Connect the fiber cable
Full duplex (always ON) is on the fiber side only; therefore, the 512-Bit Rule does not
apply. The cable lengths are constrained by the cable requirement.
1. Locate or build IEEE 803.2™ compliant 1000Base-X fiber cable with male,
two-stranded TX to RX connectors installed at both ends.
2. Connect the fiber cable to the M/GE-PSW-xX-01 media converters as follows:
• Connect the male TX cable connector to the female TX port.
• Connect the male RX cable connector to the female RX port.
3. Connect the fiber cable to the other device (another media converter, hub, etc.)
as follows:
• Connect the male TX cable connector to the female RX port.
• Connect the male RX cable connector to the female TX port.

Product features
Congestion reduction
The M/GE-PSW-xX-01 media converters do not forward collision signals or error
packets from one collision domain to another, which results in improvements in
baseline network performance. In addition, the media converter filters packets
destined for local devices, which reduces network congestion.
Auto-Negotiation
The Auto-Negotiation feature is ON permanently for the M/GE-PSW-xX-01 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 /100/1000 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 the second
device then establishes the best operating speed (10/100/100Mbs) at half-duplex.
AutoCross™
The AutoCross feature allows using either straight-through (MDI) or crossover
(MDI-X) copper cables when connecting to 10Base-T or 100Base-TX devices.
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.
Link Pass-Through
The Link Pass-Through feature (illustrated below) allows the media converter to
monitor both the fiber and copper RX (receive) ports 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.

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.
Full-duplex flow control
In a full-duplex network, maximum cable lengths are determined by the type of
cables used—see front cover and cable specifications section.
The 512-Bit Rule does not apply in a full-duplex network.
Note: Full duplex is ON permanently for the fiber port only.
Half-duplex flow control (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the roundtrip delay limitations of each Fast Ethernet collision domain. (A collision domain is
the longest path between any two terminal devices; e.g., a terminal, switch, or
router.)
The 512-Bit Rule determines the maximum length of cable permitted by calculating
the round-trip delay in bit-times (BT) of a particular collision domain. If the result
is less than or equal to 512 BT, the path is good.
For more information on the 512-Bit Rule, see the white paper titled “Collision
Domains” on the Transition Networks website at: www.transition.com
Back pressure
Back pressure is used in half duplex mode. It ensures the retransmission of
incoming packets when a port using half-duplex is temporarily unable to receive
incoming frames.
Flow control
The process of adjusting the flow of data from one device to another ensures that
the receiving device can handle all the incoming data. This is particularly important
where the sending device is capable of transmitting data much faster than the
receiving device can accept it.
Operation—Continued
Product features—continued
Distance extension
The M/GE-PSW-xX-01 media converters can segment one (1) 10Base-T copper
Ethernet, 100Base-T copper fast Ethernet, or 1000Base-T copper Gigabit Ethernet,
and one (1)1000 Base-X fiber Fast Ethernet collision domain:
In a half-duplex Ethernet or Fast Ethernet environment, the M/GE-PSW-xX-01
media converters extend network distances by segmenting collision domains so that
the 512-Bit Rule applies separately to each collision domain.
In a full-duplex Ethernet or Fast Ethernet environment, the M/GE-PSW-xX-01
media converters extend network distances to the physical cable limitations
imposed by the selected twisted-pair copper fiber cables.
Rate conversion
The M/GE-PSW-xX-01 media converters allow the following connections:
• 10Mb/s devices on a 10Base-T legacy copper network to 1000Mb/s devices on
a 1000Base SX/LX Gigabit Ethernet fiber network.
• 100Mb/s devices on a 100Base-T legacy copper network to 1000Mb/s devices
on a 1000Base SX/LX Gigabit Ethernet fiber network.
