CGETF1029-105 RJ-45 1000Base-T

100 m (328 ft)*

SC, 1000Base-LX, 1310 TX/1550 RX 
single mode, 20 km (12.4 miles)*

CGETF1029-106 RJ-45 1000Base-T

100 m (328 ft)*

SC, 1000Base-LX, 1550 TX/1310 RX 
single mode, 20 km (12.4 miles)*

The CGETF1029-105 and the CGETF1029-106 are to be
installed in the same network, where one is the local converter
and the other is the remote converter.

CGETF1029-108 RJ-45 1000Base-T

100 m (328 ft)*

SC, 1000Base-LX, 1550 TX/1310 RX 
single mode, 40 km (24.8 miles)*

The CGETF1029-107 and the CGETF1029-108 are to be
installed in the same network, where one is the local converter
and the other is the remote converter.

* Typical maximum cable distance. Actual distance is dependent upon the physical

characteristics of the network installation.  (TX = transmit, RX = receive)

CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the jumper and the 4-position switch and when
installing the CGETF10xx-10x media converter into the PointSystem™ chassis.
Failure to observe this caution could result in damage to, and subsequent failure
of, the media converter.

•

The jumper is located on the media converter circuit board.

•

Use small needle-nosed pliers or a similar device to set the jumper.  

•

Refer to the drawing below for the jumper positions.  

Hardware

The media converter mode is

determined by the 4-position switch
settings (as described on page 3).

Software

The media converter mode is

determined by the most-recently saved,
on-board microprocessor settings.

•

The 4-position switch is
located on the side of the
media converter.  

•

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

1. Twisted-Pair Full/Half Duplex Mode

up

= Full-Duplex on the copper link (see page 6).

down = Half-Duplex on the copper link (see page 6). 

2.

Pause 

up

= Enable Pause (see page 7).

down = Disable Pause.

3.

Link Pass-Through

up

= Enable Link Pass-Through (see page 6).

down = Disable Link Pass-Through.

4.

Fiber Auto-Negotiation

up

= Disable Auto-Negotiation for the fiber link (default setting).

down = Enable Auto-Negotiation for the fiber link.

If the CGETF10xx-10x is connected via fiber to another CGETF10xx-10x, both
media converters must have the fiber Auto-Negotiation setting disabled
(switch 4 = up). Otherwise, the fiber-linked media converters will not link up.

When Fiber Auto-Negotiation is disabled (default setting):
Switches 1, 2 and 3 will function only if Fiber Auto-Negotiation is disabled.
The settings for Twisted-Pair Full/Half Duplex, Pause, and Link Pass-Through
can be set as needed using switches 1, 2 and 3.  

When Fiber Auto-Negotiation is enabled:
Switches 1, 2, and 3 will not function and the media converter adopts the
settings for Twisted-Pair Full/Half Duplex, Pause, and Link Pass-Through from
the media converter at the other end of the fiber cable.  

Fiber Auto-Negotiation allows the fiber interface to detect and subsequently
advertise the support abilities from the remote device. It is supported only
when the fiber is connected to a device with a negotiating port.  The process
is as follows:  
1.

The fiber interface detects the support abilities from the remote partner.

2.

These abilities are passed to the twisted-pair interface and advertised.

3.

Once the twisted-pair interface has a link at the highest common ability,
it passes the result to the fiber interface.

4.

The fiber interfaces then start advertising these abilities. At this point, the
link between the fiber and the negotiating port is complete.
