Introduction
The Media Converter enables you to extend the distance of your 10/100BaseTX Ethernet network up to 2 kilometers for multi-mode fiber or up to 30 kilometers for single-mode fiber. SC, ST and MT-RJ optical multimode fiber connectors are available.
This range of media converters also includes a WDM ( Wavelength Division Multiplexing ) Converter. This has exactly the same functionality as the standard converters but the WDM technology that combines the transmit (TX) and receive (RX) lines onto a single fiber, which reduces cabling cost.
A pair of WDM converters ( wavelength 1310 and 1550 nm ) should be installed at either end of the single fiber cable.

Ports
n RJ-45 Port. This Ethernet RJ-45 supports both shielded
and unshielded cabling systems. The port either auto-negotiates the 10/100Mbit/s network speed or can be forced by DIP switch 1 into a 100Mbit/s full-duplex mode. In addition, the port uses auto MDI/MDIX detection which eliminates the need for cross-over cables when connecting to LAN switches or workstations.
n Fiber Port. This port is for the 100 Base-FX connection to
the distant media converter, NIC card or Ethernet switch. The port operates in either full duplex or half duplex modes depending on the setting of DIP switch 2.

Rear Panel
The rear panel contains a power socket. This power socket accepts DC 9V voltage and minimum 0.7A supplied current.
Installation
Copper and Fiber Cabling Guidelines
1. The RJ-45 port can be connected to unshielded twisted pair (UTP) or shielded twisted pair (STP) cabling systems. The cable must comply with the IEEE 802.3u 100Base TX standard for Category 5. The cable between the converter and the link partner device (switch, hub, workstation, etc.) must be less than 100 meters (328 ft.) long.
2. The fiber link on the multi-mode converter must use either 50 or
62.5/125 micron multi-mode fiber cable. You can link two converter devices over a distance of up to 2 kilometres.
3. The fiber link on the single-mode converter must use 8/125 or 9/125 micron single-mode fiber cable. You can link two converters over a distance of up to 30 kilometers in full duplex operation (DIP-Switch 2 = off). If the converter is operated in the half-duplex mode (DIP-Switch 2 = on), the recommended maximum distance is reduced to 412 metres (1,352 ft.)
Installing Media Converters into the Chassis
Follow the steps below to install converters into the 19” rack-mountable chassis (part number 1-1591032-1).
1. Remove the blank plate from the chassis using a screwdriver. Put the blank plate aside.
2. Open the rackmount bracket kit which contains two rackmount brackets with thumbscrews and four securing screws.
3. Attach a rackmount bracket on both sides of the media converter using a screwdriver.

Tyco Electronics Page 6
Fast Ethernet Media Converter
1. Select the appropriate length Cat. 5/5e twisted pair cable, then connect one end of the cable to the RJ-45 connector on the media converter and the other end of twisted pair cable to the RJ-45 connector on the partner 10/100Mbit/s Ethernet partner device.
2. Connect one end of a fiber cable to the ST/SC/MT-RJ connector on the converter and the other end of the fiber cable to the ST/SC/MT-RJ connector on the remote 100 Base-FX device, typically another media converter.
3. Apply the DIP-Switch settings as detailed on page 8.
4. Attach the power adapter DC jack to the converter and verify that the Power (PWR) LED on the front panel lights up.
5. Verify that UTP LK/ACT LEDs light up when the UTP cable connection is correct, and Fiber LK/ACT LED is either green to show presence of a valid fiber link or blinks to indicate traffic activity.

DIP-Switch Settings
The configuration switch is used to set the line speed of the UTP port, the operation mode for the Fiber port, Link Loss Forwarding and the setting of “pure” or “switching” operation of the converter. The default switch setting is UTP = Auto-negotiate, Fiber = Full Duplex, LLF =disable and converter in switched mode.

Figure 5 – Default DIP Switch Settings
UTP Auto-negotiation
With DIP-switch 1 in the OFF (up) position, the converter will try to auto-negotiate with its partner. If the partner device does not support auto-negotiation, then the converter will detect either 100Mbit/s or 10Mbit/s and operate in the half duplex mode. (Default setting
).
100M Full-duplex
With DIP-switch 1 in the ON (down) position, the converter forces the UTP port to 100Mbit/s full duplex operation.
Fiber Full-duplex
With DIP-switch 2 in the OFF (up) position, the fiber port will be configured in 100Mbit/s full-duplex mode (Default setting
).
Fiber Half-duplex
With DIP-switch 2 in the ON (down) position, the fiber port is configured to 100Mbit/s half-duplex mode .
Tyco Electronics Page 8
Fast Ethernet Media Converter
Link Loss Forwarding Disable
With DIP-switch 3 in the OFF (up) position, the converter will not operate in the Link Loss Forwarding mode. In this case, fault events are not signaled across the link or to the distant unit. (Default setting
).
Link Loss Forwarding Enable
With DIP-switch 3 in the ON (down) position, the converter will enable the Link Loss Forwarding function which can be used to extend the fault status over the link to the distant unit.
Switch converter mode
With DIP-switch 4 in the OFF (up) position the converter will operate in store and forward switch converter mode. In this mode any illegal frames will be rejected by the converter (Default setting
).
Pure converter mode
With DIP-switch 4 in the ON (down) position the converter will operate in “pure “ converter mode. In this position the converter will transmit the data as soon as it is received and so the traffic will flow quicker than when in switch converter mode. For such applications the converter should operate in 100M operation.
Notes:-
§ After changing the DIP-switch setting, the unit needs to be reset by power-cycling before the switch changes can take effect.
Tyco Electronics Page 9
Fast Ethernet Media Converter
Link Loss Forwarding (LLF)
It is common in networking for resilient secondary routes to be adopted so if the main route is broken the second route becomes active and automatically starts to pass traffic third party equipment uses spanning tree to implement this resilient function. It is important therefore that accurate diagnosis of a route failure by the connected network equipment takes place. To support this signaling, link loss forwarding is provided by the converter. If DIP – switch 3 is set to ON then LLF is enabled. When enabled disconnecting the fiber then the RJ45 port will lose link status. When disconnecting the copper JR45 port the optical port will lose link status.
Maximum Frame Size
The maximum frame size that the 10/100 media converter can support when in “switch” converter mode is 1589 bytes including CRC and tagged VLAN extension. All Packets greater than 1589 bytes are discarded and so will not pass across the link. When in “pure” converter mode packets will not be rejected regardless of size.

Trouble Shooting
Power
1. Only use the correct AC/DC power adapter (DC 9v, 0.7 Amp with the positive to the center pin of the power connector). Do not use a power adapter with DC output voltage higher than 9V, or with the wrong polarity as this will damage the converter.
Fiber Link
1. Select the proper fiber cable for your network. The multi-mode converter must use multi-mode fiber cable and the single-mode converter must use single-mode fiber cable. See page 5 for the supported cable types and installation settings.
2. Ensure that the optical loss budget of the fiber link is within the limits specified on page 14. Note that optical patch cables and other joints and splices can introduce additional optical losses that reduce the available working distance of the fiber link.
Data Problems
1. Ensure that the Ethernet partner device (switch, router, NIC etc) connected to the UTP port of the converter is set for auto-negotiation. If this Ethernet partner device does not support auto-negotiation, then you need to program that device to operate at 100Mbit/s half duplex or 10Mbit/s half duplex. This is because the media converter and the Ethernet device will not be able to correctly negotiate and will then revert to the lower level of half-duplex operation.
This issue is common to all auto-negotiating Ethernet units and symptoms of failed negotiation include data errors and fragmented packets.
2. Auto-negotiation can take up to 30 seconds to achieve, depending on the connected partner device.
3. Check the configuration of the front panel DIP switches. The default setting for the fiber link is Full Duplex and the default setting for the UTP port is Auto-Negotiate. Link Loss Forwarding is disabled by default. See page 8 for DIP switch settings.
Tyco Electronics Page 12

4. Ensure that the media converter is reset by removing power after either of the DIP switch settings have been changed.

Optical Fiber Specifications
The standard converters operate at the 1310nm optical wavelength for both the multimode and singlemode media converters. The WDM converters operate at the 1310nm and 1550nm optical wave length simultaneously . The fiber size used for multimode links is 50/125 or 62/125 micron. The fiber size used for singlemode links is 8/125 or 9/125 micron.
The maximum distance between any two fiber optic devices is determined by a number of factors including optical link loss, the type and number of patch cords and joints in the link, the launch power of the transmitter and the sensitivity of the receiver. These variables make calculating the maximum working distance between two converters quite difficult and so it is best to design networks using optical loss budgets rather than using just working distance.
