-Through
Transparent Link Pass-Through operates similar to Link Pass-Through with one
exception: the fiber link between the converters remains active. A signal is passed
through to the remote converter, causing it to shutdown the copper link, notifying
the end device of the link failure.
Auto-Negotiation
Auto-Negotiation enables automatic configuration to achieve the best possible
mode of operation over a link between devices. A device with this feature enabled
will broadcast its speed
(10Mbs, 100Mbs, etc.)
and duplex
(half/full)
capabilities to
another device with this feature, then negotiate the best mode of operation
between them—no user intervention required.
Fiber Auto-Negotiation
Fiber Auto-Negotiation allows the fiber interface to detect and then advertise the
support abilities of the remote device. It is supported only when the fiber is
connected to a device with a negotiating port.
Loop Back
This diagnostic feature enables the media converter to loop back the signal from
the RX port to the TX port for testing and troubleshooting purposes. Test signals
from a bit-error test unit can then be inserted into either the copper or fiber link
to test a particular segment.
This type of diagnostic test can only be performed from the local to the remote
device with loop back enabled on the remote device.
SNMP
Note:
SNMP is not supported in the SGETF10xx-1xx converters.
