Q:

Can you tell me the difference between DWDM tunable optical module and standard DWDM optical module?

Por S***s en 09 de nov. de 2021

A:

The biggest difference between them is that DWDM tunable optical module can adjust the wavelength, and usually worked as a spare optics, while the standard DWDM optical module is fixed and specific wavelength.

Q:

I want to konw that Is there any difference between CWDM industrial-grade modules and DWDM industrial-grade modules with the same transmission distance.

Por M***b en 01 de oct. de 2021

A:

First, CWDM and DWDM have different wavebands, and the corresponding optical transmission schemes are different. Second, DWDM can be used with amplifiers, but CWDM modules cannot.

Q:

I'm wondering what the difference is between DWDM and CWCM in terms of connection scheme.

Por R***o en 31 de agto. de 2021

A:

DWDM is generally connected to EDFA, DCM and Transponder, CWDM is primarily a direct connection, or a connection to an OEO (Transponder).

Q:

Is it possible to deploy a hybrid CWDM/DWDM network on a pair of fibres? How can it be deployed?

Por D***r en 09 de agto. de 2021

A:

Yes, you can connect 1530nm or 1550nm CWDM channels to the line ports of DWDM Mux Demux. CWDM 1530nm matches DWDM's narrow band C53-C60 and CWDM 1550nm matches DWDM's narrow band C27-C42.

Q:

Is there anything I need to pay attention to when I choose the wavelength of this transceiver?

Por M***o en 15 de jul. de 2021

A:

Yes, it depends on whether you have MUX or not. if you have MUX, you can choose channels to match with the available channels of your DWDM Mux Demux, if you just plan a direct connection of 2 modules, any channels is ok for you.

Q:

Hello, there is a problem that my switch does not support DWDM modules, is there any solution?

Por R***e en 06 de jun. de 2021

A:

Don't worry, i was told by my AM that OEO can be used to convert non-WDM signals to WDM signals , and that you can use DWDM on your switch well.

Q:

What wavelength range and channels are supported by 10G DWDM SFP+?

Por C***r en 25 de my. de 2021

A:

DWDM transceivers support 45 channels (C17~C61), from 1563.86 nm to 1528.77 nm in 100Ghz grid.

Q:

How to clean the 10G DWDM SFP+ transceivers?

Por W***n en 27 de abr. de 2021

A:

FS NEOCLEAN-EZ LC/MU 1.25mm Pen One-Push Cleaner (750 cleans) is recommend, it works so well that I still use it.

Q:

Is the wavelength of the standard DWDM optical module the same as the DWDM tunable optical module?

Por O***l en 13 de abr. de 2021

A:

I was told by FS that there is not much difference in wavelength between them, but the tunable optics can be configured to a fixed channel.
