Features
Auto-Negotiation
The M/GE-T-xxx-01 Auto-Negotiation feature is permanently enabled. Auto-Negotiation allows the media converter to
configure itself automatically to achieve the best possible mode of operation over a link. It broadcasts speed (1000
Mb/s) and duplex capabilities (full) to the other device and negotiates the best mode of operation. Auto-Negotiation
allows quick and easy installation because the optimal link is established automatically.
Auto MDI / MDI-X
The AutoCross feature allows using either straight-through (MDI) or crossover (MDI-X) copper cables. AutoCross
determines the characteristics of the connection and automatically configures the device to link up, regardless of the
copper cable configuration, MDI or MDI-X
.
Automatic Link Restoration
The media converter will automatically re-establish the link when connected to a switch if the link is lost, even with
Auto-Negotiation and Link Pass-through (both directions) enabled.
Fiber Link Pass Through (Fiber port only)
Link Pass Through is a troubleshooting feature that prevents media converters from isolating link failures and it allows
end devices to be notified in the event of a loss of link. Link Pass Through provides the media converter with the ability
to monitor both the fiber and the copper RX ports for a loss of signal. If a loss of RX signal occurs on one media port, the
converter will automatically disable the TX signal on the other port. By shutting down the fiber TX port, the link failure is
“passed through” to the remote converter
and device. The end device automatically notified of link loss, which prevents
loss of valuable data unknowingly transmitted over an invalid link.
