1Product overview
The Flashlink CWDM (Coarse Wavelength Division Multiplexing) system is based on all-
optical modules for multiplexing and demultiplexing 8 CWDM wavelengths according to
ITU-T G.694.2. Two sets of wavelengths, one from 1470 to 1610nm (1-8) and one from
1270 to 1410nm with an upgrade port. By use of the upgrade port, up to 16 optical signals
can be run over a single fibre. The units are passive and all-optical devices, requiring no
power supply or control. Any number of channels can be used to transport signals in one
direction with the rest of the channels transporting signals in the other direction. The units
can be cascaded through the upgrade ports in the 9-16 module.

3.1 Mounting the CWDM filter
The CWDM filter must be mounted in a Flashlink subrack. This is done from the rear of the
subrack. Do not use force when inserting the CWDM filter, once the module’s upper rail
aligns with the card rail in the subrack, it should slide easily into place. Lock it with 4
M2.5x8mm screws.
Figure 2: CWDM-1-8 mounted in a Flashlink subrack.
3.2 1-8 channel system
Connect each of the optical ports to the corresponding optical port on the receiver or
transmitter that matches the signal type and wavelength.

3.3 9-16 channel system
Using the upgrade port of the CWDM-9-16 enables to have up to 16 wavelengths on a
single fibre.
Each set of 8 channels must first be connected like described in chapter 3.2, figure 3.

4Laser 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 1310 nm or 1550 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 at 1310 nm and at 1550 nm
Instruments exist to verify light output power: Power meters, IR-cards etc.
