Figure 2: Block diagram of the WOS-2x2 and
WOS-2x2L operation. Standby position,
The flashlink ® 2 x 1 Wideband Optical Switch and 2x2 Wideband Optical Switch are fiber optical SPDT
(Single Pole Double Throw) changeover modules for use together with the WOS-C1 connector module.
Typical applications for these units are selective routing of optical signal paths without optical-to-
electrical conversion and Automatic Protection Switching (APS). The units are controlled via the
flashlink ® GYDA control system or the GPI interface.
The optical switches operate in the 2nd and 3rd optical windows (1310nm and 1550nm)
The WOS-2x1 has two input/output ports and one common port.
The WOS-2x2 has two input ports and two output ports.
The product is available in four different versions all delivered with WOS-C1 connector module:
WOS-2x1 2x1 Wideband Optical Switch, non-latching trigger type For selective routing
WOS-2x2 2x2 Wideband Optical Switch, non-latching trigger type For selective routing

3.1 Field Modification Instruction, replacement of back plane and PCB.
This Field Modification Instruction from Network Electronics ASA shows how to replace the back plane
on the flashlink frame. For questions please contact our office on tel: [phone] (0800-1600 CET),
after closing time please use our service tel: [phone]
1. If there is installed a board in the actual slot from earlier, carefully remove this board first.
2. Carefully remove all 4 screws (2 screws if a blank back plane is mounted) from the back plane to
be replaced.
3. Insert the new back plane carefully. Use your business card (or another suitable card), as shown in
figure A below, to avoid that the EMC shield is damaged when inserting the new back plane.

ure B.
4. Before tightening the screws, use one of your fingers to force the back plane to the bottom of the
frame as shown in figure B. Tighten the 2 screws at the bottom at the back plane first. This is to
avoid mismatch between the connector on the back plane and the PCB.
5. When inserting the new module for the first time, make sure that the connector on the PCB aligns
with connector on the back plane.
NOTE!
The PCB shall enter the back plane connector easily.

4. Module status
The status of the module can be monitored in four ways.
1. GPI at the rear of the sub-rack.
2. LEDs at the front of the sub-rack.
3. GYDA-SC controller.
4. Directly accessing the RS-422 bus.
Of these four, the GPI and the LEDs are mounted on the module itself, whereas the GYDA-SC controller
is a separate module giving access to remote monitoring of the status of the card through either a web
interface or SNMP. The functions of the GPI and the LEDs are described in sections 4.1 to 4.3.
The GYDA-SC controller is described in section 4.4. The commands the modules will respond to over the
RS-422 bus, can be found in section 4.5.
4.1 GPI – Module Status Outputs and switch alarm inputs, non-latching trigger type
These outputs can be used for wiring up alarms for third party control systems. The GPI output is an open
collector output, sinking to ground when an alarm is triggered. The GPI outlet is shown in figure 5. The
connector used is RJ-45.
Max output current: 100mA
Max output voltage: 30V
WOS-2x1/WOS-2x2 GPI pinning:
Signal Name Pin # Input/Output Mode
Status General error status for the module Pin 1 Output Open Collector
Standby Alarm when switch in standby mode Pin 2 Output Open Collector
Switch to standby mode Pin 5 Input
Switch to standby mode Pin 6 Input
Switch to standby mode Pin 7 Input
0V= standby
5V= main
Ground 0 volt pin Pin 8 0V
The switch is set in standby mode by sinking pin5, pin6 or pin7 to ground.
Pin6 and pin7 are hardwired as logical OR.

4.2 GPI – Module Status Outputs and switch alarm trigger inputs, latching trigger type
These outputs can be used for wiring up alarms for third party control systems. The GPI output is an open
collector output, sinking to ground when an alarm is triggered. The GPI outlet is shown in figure 6. The
connector used is RJ-45.
Max output current: 100mA
Max output voltage: 30V
WOS-2x1/WOS-2x2 GPI pinning:
Signal Name Pin # Input/Output Mode
Status General error status for the module Pin 1 Output Open Collector
Standby Alarm when switch in standby mode Pin 2 Output Open Collector
Switch to standby mode Pin 5 Input
Reset switch to main position Pin 6 Input
Reset switch to main position Pin 7 Input
0V= standby
5V= main
Ground 0 volt pin Pin 8 0V
The switch is set in standby mode by sinking pin5 to ground. Pin6 and
pin7 are hardwired as logical OR and when either is sunk to ground, they
will reset the latching switch to main position. Resetting can also be done
with GYDA system controller.

6. Laser safety precautions
Guidelines to limit hazards from laser exposure.
All the available EO units in the flashlink®range include a laser.
Therefore this note on laser safety should be read thoroughly.
The lasers emit light at wavelengths around 1310 nm or 1550 nm. This means that the human eye cannot
see the beam, and the blink reflex can not protect the eye. (The human eye can see light between 400 nm
to 700 nm).
A laser beam can be harmful to the human eye (depending on laser power and exposure time). Therefore:
!! BE CAREFUL WHEN CONNECTING / DISCONNECTING FIBER PIGTAILS (ENDS).
NEVER LOOK DIRECTLY INTO THE PIGTAIL OF THE LASER/FIBER.
NEVER USE MICROSCOPES, MAGNIFYING GLASSES OR EYE LOUPES TO LOOK INTO A
FIBER END.
USE LASER SAFETY GOGGLES BLOCKING LIGHT AT 1310 nm AND AT 1550 nm
Instruments exist to verify light output power: Power meters, IR-cards etc.
flashlink®features:
All the laser module cards in the flashlink®product range, are Class 1 laser products according to
IEC 825-1 1993, and class I according to 21 CFR 1040.10 when used in normal operation.
More details can be found in the user manual for the FR-2RU-10-2 frame.
Maximum output power*: 5 mW.
Operating wavelengths: > 1270 nm.
*Max power is for safety analysis only and does not represent device performance.

this part is below the limit requirement in SJ/T11363-2006.
X: Indicates that this toxic or hazardous substance contained in at least one of the homogeneous
materials used for this part is above the limit requirement in SJ/T11363-2006.
Environmentally-friendly use period
The manual must include a statement of the “environmentally friendly use period”. This is defined as the
period of normal use before any hazardous material is released to the environment. The guidance on how
the EFUP is to be calculated is not finalised at the time of writing. See
http://www.aeanet.org/GovernmentAffairs/qfLeOpAaZXaMxqGjSFbEidSdPNtpT.pdf for an unofficial
translation of the draft guidance. For our own products, Network Electronics has chosen to use the 50
year figure recommended in this draft regulation.
Network Electronics suggests the following statement on An “Environmentally Friendly Use Period”
(EFUP) setting out normal use:
EFUP is the time the product can be used in normal service life without leaking the hazardous materials. We expect the normal
use environment to be in an equipment room at controlled temperature range (0ºC - 40ºC) with moderate humidity (< 90%, non-
condensing) and clean air, not subject to vibration or shock.
Further, a statement on any hazardous material content, for instance, for a product that uses some tin/lead
solders:
Where a product contains potentially hazardous materials, this is indicated on the product by the appropriate symbol containing
the EFUP. The hazardous material content is limited to lead (Pb) in some solders. This is extremely stable in normal use and the
EFUP is taken as 50 years, by comparison with the EFUP given for Digital Exchange/Switching Platform in equipment in
Appendix A of “General Rule of Environment-Friendly Use Period of Electronic Information Products”. This is indicated by the
product marking:
