1.0 Product Description
The SX-4FX, 4 channel fiber switch is part of Meridian’s continuing expansion of fiber
transport products to provide improved fiber network security and reliability. This card is
designed to provide the ability to selectively switch the single-mode fiber optical input to
any one or all of the switched outputs. As an all-optical switch, this device is data type and
rate agnostic and can switch video, audio or data signals via input single-mode optical
fiber. Each port of the switch can be controlled either locally, using the front-panel
mounted DIP switch, or remotely, using the USB interface or Meridian’s SpectraSmart
network management system. Front panel mounted indicator lights show the status of each
output port (on or off) as well indicating the mode of operation (local/remote).The switch
is not latching so it will not retain its state during a loss of electrical power.
This card can also be used with bi-directional information such as camera PTZ control and
video conferencing systems, but only one output port can be selected.
The functionality of this card is enhanced by its compatibility with Meridian’s PC based
SpectraSmart network Management and remote diagnostic software system. SpectraSmart
monitors the operating parameters of the card and allows the user to remotely select the
optical transmission path. See SpectraSmart brochure for additional details.
Optional GPI control port is available, by adding “J” on the end of part number.
And optional conformal coating provides an additional level of protection from
environments with high humidity and condensation.
2.0 Installation
The SX-4FX series products are Meridian’s standard one-slot wide, 3RU cards and
occupy one slot in Meridian’s standard chassis (SR-500/S, SR-1002/S, SR-1600/R and
SR2001 & SR-2000 series 19” equipment chassis). To install in the chassis, orient the card
with the Meridian logo at the top of the module and slide onto the top and bottom card
guides in the chassis. Press securely on the top and bottom of the module to ensure that it is
fully seated in the chassis so that the electrical connector mates with the chassis-mounted
motherboard. Once installed, manually tighten the two thumbscrews located at the top and
bottom of the card. Do not use tools to secure these and do not over tighten.
Note: A fully populated subrack should have forced-air cooling to avoid excessive heat
buildup inside the chassis. A fan assembly tray (P/N FA-2000/1) with there (3) fans is
available from Meridian and should be installed under the 19” SR-2000/1 whenever
possible.

2.1 Fiber connections
These cards are designed for singlemode fiber and are available with either FC or ST
optical connectors. See part # selection guide in appendix for ordering details.
3.0 Local/Remote Control
The card has one optical input port and four optical output ports with green-color LED
associated with each output port. The green LED, associated with each output port, shows
which port is currently active.
There is the “Port Control”, five position DIP switch located directly below the front panel
mounted optical output connector 4. The four top switches select the input ports activites
and , the bottom switch select the “Local or Remote”. In the Local position port activity
can be controled by switches position 1 to 4. In the Remote position port activity can be
control by USB interface connection to PC or SpectraSmart network management system
(SSPC). Input optic signal can be bidirectional when only one output port selected.
Optional GPI control port is available via RJ-11 connector. Five Contact Closure GPI
inputs can be used to control switch by closing inputs to ground. The table below illustrates
how they are configured.

4.0 USB Interface Control
USB interface is USB2.0 & USB1.1 compatible and has mini connector. The Remote
mode / by USB or SSPC/ will be controlled, when position 5 of the DIP switch on the
front panel in ON. In the remote mode USB interface connection has a priotity over SSPC.
SSPC will control when USB is disconnected from PC. Each optical switch of the output
ports 1,2,3,4 can be turned on or off, independently of the other switches. Any one,
combination of switches or all switches can be turned on or off independently. Adjacent
to each optical output connector there is an indicator light to indicate the switch’s status /
ON = GREEN /.

Page 5
If the switches are set by the software / DIP switch in REMOTE setting / , when the USB
is disconnected, the switch will stay in that position set by the software prior to being
disconnected from the PC. When the DIP switch put back into LOCAL mode , each of the
optical switches be configured as defined by the front panel DIP switches.
Software have a feature to lock/unlock the switch setting to avoid inadvertent switch
changes someone from the PC.
Static mode:
Run progam by clicking START, then “ALL PROGRAMS” and choose menu “Optical
Fifer Switch 1x4”. The program find virtual Comm port # and open windows ”1x4 Optical
Fiber Switch Card Interface” and “Switch Status and Time Table”.
If there is no connection, check or connect the PC to card via USB cable and click on
“Connection” button in window . Than click menu “Settings” and then “Switch Status
and Time Table” -window”Optical Fiber Switch 1x4 Card Interface” is appeared.

5.0 SpectraSmart Software Control
SpectraSmart PC is a Windows 2000/XP/Vista/7 based Link Status Monitoring and
Diagnostic System. The SpectraSmart scans card parameters in sequential order,
checking for levels against factory/user set threshold values. If an error or out of range
condition is detected, the PC will continue to scan through system components until the
error condition has been detected 3 times before showing an Alarm message. This helps
ensure that the detected condition is an actual occurance and not simply an anomaly.
The screen shots below illustrate what the computer displays when the SpectraSmart
software is operated. This first screen shows a display of the card’s front panel layout
and identifies the various indicators and associated input/output interfaces. When an
valid alarm is generated and identified the 2nd alarm display will be shown on the screen
indicating what card generated the alarm as well as the cause of the alarm. When
triggered, the “Suggestion” button will suggest appropriate corrective action to be taken
to correct the alarm.
