Product Description
Lantronix ION x3100 is an SFP-to-SFP fiber repeater with two SFP ports for direct physical connection
back to back. The x3100 performs signal reamplify (1R) signal regeneration. The x3100 also supports:
•CWDM Wavelength transponder, general wavelength to specific wavelength.
•Connections between different types of fiber, such as SM-to-MM.
•Fiber repeater; MM-to-MM or SM-to-SM.
The x3100 can be used in telecom and enterprise applications where 100Mb - 2.5Gb links require fiber
extension or where 100Mb - 2.5Gb links require an interface between two fiber networks.
The x3100 performs a variety of protocol transparent services; it supports virtually any protocol from
100Mbps to 2.5Gbps. The x3100 can inter-connect with another x3100 and can support:
•100Mb (FE/FDDI)
•1.25Gb (GE)
•150Mb (ION x6120 and 6010)
•200Mb (ESCON/SBCON)
•155/622Mb (OC-3/12)
•2488Mb (OC-48)
•2.500Gb (2.5 InfiniBand/PCI-E)
•1.06/2.12 (2/1 GFC)
The x3100 is a “similar rate” to “similar rate” converter with no rate conversions. The x3100 is protocol
independent. Rate configuration is not required. LPT is always enabled.

Application Example
Lantronix ION x3100 is a SFP-to-SFP fiber repeater with two SFP ports for direct physical connection.
The x3100 performs signal reamplify (1R) signal regeneration.The x3100 can be used in telecom and
enterprise applications where 100Mb - 2.5 GB links require fiber extension or where 100Mb - 2.5Gb links
require an interface between two fiber networks.The x3100 performs a variety of protocol transparent
services; it supports virtually any protocol from 100Mbps to 2.5Gbps.
This fiber to fiber converter is a protocol independent device that supports data rates from 100Mbps up to
2.5 Gbps. It provides reliable and cost-effective conversion between single mode and multimode fiber,
while also providing wavelength conversion in CWDM applications. As an SFP based device, this any-
rate to similar-rate converter offers great application flexibility. Supported protocols, fiber connectors, and
transmission distances are determined by the SFP module used on the converter.

Pre-Installation
CAUTION: Observe electrostatic discharge precautions when handling the S3100. Failure to observe this
caution could result in damage or failure of the S3100.
Safety
Before installing the S3100, read these “Safety Cautions” and ensure that the requirements noted are
met. During installation and maintenance, avoid direct exposure to laser beams. Specifically, do not look
into laser ports. Ensure that each SFP port at which laser beams are (or will be) present is occupied by
an SFP that is locked in position. See the related SFP manual for details.
See "Electrical Safety Warnings" on page 18 for Electrical Safety Warnings translated into multiple
languages.
Unpacking
1. Carefully unpack all S3100 contents.
2. Verify receipt of all S3100 components; see “Package Contents” below.
3. Place the S3100 and related materials in the desired install location.
4. Save the S3100 shipping carton and packing materials for future use.

Installation and Setup
General
This section describes how to install the S3100 and the procedures to access and initially set it up via
either a local serial interface (USB) or a remote Ethernet connection (Telnet session or Web interface).
Install the S3100
The S3100 is a standalone module. The following section describes how to install the S3100.
Caution: Failure to observe electrostatic discharge precautions when installing the S3100 could
result in damage or failure of the module.
Figure 2: Installation
1. Locate the S3100 in its final install location.
2. Install SFP Devices in PORT 1 and PORT 2. See “Installing SFP Devices” below.
3. Perform cabling from the S3100.
4. Make the Power Connection. See the “Power Connection” section below.

33581 Rev. C https://www.lantronix.com/ Page 9 of 19
Installing SFP Devices
The S3100 lets you install SFP devices of choice to make a fiber connection. The S3100 has two SFP
ports as shown below.
SFP Optical Transceivers
Lantronix SFP devices are small form factor, hot-pluggable transceivers which allow for a single piece of
network equipment to be connected to a multitude of interfaces, protocols, and transmission media via
the SFP port. All of Transition’s SFPs devices are compliant with the Multi-Sourcing Agreement (MSA)
ensuring interoperability with all other MSA compliant networking devices.
The SFP module used defines the fiber length and type that can be used. Identical SFP modules must be
used at each end of a link for each port on the device.
Figure 3: Port Locations and SFP Installation
To install an SFP device in the S3100:
1. Position the SFP device at either installation slot, with the label facing up.
2. Carefully slide the SFP device into the slot, aligning it with the internal installation guides.
3. Ensure that the SFP device is firmly seated against the internal mating connector.
4. Connect the fiber cable to the fiber port connector of the SFP device.
See the Lantronix SFP webpage web page for the latest information.

Cabling
The x3100 can be used in telecom and enterprise applications where 100Mb - 2.5Gb links require fiber
extension or where 100Mb - 2.5Gb links require an interface between two fiber networks.
The x3100 performs a variety of protocol transparent services; it supports virtually any protocol from
100Mbps to 2.5Gbps.
Figure 4: C3100-to-S3100 Connection
The figure above shows cabling a C3100 to an S3100. The procedure is provided below.
1. Locate a fiber cable with male, two-stranded TX to RX connectors installed at both ends. See “Cable
Specifications” on page 27 for details.
2. Connect the fiber cable to the SFP fiber port (Port 2 labeled SFP) on the S3100:
•Connect the male TX cable connector to the female TX connector.
•Connect the male RX cable connector to the female RX connector.
3. Connect the fiber cables to the SFP fiber port on the other device (C3100):
•Connect the male TX cable connector to the female RX connector.
•Connect the male RX cable connector to the female TX connector.
