1. Introduction

The KGC-261-DP series are Gigabit Ethernet media converters which provide the following features:

Data Conversion between different Media types and Speed

The media converter supports the following conversions:

 1000Mbps (1000BASE-T) copper to/from 1000Mbps (1000BASE-X) fiber
 100Mbps (100BASE-TX) copper to/from 1000Mbps (1000BASE-X) fiber
 10Mbps (10BASE-T) copper to/from 1000Mbps (1000BASE-X) fiber
 1000Mbps (1000BASE-T) copper to/from 100Mbps (100BASE-FX) fiber
 100Mbps (100BASE-TX) copper to/from 100Mbps (100BASE-FX) fiber
 10Mbps (10BASE-T) copper to/from 100Mbps (100BASE-FX) fiber

Dual-speed SFP Fiber Connectivity

The SFP port can be installed with different optional SFP optical fiber transceiver to support multimode or
single mode fiber for short reach up to long reach distance. The SFP can support both 1000BASE-X and
100BASE-FX fiber connection. This feature extends a wider application range with this device.

Link Fault Pass-Through

This important feature of a media converter can force the link to shut down as soon as it notices that the other
link has failed. It allows a link partner on one cable segment can notice a link fault occurred on the other
segment and give application a chance to react.

3. Making LAN Connections

3.1 10/100/1000 TP Copper Port

The 10/100/1000 TP copper port supports the following connection types and distances:

Network Cables

10BASE-T: 2-pair UTP Cat. 3, 4, 5 , EIA/TIA-568B 100-ohm
100BASE-TX: 2-pair UTP Cat. 5, EIA/TIA-568B 100-ohm
1000BASE-T: 4-pair UTP Cat. 5 or higher (Cat.5e is recommended), EIA/TIA-568B 100-ohm
Link distance: Up to 100 meters for all above

Auto MDI/MDI-X Function

This function allows the port to auto-detect the twisted-pair signals and adapts itself to form a valid MDI to
MDI-X connection with the remote connected device automatically. No matter a straight through cable or
crossover cable are connected, the ports can sense the receiving pair automatically and configure themselves to
match the rule for MDI to MDI-X connection. It simplifies the cable installation.

Auto-negotiation Function

The port is featured with auto-negotiation function and full capability to support connection to any Ethernet
devices. The port performs a negotiation process for the speed and duplex configuration with the connected
device automatically when each time a link is being established. If the connected device is also
auto-negotiation capable, both link partners will come out the best configuration after negotiation process. If
the connected device is incapable in auto-negotiation, the port will sense the speed and use half duplex for the
connection.

3.2 Making Fiber Connection

The SFP slot (FX port) must be installed with an SFP fiber transceiver for making fiber connection. Your
device may come with an SFP transceiver pre-installed when it was shipped.

Installing SFP Fiber Transceiver

To install an SFP fiber transceiver into SFP slot, the steps are:

1. Turn off the power to the device unit.

2. Insert the SFP fiber transceiver into the SFP slot. Normally, a bail is provided for every SFP transceiver.

Hold the bail and make insertion.

3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.

Dual Speed Support

The SFP slot supports 1000BASE-X based SFP fiber transceivers and 100BASE-FX based SFP fiber
transceivers. Refer to Section 2.7 DIP SW Configuration for FX port operating mode setting.

Connecting Fiber Cables

LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX connector

-26-

before making cable connection. The following figure illustrates a connection example between two fiber
ports:

Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.

Network Cables

Multimode (MMF) - 50/125, 62.5/125
Single mode (SMF) - 9/125

3.3 Making PoE Connection

The device is equipped with PoE PSE function, which can supply power to a remote Ethernet device together
with LAN data via TP port over Cat.5 cable. Above figure is a standard PoE connection example. By

4. Functions

This chapter describes some advanced functions provided by the media converter.

4.1 Converter Function

Media Conversion

The device supports the following data conversions between fiber cable and twisted-pair Cat.5 (copper) cable:

The data rate on twisted-pair segment depends on the link speed finally established with the link partner.

4.2 Link Fault Pass Through Function

When the Link Fault Pass Through (LFPT) function is enabled and the media converter detects a link fault on
one port segment, it will force the other port segment link down. It looks like that a link fault is passed from
one port to the other.

The following example illustrates a link fault occurs on the fiber cable (any one cable in a duplex fiber
connection). The link fault is forwarded to both copper link partners finally by LFPT operation of two media
converters.

Both Ethernet devices will also detect a link fault on each Cat.5 connection, although the real fault occurs on
the fiber connection exactly.

-31-

The following example illustrates a real link fault occurs on one Cat.5 and the link fault is passed to the other
Cat.5 over two converters and the fiber cable by LFPT operation. Finally, the other link partner also detects a
link fault.

Advantage

The function allows two remote link partners of the media converters detect the link fault finally no matter
where the exact fault occurs. It allows the upper application takes necessary action in case a real link fault
occurs in any cable segment.

Methods to enable the function

The LFPT function can be enabled by:
Software setting: Web management ->
Configuration -> System -> [Link fault pass through]

4.3 802.1Q Control Function

802.1Q Control function allows perform 802.1Q VLAN related operation to the packets passing through the

media converter according packet contents as follows:

[Ingress Drop] setting

The setting is the first filtering mechanism to filter incoming packets based on frame types. The options are:

Disable - disable port ingress drop and admit all packet types
Drop Untag - drop all untagged frames
Drop C-tag - drop frame with outer tag TPID 0x8100
Drop S-tag - drop frame with outer tag TPID 0x88A8

-32-

Drop All taggged - drop frames with outer tag TPID 0x8100 or 0x88A8

802.1Q VID Filtering

802.1Q VID Filtering function allows to admit or reject certain VID tagged packets. Up to 16 “allowed”

(positive list) or “rejected” (negative list) VIDs can be configured. This function allows limit certain frames to
pass from one link segment to another one. Disabling 802.1Q filtering function also sets VLAN to “Port-based”
mode. Enabling the function sets VLAN to “VLAN aware” mode.

[VID Table]

Disable - 802.1Q VID filtering is disabled.
Allowed VID - Only the frames with classified VIDs in VID table are admitted.
Rejected VID - The frames with classified VIDs in VID table are rejected and dropped.

Each ingress frame is classified via VLAN classification and gets one Classified Tag. The Classification Tag is
bundled to the frame in passing through VLAN operation until egress. Refer to next section for more
information.

[Tag Removal] setting

This setting is used to remove tags of the incoming frames if available. The options are:

Keep All tags - disable tag removal
Pop up 1 tag - remove up to 1 tag (outer tag if available)
Pop up 2 tag - remove up to 2 tags (outer and inner tag if available)

Egress Tagging – [Egress Tagging Rule] setting

Tag is inserted into the outgoing frame in egress operation.

Type 0 – Port Egress Tagging disabled

Type 1 – Tag all frames

Type 2 – Tag all frames, except priority-tagged frames (VID=0) and

4.4 SNMP Trap Function

SNMP trap function allows the device to send trap message to an SNMP trap host over SNMP protocol when
the associated trap event occurs.

SNMP Trap settings

The settings are used to configure a trap host who can receive the SNMP trap message issued from a media
converter device unit.

[SNNP Trap destination]

The IP address of the target SNMP trap host who is allowed to receive the traps.

[SNMP Trap community]

The community string bound in a trap message

SNMP Trap events

The following events are defined for generating a trap message when the event occurs on the unit.

 The device boot up.
 TP copper port link down
 TP copper port link up (link recovery)
 FX fiber port link down
 FX fiber port link up (link recovery)
 OPA alarm trap for FX fiber port

The following example illustrates an event of FX port link down occurs and is detected by the device. Then, it
generates a trap message to the SNMP trap host PC.

5.4.5 ALS

ALS function is provided for the SFP transceiver and used to automatically shut down the output power of the
transmitter in case of fiber break. ALS is provisioned on both ends of the fiber pair. "Auto" mode is set to turn
on transmitter automatically if the broken fiber is believed to have been repaired. The method is to turn on
transmitter at the near end for a pulse period every interval time. This pulse causes LOS (Lost of Optical Signal)
cleared at the far end if the cable has been repaired. The transmitter is turned on at the far end. At the same
time LOS cleared is also detected at the near end. Transmitters of both ends are turned on and LOS alarm is
cleared.

Manual – enable ALS and force to turn on transmitter amnaually.

Auto – enable ALS and turn on transmitter if the broken fiber is believed to have been

repaired.
Interval Transmitter is turned on for a short period as a test pulse every interval time (unit sec)

in "Auto" mode.
Width The width of the test pulse (unit sec), default 2 seconds.
Restart Check to restart transmitter for one test pulse in Manual mode

5.5.2 LLDP Statistics

Counters Description

Port The port on which LLDP frames are received or transmitted.
(Port #1: TP port, Port #2: FX port)
Tx Frames The number of LLDP frames transmitted on the port.
Rx Frames The number of LLDP frames received on the port.
Rx Error Frames The number of received LLDP frames containing error.
Discarde Frames If an LLDP frame is received on a port, and the device's internal table has run full, the

LLDP frame is counted and discarded. This situation is known as "Too Many

Neighbours" in the LLDP standard. LLDP frames require a new entry in the table

when the Chassis ID or Remote Port ID is not already contained within the table.

Entries are removed from the table when a given port's link is down, an LLDP

shutdown frame is received, or when the entry ages out.
TLVs discarded Each LLDP frame can contain multiple pieces of information, known as TLVs (TLV

is short for "Type Length Value"). If a TLV is malformed, it is counted and

discarded.
TLVs unrecognized The number of well-formed TLVs, but with an unknown type value.
Org. TLVs discarded The number of organizationally received TLVs.
Ageouts Each LLDP frame contains information about how long time the LLDP information

is valid (age-out time). If no new LLDP frame is received within the age out time, the

LLDP information is removed, and the Ageout counter is incremented.
