1 - OVERVIEW
A media-converter may be defined as a device connecting two active network
components point-to-point over a media that is different from the ports of at least one of
these devices.
An ideal media-converter should be a transparent element in the network, and its ports
may be considered as integral parts of the devices interconnected by it.The IEE802.3u
standard defines network span in terms of distances and bit times.
Conventional 100Base-TX/100Base-FX media-converters are based on repeater
technology, and they form a part of the collision domain created by the interconnected
devices. Therefore, the delay they introduce in the network severely affects the allowed
distances. Furthermore, if two class II repeaters (i.e., 2 hubs) are already present in the
same collision domain, then the use of a conventional converter is not allowed as the
repeater count may - in such case - exceed the limits. In all other cases, meticulous
PDV (Path Delay Value) must be performed prior to establishing the possible distances
for both the fiber optic (F/O) and copper segments.
The Black Box®LB1350A/LB1351A family implements a non-repeater, full re-timing
approach. It creates a Buffered Media Domain (BMD) over the F/O link, thereby
eliminating all the above mentioned limitations.
The BMD created by two Black Box®LB1350A/LB1351A devices always operates at
maximum performance - 100Mbps/Full Duplex - while interconnected devices may
operate at different rates and modes. This provides full flexibility when planning a
network.
The Black Box®LB1350A/LB1351A provides 4 (3) TP ports sharing conversion to one
FO port, with the TP ports buffered and VLAN protected between themselves, making
the device an ideal and most economical solution for both FTTH (Fiber-To-The-Home)
and FTTD (Fiber-To-The-Desk) applications.
2- Planning your Network with Black Box®LB1350A/LB1351A
Below you will find a FTTD co nfiguration. The drawing demo nstrates the versatility of
the device in terms of interconnecting – trouble-free – other devices.

A Black Box®LB1350A/LB1351A will be deployed in a home or building and connected
by fiber to axxess switch.
It may be deployed on a floor of an apartment (office) building and 4(3) apartments
(offices) may be connected to it’s copper ports without the need to verify the type of the
network (device) within the apartment (office).Also a HUB or Switch can be connected

Note: RJ-45 port No. 4 is a preferred port with enhanced functionality – see section 5.
As each of the Black Box®LB1350A/LB1351A RJ-45 port 4(3) supports: full autonegotiation, auto-polarity and auto-cross, you can simply connect any device to any port
by using a standard straight or crossed cable. In particular, you can connect 10Mbps or
100Mbps devices as well as HDX/FDX devices.

Black Box®LB1350A/LB1351A
The Black Box®LB1350A/LB1351A will not only convert signals from copper to fiber
but also from 10 to 100Mbs and HDX to FDX, thus ensuring maximal distance over the
optical link.
All you need to take care of is the Speed and Duplex mode balance across the network:
if one of the local devices is HDX only capable you should force the corresponding
remote device to HDX as well to avoid buffer overflow. Same applies to devices with
10Mbps capability only.
Disregarding the interconnected device F/O link will always operate at 100Mpbs and
FDX (you may force it to HDX as well, if needed )
3 - CONTENTS OF THE SHIPPING CONTAINER

Black Box®LB1350A/LB1351A
General Description
The Black Box®LB1350A/LB1351A is a shared and buffered media converter. It
converts 100Base-FX signals received on its F/O interface in 10/100Base-TX signals
and distributes them to 4(3) copper (shielded RJ-45) ports. Each of these ports is
buffered; furthermore, factory set VLAN forms groups each including one copper port
and the common F/O port, providing the users with basic security (no connection
between the users). This architecture allows 4(3) users to share one F/O link with
dramatic (up to 75%) savings.
The copper ports are auto-negotiating and will automatically adapt themselves to the
capacity of the users for highest performance (will negotiate 10/100 and FDX/HDX).
Nevertheless, in some cases it may be necessary to force certain operating modes.
For this purpose, all copper ports may be (individually) forced to 10Mbps/FDX
operation and port #4(3) (the preferred port) may be forced to any desired combination
(altogether 4 combinations) of HDX/FDX and 10/100.
Full front panel diagnostics provide information on the operation mode of every port.
The F/O port is configured by default to FDX but if desired may be set to HDX as well.
However it is essential to remember that when in HDX, the F/O link maximal distance
drops to 412m or less.
The Black Box®LB1350A/LB1351A is available with a variety of multi-mode and singlemode interfaces with distance ranging from 2km to 40km.
The Black Box®LB1350A/LB1351A is packaged in a rugged “half rack” enclosure
allowing elegant and safe deployment in a variety of environments: desktop, 2 units on
a 19” rack-shelf or within a standard “half 19” rack (optional brackets required).
Its internal, high-power auto- range switching power supply ensures easy, safe and
error-free deployment and enhanced MTBF.
The managed version – Black Box® LB1351A – provides full in-band SNMP
manageability (both monitoring and control) - see Appendix A ( pages 19-37 )
Port priority schemes are also a part of the management.
5. PREFERRED PORT
TP port #4 of the Black Box®LB1350A (or #3 of the Black Box® LB1351A) provides
additional functionalities comparing to the other copper ports.
Full operation mode selection
While all the T P ports provide auto-negotiation and forced 10Mbps/FDX operation, this
preferred port may be set via the front panel DIP switches to force all possible operation
mode options: 10/HDX, 10/FDX, 100HDX and 100FDX. See section 12 for detailed
Dip switches setting ( page 14 ).
Recommendation: use the preferred port for connection of the most critical or
heavy traffic user of the four, even if you do not implement the special features
described above
6. Far End Fault Signaling ( FEF ) feature
When the device detects F/O Link Loss (receive side) it automatically sends a Far End
Fault signal to the remote device. If such device is another Black
Box®LB1350A/LB1351A or any device which supports such feature – then it will
indicate F/O Link Loss as well. By activating TEST mode (by TEST switch - #8 MODE
SETUP Dip switches on the front panel ) this function may be disabled .The picture
below depicts this functionality.
9
Black Box®LB1350A/LB1351A
If there is a fault in the outgoing path and the remote device is FEF compliant (see
below) then the F/O LINK LED will go OFF on both the local and remote devices. In this
way we avoid the possibility of having a FX Link ON indication at one end while, in
reality one of the data path is disrupted.

For Desktop use:
protecting sheet) to the bottom of the devices, with each “foot” approximately 1 cm from
each edge.
Place the device horizontally on a hard, clean surface (desk, shelf, etc.), leaving free
space around it for natural ventilation. Avoid putting the device on other active, heat
generating equipment and avoid putting such devices on the Black
Box®LB1350A/LB1351A
Affix the supplied plastic “feet” (after peeling off the adhesive
19” Rack installation
Use a standard flat shelf, install it in the rack and place one or two Black

2-3cm above the unit.
9 - POWER CONNECTION
CAUTION: When connecting a device to an AC) power outlet,
always first connect the cord to the device, and ensure that it
is securely fastened. Only afterward connect the cord to the
wall outlet .Make sure to use grounded ( 3 way ) outlets.
For each country Black Box provides with the product an appropriate power
supply cord which is safety approved in accordance with such country’s
National Electric Code
Black Box®LB1350A/LB1351A
Connect AC line voltage at the rear of the converter, using the included power cord. The
Black Box®LB1350A/LB1351A will accept any line voltage from 100 to 240 VAC, 50-60
Hz.
There is no ON/OFF switch on the device. When the power is connected to the device,
the device is ON. This will be indicated by the POWER LED ON.
Important: following any connection or setup change (sections10,11,12
below) you must reset the device by either using S9 or by disconnecting
power and reconnecting it after few seconds
