1 Product overview
The Flashlink CWDM (Coarse Wavelength Division Multiplexing) system is based on an alloptical module for multiplexing and demultiplexing 18 CWDM wavelengths according to ITUT G.694.2. The unit works similarly in both directions and can be used as mux as well as
demux.

3 Mounting the CWDM module into frame
The CWDM filter must be mounted in a Flashlink sub rack. This is done from the rear. Do not
use force when inserting the CWDM filter. The module’s main board has a special design to
utilize both card rails in the FL sub rack. In order to enter the lower rail before sliding the unit
into its final position, please follow the method shown in the pictures below.

4 Laser safety precautions
These are 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 even though there is no laser
onboard this product.
The lasers emit light at wave lengths between 1271 nm and 1611 nm. This means that the
human eye cannot see the beam, and the blink reflex cannot 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 fibre pigtails (ends).
Never look directly into the pigtail of the laser/fibre.
Never use microscopes, magnifying glasses or eye loupes to look into a fibre
end.
Use laser safety goggles blocking light between 1271 nm and at 1611 nm
Instruments exist to verify light output power: Power meters, IR-cards etc.
Flashlink features:
The FR-2RU-10-2 is classified as Class 1 laser product according to EN 60 825-1:94/A11:96,
and CFR Ch1 (1997) Part 1040.10.
If the front panel is removed, the FR-2RU-10-2 is classified as Class 1 laser product
according to EN 60 825-1:94/A11:96, and class IIIb according to CFR Ch1 (1997) Part
1040.10.
Maximum output power1: 17 mW
Operating wavelengths: > 1260 nm
Max power is for safety analysis only and does not represent device performance.
