Modular Media Converter Installation Guide
(includes 10 Mbps Ethernet, 100 Mbps Fast Ethernet and
Protocol-Independent Fiber Mode Conversion Modules)
Modular
Media Converters
are designed to convert between 100Base-TX,
100Base-FX and 100Base-FX-SingleMode Fast Ethernet cabling, 10Base-2,
10Base-T, 10Base-FL and 10Base-FL-SingleMode Ethernet cabling or protocol-
independent single/multi-mode fiber optic cabling.
About Media Converter Chassis
Media Converter
modular chassis are user-configurable, provide power to
the media conversion module and are available with one, four, eight or 12
slots for installing any combination of interchangeable media conversion
modules that include 10 Mbps Ethernet Modules, 100 Mbps Fast Ethernet
Modules and
S2MM Module Sets
(protocol-independent single/multi-mode
fiber). For example an 8-Port
Media Converter
can be configured with one to
eight
10 Mbps Modules
and
100 Mbps Modules
or one to four
S2MM Module
Sets
in any combination.
Note: S2MM Module Sets consist of two modules and require two media conversion
module slots so they can not be used in a 1-Port chassis.
1-Port
(LE7401A and LE7401A-R2)
and
4-Port
(LE7404A)
Media Converters
are stand-alone chassis that include one or four media conversion module
slots, respectively, and a fixed 95/240 VAC power supply.
8-Port Media
Converters
(LE7408A)
are 1U high, rackmountable, include eight media
conversion module slots and a fixed 95/240 VAC power supply. There are
two
12-Port Media Converter
chassis; both are rackmountable and include
12 media conversion module slots and either a 95/240 VAC or -48 VDC
Power Supply Module with an additional slot for installing a second fault-
tolerant Power Supply Module. The basic differences between the two are
the chassis’ height and location of the Power Supply Modules. The
12-Port
Media Converter 1U (LE7412A
and
LE7412A-DC)
has the power on the rear
side of the chassis with media conversion module slots on the opposite side,
and is 1U high. The
12-Port Media Converter 2U (LE4712A-2
and
LE7412A-
2DC)
has both power and media conversion module slots on the front of the
chassis and is 2U high.

About 10 Mbps Media Conversion Modules
Media conversion modules for 10 Mbps Ethernet have two different
types of ports on them and require one slot in a
Media Converter
chassis for
a single 10 Mbps Ethernet conversion. The following versions of
10 Mbps
Modules
are available:
10BT (RJ-45) - 10BFL Module
(half- or full-duplex) — converts 10Base-T
(RJ-45) to 10Base-FL 850 multi-mode fiber; includes one pair ST
(LE740-TPSTM) connectors
10BT (RJ-45) - 10BFL SM Module
(half- or full-duplex) — converts
10Base-T (RJ-45) to single-mode fiber; includes one pair ST
(LE740-TPSTS) connectors
10BT (RJ-45) - 10BFL SM/PLUS Module
(half- or full-duplex) — same as
above only with higher power budget; includes one pair ST (LE740-
TPSTS20) connectors
10BT (RJ-45) - 10B2 (BNC) Module
— converts 10Base-T (RJ-45) to
10Base-2 (LE740-TPBNC)
10B2 (BNC) - 10BFL Module
— converts 10Base-2 to 10Base-FL multi-
mode fiber; includes one pair ST (LE740-BNSTM) connectors
About 100 Mbps Media Conversion Modules
Media conversion modules for 100 Mbps Fast Ethernet have two
different types of ports on them and require one slot for a single 100 Mbps
Fast Ethernet conversion. The following
100 Mbps Modules
are available:
100B TX - 100B FX Module
(half- or full-duplex) — converts 100Base-TX
(RJ-45) to 100Base-FX multi-mode fiber; includes one pair ST
(LH740-TPSTM) or SC (LH740-TPSCM) connectors
100B TX - 100B FX SM Module
(half- or full-duplex) — converts 100Base-
TX (RJ-45) to single-mode fiber; includes one pair ST
(LH740-TPSTS) or SC (LH740-TPSCS) connectors
100B TX - 100B FX SM/PLUS Module
(half- or full-duplex) — as above
with higher power budget; includes one pair ST (LH740-TPSTS20) or
SC (LH740-TPSCS20) connectors
About Protocol-Independent Fiber Mode Conversion Module Sets
To do a fiber mode conversion,
S2MM Module Sets
are used. Unlike
100
Mbps Modules
and
10 Mbps Modules
, each
S2MM Module Set
consists of
two modules and requires two slots in a
Media Converter
chassis to do a
single conversion. One module in the set has a single-mode receive (RCV)
port and a multi-mode transmit (XMT) port. The other module has a multi-
mode receive (RCV) port and a single-mode transmit (XMT) port. The
single-mode port is identified by a solid white bar on each of the modules.
