Product features
Congestion reduction
The EOF2N media converter do not forward collision signals or error packets from one collision domain to another,
resulting in improvements in baseline network performance. In addition, the media converter filters packets destined for
local devices, which reduces network congestion also.
Auto-Negotiation
The Auto-Negotiation feature is ON permanently for the EOF2N media converters. Auto-Negotiation allows the media
converter to configure itself automatically to achieve the best possible mode of operation over a link. It broadcasts speed
(
10 Mb/s or 100 Mb/s
) and duplex capabilities (
full or half
) 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.
In a scenario where an auto-negotiation device is linked to a non-negotiating device, the negotiating device via parallel
detection recognizes the speed of that second device then establishes the best operating speed (
10Mbs or 100Mbs
) at
half-duplex.
MDI or MDI-X
The EOF2N utilizes either straight-through (MDI) or crossover (MDI-X) copper cables when connecting to 10Base-T or
100Base-TX devices. the EOF2N determines the characteristics of the connection and automatically configures the device
to link up, regardless of the copper cable configuration, MDI or MDI-X.
Link Pass-Through
The Link Pass-Through feature (illustrated below) allows the media converter to monitor both the fiber and copper RX
(receive) port for loss of signal. In the event of an RX signal loss (1), the media converter will automatically disable the 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.

Note:
In the link pass-through devices (EOF2N) both copper and fiber cables must be installed before the LEDs
will light.
