1 Product overview

Figure 1 Block diagram of the WDM module operation

The Flashlink 2-Channel WDM is a wavelength division multiplexer / demultiplexer
module. The unit is passive and there is no need for power or control. The WDM is
bitrate and format transparent; meaning SDI, Ethernet and SDH/SONET is supported.
The WDM can be used for uni- directional and bi-directional application.

The optical multiplexing is made for the 2nd and 3rd optical windows (1310nm and
1550nm).

The WDM has a 1310nm, a 1550nm and a combined WDM port allowing 2 optical
signals to be multiplexed on a single fiber.

The product comes with 2 SC/UPC fiber patch cords to connect the modules together.
The product is available in the following versions:

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.

(Please note that the pictures show a not relevant product with similar mechanical
solution).

5 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 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 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.
