WARRANTY
All fiber optic transmission systems, products and accessories
manufactured by Liteway, Inc. and it’s subsidiaries are fully tested
prior to shipment and are warranted against defective materials
and workmanship for a period of five full years from the date of the
original shipment. Should a problem occur, a Return Material
Authorization Number (RMA) must be obtained from Liteway Inc.
at [phone] and the item returned to Liteway, Inc. 166
Haverford Road, Hicksville, NY 11801, USA, prepaid. Liteway Inc.
will then, at its option repair or replace the defective item.
Liteway, Inc. maximum liability under this warranty is limited to the
cost of the defective item only. No contingent liabilities of any kind
are either assumed or implied.

by unauthorized personnel will not be covered by this warranty.
Any non-warranty repairs required will be quoted at the current
rate for such services.
Important Notices
CAUTION ! AVOID DIRECT EXPOSURE TO BEAM.
All –5, -7, -8, and -9 Models use laser diodes. These solid-state
laser diodes are located in the optical ports of these units. Laser
diodes produce invisible radiation that may be harmful to human
eyes. Never look directly into the optical port of any fiber optic
unit designed to operate with single-mode optical fiber.
NOT FOR LIFE SUPPORT SYSTEMS
Liteway, Inc. does not authorize or warrant any of its products or
accessories for use in critical life support systems or applications
of any kind.

Optical Bypass Switch
Single Channel Models
OS-3141, OS-2141
Dual Channel Models
OS-3241, OS-2241
The OS-3141 and OS-2141 are four pole fiber optic switch that
can be remotely controlled. The optical path through the units
is purely optical and bi-directional, there is no optical-to-
electrical-to-optical conversion. As a result there is no electrical
loss or electrical bandwidth limit on the fiber optic path. The
optical path can be select via a front panel switch or via rear
panel contact closure or TTL level inputs. The OS-3141 and OS-
2141 are non-latching switches. The OS-2141 and OS-2241 are
latching switches.

Installation Instructions
Common applications for this device are optical routing, system
bypass, ring network restoration, and loop-back testing.
The diagram below shows the basic optical functions of the OS-3141.
Note that all optical ports are bi-directional.
OS-3141
Channel A
Channel B
Channel C
Channel D
Common
Channel
Select
The OS-3141 and OS-2141 switch will go to the D=Common state
(Optical port E) under any of the following conditions:
1) The front panel mode selector switch is set to D=Com
2) The front panel switch is set to the RMT position and the rear
panel control signals have no contact closures connected or
no TTL logic connections.
3) The OS-3141, (non-latching version), will go to the D=Com
state if or when there is a loss of electrical power. The
OS-2141,(latching version), will stay in the last know state
before the loss of electrical power.
For applications where two independent optical channels need to be
switched, the OS-3241 is two OS-3141 in parallel and in a single
enclosure.
Power Terminal Block Connections
Pin Label Function
1 No connection
2 Pwr+ +11 to +60 VDC
3 Pwr- DC return
Pin 3 of the OS-3141 and OS-2141 is connected to the housing.
Pin 3 of the OS-3141-ISO and OS-2141-ISO is floating.
Signal Terminal Block Connections
Note pin 3 is Common and/or Ground
Pin 1 = Data/Contact
Input C Pin 2 = Data/Contact Input C'
Pin 4 = Data Output C Pin 5 = Data Output C'
Pin 4 and 5 are only to be used for a master/slave system.
Power/Signal Terminal Block Remote Control Functions
When front panel switch is set to the REM position only
C C’ Optical Path
1 0 Optical Port A is routed to Common port (E)
0 1 Optical Port B is routed to Common port (E)
0 0 Optical Port C is routed to Common port (E)
1 1 Optical Port D is routed to Common port (E)
0 = contact closure from pin 1 to pin 3 or TTL logic 0 (0 to +0.8V) from
pin 1 to pin 3. 1 = no contact closure from pin 1 to 3 or TTL logic 1
(+2.7 to +5 volts) from pin 1 to pin 3. Note that pin 3 is common.

Power Proper power is present
A=Com Optical Port A is routed to Common port (E)
B=Com Optical Port B is routed to Common port (E)
C=Com Optical Port C is routed to Common port (E)
D=Com Optical Port D is routed to Common port (E)
Front Panel Mode Selector Switch
Note that the front panel selector only allows the remote control
functions to operate the switch when it is set to the REM position.
When it is set to any other position operation is as shown below.
