General descripon
Funconal
The mulmode to singlemode converter 21-203, is designed to extend the maximum connecon distance between two
substaon protecon relays.
By using singlemode ber and a laser of 1300/1550nm opcal wavelength, the maximum distance can be extended up to
typically 250km, depending on the opcal budget.
For a complete link two 21-203 converters are needed.

Warning! Never look at the transming laser, at the ber Tx port or at the ber cable
ends when the transceiver is powered up!
The light is invisible, and can permanently harm your eyes!

Installaon
Serial number
The products serial number is the best way to idenfy the product. If the serial number is not noted on your delivery notes,
please add the serial number to your own product documentaon. This will be useful at future contact with Fibersystem.

Back panel
There are no connecons or indicaons on the back panel.
Fiber Opc Ports
The ber opc connectors of both mulmode port, MM, and singlemode port, SM, are of SC type.
Make sure that the right type of ber is used. Mulmode type for mulmode port (MM), and singlemode ber for singlemode
port, (SM).
Conrm that the aenuaon of the ber opc cables, including splices and patch cables, doesn’t exceed the system budget.
Don’t forget to include a safety margin. Minimum safety margin is 3dB.
At very short distances, < 1km, it might be necessary to use ber opc aenuators. An aenuaon value of 3 to 10 dB is
suitable. Two aenuators are needed.
Make sure that the local ber opc transmier, marked Tx, is connected to the remote units ber opc receiver, marked Rx. And
local Rx shall be connected to remote Tx
