Description
The Transition Networks TN-EOT-xx is an integrated Small-Form Factor Pluggable (SFP) module that enables
traditional Ethernet switch, media converter and other network appliances to connect beyond typical Ethernet
coverage (100 meters). Incorporated with the latest VDSL2 technology, this SFP can be easily adapted to existing
applications with existing 2-wire cable, such as phone line, to avoid the cost of rewiring. It can drastically extend
the Ethernet service on UTP wire with distance up to 3000 meters, and even with the rate of 100Mbps speed up
to 400 meters on a standard Cat 5e 2-wire cable.
The SFP also supports Telco grade noise cancellation techniques like Interleave, high SNR profile, and
retransmission that can effectively eliminate the noise impact to ensure your service/control messages can
securely deliver in a harsh environment.
With long reach coverage, high noise immunity, and compact board size, the Transition Networks TN-EOT-xx is
an ideal upgrade for your Enterprise or Industry applications.

Application Example
TN-EOT-xx SFPs are typically used with Transition Networks’ M/GE-ISW-SFP-01.
Recommended for use with media converters and unmanaged switches.
Does not support use of “Link Pass Thru”. The media converter’s Link Pass Through
(LPT) feature does not work. Supports a maximum MTU of 2048.
Typically for use with unmanaged devices; lock up issues may occur when used with
managed devices.
When the TN-EOT-xx SFP is installed in managed switches, the SFPs maintain synchronization during port state
changes (Disable/Enable). During resets and power cycles, the SFPs maintain sync if the ports were specifically
configured for 1Gbps speed rather than Auto. With some switches, the S3290 in particular, this configuration must
be performed before you insert the SFP.
The TN-EOT-xx SFP doesn’t support SGMII; the port is set to 1Gbps speed by default.

Package Contents
Verify you have received the following items. Contact your
sales representative if any of these items is missing or damaged.
Save the packaging for possible future use.
□One TN-EOT-CO or one TN-EOT-RT SFP
□One RJ-45 to BNC (Pigtail) Adapter, 28008
□One RJ-45 to Terminal Block Adapter, 28009
□One Printed Quick Install Guide
Install Overview
The TN-EOT-xx is an Ethernet Extender in a standard SFP form factor; it provides the ability to leverage the
existing 2-Wire or Coax cable infrastructure to extend the Ethernet service. The TN-EOT-xx can quickly enable
any switch or media converter with a Gigabit SFP slot to connect beyond typical Ethernet distances (100 meters).
Ethernet over Coax
The TN-EOT-xx can extend the Ethernet service on Coax up to 500 meters at 120Mbps bi-directional data rate
(60Mbps downstream and upstream).
Use the RJ-45 to BNC (Pigtail) Adapter, 28008 on both ends for Ethernet over Coax:
Ethernet over 2 Wire with Adapter
The TN-EOT-xx can extend the Ethernet service on 2-wire with distances up to 400 meters at 200Mbps
bi-directional data rate or extend Ethernet on non-UTP 26AWG with distances up to 500 meters at 120Mbps
bi-directional data rate.
Use the RJ-45 to Terminal Block Adapter, 28009 on both ends for Ethernet over 2 Wire:

Transition Networks TN-EOT-xx User Guide
33720 Rev. C https://www.transition.com Page 6 of 13
Ethernet over 2 Wire without Adapter
The TN-EOT-xx can extend the Ethernet service on 2-wire with distances up to 400 meters at 200Mbps
bi-directional data rate or extend Ethernet on non-UTP 26AWG with distances up to 500 meters at 120Mbps
bi-directional data rate.
Connect the twisted pair directly to the SFP through the RJ-45 connector (not using the adapters):
Verified Host Devices
The TN-EOT-xx is verified with the host devices below:
•MGE-ISW-SFP-01
•S3290
•S4224
•SM8TAT2SA
•ION C6120-1040
Note that the TN-EOT-xx can’t work with TN industrial switches in full temperature range (especially in high temp).

Transition Networks TN-EOT-xx User Guide
33720 Rev. C https://www.transition.com Page 7 of 13
Install Procedure
When the TN-EOT-xx SFP is installed in managed switches, the SFPs maintain synchronization during port state
changes (Disable/Enable). During resets and power cycles, the SFPs maintain sync only if the ports were
specifically configured for 1Gbps speed rather than Auto. With some switches, the S3290 in particular, this
configuration must be performed before you insert the SFP.
The TN-EOT-xx doesn’t work on 100Base SFP slot or in SGMII Auto mode; if used with a managed switch, set
speed of SFP slots to Gigabit.
Use the provided adapters as follows:
□Use the RJ-45 to BNC (Pigtail) Adapter, 28008 on both ends for Ethernet over Coax.
□Use the RJ-45 to Terminal Block Adapter, 28009 on both ends for Ethernet over 2 Wire.
1. Insert a TN-EOT-RT into the host device. LED1 lights (orange) as an indicator of RT. Check for physical
connection: LED 2 begins flashing green slowly as soon as you insert the TN-EOT-RT.
2. Insert an Adapter into the TN-EOT-RT. Connect the cabling.
3. Insert a TN-EOT-CO into the host device. Check for physical connection: LED2 (green) begins flashing Green
slowly as soon as you insert the TN-EOT-CO.
4. Insert an Adapter into the TN-EOT-CO. Connect the cabling.
5. Link time takes about 60 seconds. Fast flashing Green LED2 indicates DSL training. LED2 on both SFPs (TN-
EOT-CO and TN-EOT-RT) stays Green when devices link up.

Troubleshooting
Use the steps below to isolate the problem to the TN-EOT-xx and correct the problem.
1. Verify the operating environment matches the specs; see the Specifications section on page 2 above.
2. Check the LEDs; see the Install Procedure on page 5 above.
3. Make sure your application is supported; see Application Example on page 4 above.
4. Make sure the power source meets specs and is operating correctly.
5. For problems with large frames (greater than 4098 bytes) causing the link to drop, try setting the max MTU to
2048 bytes in the application.
6. Make sure the CO side connections and devices are good.
7. Make sure the CPE side connections and devices are good.
8. Record system and device information (see below) before contacting TN Technical Support:
