For wide temperature (-40 to 60º C), add a "W" to the end of the model
number. Consult factory for extended temperature (-40 to +75º C) models.
When using single-fiber (SF) media converter models, the Tx wavelength on
one end has to match the Rx wavelength on the other.

OVERVIEW:

The iConverter 100Fx/Tx converters support the IEEE

802.3 Ethernet standard and converts 100BASE-FX fiber
to 100BASE-TX unshielded twisted pair (UTP). Models
are available for multimode (MM) and single-mode (SM)
dual fiber and single-mode single-fiber.

The 100Fx/Tx supports UTP Half-Duplex and Full-Duplex
auto-negotiation with manual override and features a
crossover UTP switch for easy attachment to hubs,
switches and workstations.

The 100Fx/Tx can be used in an unmanaged or managed
fashion. When unmanaged, it can be installed in a
chassis without an
Module (NMM) or
an NMM module or 10/100M2 module must be installed in

iConverter Network Management

iConverter 10/100M2. T o be managed,

the same chassis.

LINK MODES:

In order to accommodate different user needs, the
100Fx/Tx supports three different linking modes.

The Link Segment (LS) mode transmits a link signal
independently of any received link at any port. Utilizing
this configuration, a loss of a receive link signal will only
affect the port detecting the loss of signal. All the other
ports will continue to generate a link signal. For example
a loss of link on the fiber port only affects the fiber port;
the other ports remain unaffected [Fig 1(b)].

The Link Propagate (LP) mode transmits a link signal
only when a link signal is detected. Utilizing this
configuration, a loss of a receive link signal will continue
to propagate through to the next port in the network. For

example, the fault at the fiber port is propagated forward
causing the switch port to drop its link due to the
propagated fault [Fig 1(c)].

The Remote Fault Detection (RFD) mode transmits a
link signal only when a link signal is detected. When a
loss of link is detected, this mode will perform both a
loop back and propagate forward. For example, the
fiber fault is looped back in the opposite direction causing
the port on the other media converter to lose fiber link.
It also propagates the fault forward toward the UTP port
causing the switch port to lose link [Fig 1(d)].

Note: Connecting two converters set to RFD is an
illegal setting and will cause a “deadly embrace”
lockup.

Symmetrical Fault Detection is only supported on
modules with the revision of xx/08.

In Symmetrical Fault Detection (SFD), the UTP port
transmits a Link signal only when receiving a Link at the
fiber port. The fiber port transmits a Link signal only
when receiving a Link signal at both the fiber port and
the UTP port. As a result, fiber faults (no Link received
at the fiber) are looped back and can be reported to the
network core. In addition, connecting two back-to-back
converters which are both set to SFD facilitates dual­loop-back, where fiber faults are reported to both ends
of the network link. A blinking fiber link LED on a
converter indicates a fault of the transmit fiber or UTP
cables of that converter [Fig. 1(e)].

Note: Converters in SFD mode must be deployed in
pairs.

UTP Auto/Manual Negotiate “AN/Man” DIP-Switch:

When this DIP-Switch is in the UTP Auto-Negotiate “AN”
position (factory setting), the converter auto- negotiates

(RFD+LP)

(RFD+LP)

and matches the duplex mode of a mating
auto-negotiating device connected to its UTP port.

When in the UTP Manual Negotiate “Man” position, the
converter does not auto-negotiate and operates in the
duplex mode selected by the UTP Full/Half-Duplex
“FDX/HDX” DIP-Switch.

UTP Full/Half Duplex “FDX/HDX” DIP-Switch:

When the UTP Auto/Manual Negotiate “AN/Man”
DIP-Switch is in the Manual “Man” position, the UTP
Full/Half-Duplex “FDX/HDX” DIP-Switch determines the
duplex mode for the converter.

When the UTP Full/Half-Duplex DIP-Switch is in the
UTP Full-Duplex “FDX” position (factory setting), the
converter operates in Full-Duplex mode. When in the
UTP Half-Duplex “HDX” position, it operates in
Half-Duplex mode. Set the duplex mode to match the
connecting device and check for link status.

Note: Attaching an auto-negotiating UTP port to a
non-auto-negotiating (manual / forced / hard-coded)
UTP port may result in an unpredictable port setting
with excessive collisions and poor link performance.
When operating in Manual mode both mating ports
MUST be set manually to the same speed and duplex
mode.

RJ45 Crossover “= / X” Switch (Not Shown):

When connecting the UTP to a hub or switch, set this
front-plane switch to Straight-Through “=” (factory
setting). When connecting to a workstation, set it to
Crossover “X”.

MOUNTING AND CABLE ATTACHMENT:

The iConverter modules are hot-swappable and can be
installed into any

1. Using the chassis module guides for alignment, insert
the module into the selected slot and secure using
the front panel fastener screw.

Note: Ensure that the module is firmly seated
against the backplane.

2. Using a Category 5 cable, attach the UTP port to a
100BASE-TX Ethernet device.

3. Using a multimode or single-mode dual-fiber cable as
required per the converter type, attach the fiber port
to a 100BASE-FX mating Ethernet device. The transmit
(Tx) must attach to the receive side of the mating
device and the receive (Rx) must attach to the transmit
side.

4. Single-fiber (SF) converters must be used in matched
pairs. The transmit (Tx) and receive (Rx) wavelengths
of one converter must match the receive (Rx) and
transmit (Tx) wavelengths of the mating converter.
For example, an 8370-1 must be connected to an
8371-1.
