Single Mode to Multimode Retiming Media
Converter

• Slide-in-Module Media Converter

• Gigabit Ethernet

Transition Networks CFMFF13xx-28x series media
converters extend multimode interfaces over gigabit
Ethernet fiber optic cable. The CFMFF13xx-28x is also
designed to be installed into the Transition Networks
PointSystem™ chassis.

Unlike most gigabit Ethernet media converters, which allow only two media
converters in series, the CFMFF13xx-28x has a retiming/reshaping feature that
makes it possible to connect any number of media converters in series.

Unless otherwise indicated, the distances listed are the typical maximum cable
distance. The actual maximum cable distances are dependent upon the physical
characteristics of the network installation. TX = transmit, RX = receive.

** Minimum Cable Distance: 2 meters

Typical Maximum Cable Distance: 220 meters for 160/500MHz•Km

270 meters for 200/500MHz•Km

CFMFF1329-282 and CFMFF1329-283 are intended to be
installed in the same network where one is the local converter
and the other is the remote converter.

Installation

CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the jumper, the 4-position switch, and when installing
the slide-in-module. Failure to observe this caution could result in damage to,
and subsequent failure of, the media converter.

Set the Hardware/Software Jumper

• The jumper is located on the circuit board.

• Use small needle-nose pliers to set the recessed switches.

Hardware The media converter mode is determined by the

4-position switch settings (see page 4).

Software The media converter mode is determined by the

most-recently saved, on-board microprocessor
settings. (See SNMP on page 6.)

Set the 4-position switch

• The 4-position switch is located on the circuit board.

• Use a small flat-blade screwdriver to set the recessed switches.

Fiber Auto-Negotiation

(Switch 1)

up = Enable fiber Auto-Negotiation for both the single mode and the

multimode ports.

When fiber Auto-Negotiation is enabled:
The pause feature can be set using switches
3 and 4. (See page 4).

down = Disable fiber Auto-Negotiation for both the single mode and the

multimode ports.

When fiber Auto-Negotiation is disabled:
Switches 3 and 4 will not function. The
media converter adopts the pause setting
from the end device at the other end of the
fiber cable.

NOTE: All devices in the network, including the end devices, must have
Auto-Negotiation enabled, or all devices must have Auto-Negotiation
disabled. Otherwise, the devices in the network will not link up.

Link Pass-Through (Switch 2)
up = Enable Link Pass-Through.

down = Disable Link Pass-Through.

The Link Pass-Through feature allows the media
converter to monitor both fiber RX (receive) ports for
loss of signal. In the event of a loss of an RX signal
on one media port, the media converter will
automatically disable the TX (transmit) signal of the
other media port, thus, “passing through” the link loss.

No Pause:

• Pause feature is disabled.

Transmit Only:

• CFMFF13xx-28x can transmit and the
link partner can receive the pause
signal.

Transmit and Receive:

• Both the CFMFF13xx-28x and the
link partner can send and receive the
pause signal.

Receive Only:

• The CFMFF13xx-28x can receive and
the link partner can transmit the
pause signal.

Installation -- Continued

Pause (Switches 3 & 4)
The pause feature can improve network performance by allowing one end of
the link to signal the other to discontinue frame transmission for a set period
of time to relieve buffer congestion.

To properly set the pause feature in the network, the link partner (i.e., the
device to which the CFMFF13xx-28x is linked) must also have comparable
pause switches. If the link partner does not have the pause feature, disable
the pause feature on the CFMFF13xx-28x media converter.

The CFMFF13xx-28x has four pause
options (listed below). To the right of
each option, a drawing shows the switch
settings for the CFMFF13xx-28x and the
link partner.

Install the Fiber Cable

1. Locate or build IEEE 802.3™ compliant fiber cable with male, two­stranded TX to RX connectors installed at both ends.

2. Connect the fiber cables to the CFMFF13xx-28x media converter as
described:

• 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 cables to the other device (another media converter,
hub, etc.) as described:

• Connect the male TX cable connector to the female RX port.

• Connect the male RX cable connector to the female TX port.

Installation -- Continued

Install the CFMFF13xx-28x Slide-in-Module

CAUTION: Slots in the PointSystem™ chassis without a slide-in-module
installed MUST have a protective plate covering the empty slot for Class A
and/or Class B compliance.

The media converter slide-in-modules may be installed in any slot, in any
order. To install the CFMFF13xx-28x slide-in-module:

1. Carefully slide the slide-in-module into the installation slot, aligning the
module’s circuit board with the installation guides.

2. Ensure that the module is firmly seated inside the chassis.

3. Push in and rotate the attached panel fastener screw clockwise to secure
the module to the chassis front.
