CWDM/DWDM Video Tutorials

CWDM / DWDM Tutorial 01 - Optical-Power-Meter

This is a short introduction to the Solid Optics Optical Power Meter. We explain in this video the use of the device and how you can use the Optical Power meter in your setup.

CWDM / DWDM Tutorial 02 - Portable Optical CWDM Meter

This is a short introduction to the Portable Optical CWDM Meter. We explain in this video the use of the device and how you can use the Portable Optical CWDM Meter in your setup.

CWDM / DWDM Tutorial 03 - Portable Optical DWDM Meter

This is a short introduction to the Portable Optical DWDM Meter. We explain in this video the use of the device and how you can use the Portable Optical DWDM Meter in your setup.

CWDM / DWDM Tutorial 04 - Optical-Power-Meter Lambda settings

This Movie will expain how to use the Lambda button on the Solid Optics Optical Power meter. The Powermeter uses a InGaAs detector which has different sensitivity for different wavelengths. To get the correct dBm you would need to set it a wavelenght which is close to the wavelenght you are measuring.

CWDM / DWDM Tutorial 05 - CWDM or DWDM

In this movie, Solid Optics will explain the advantages and disadvantages of using CWDM or DWDM.

Solid Optics Tutorial 05 - CWDM BiDi setup 04

This video will explain how you can make your own CWDM BiDi setup and how it works.

Solid Optics Tutorial 06 - Basic CWDM DWDM setup

This video gives you a brief explaination of how to setup a network with cwdm/dwdm muxes.

Solid Optics Tutorial 07 - 10 must knows about CWDM

The CWDM technique combines different light sources (colors) using a passive mux over dark fiber to another location (data center). This allows you to increase bandwidth over by sending multiple data streams over your dark fiber lines.

General information about CWDM/DWDM

Wavelength division multiplexing is a technique used to transmit multiple signals through one fiber using different wavelengths. The technique has become very popular because of the high costs for renting or buying extra dark fiber. This technique is very cost-effective to increase bandwidth.

CWDM

Coarse Wave Division Multiplexing uses steps of twenty nanometer per optic. Starting at 1270nm and ending at 1610nm it consists out of eighteen different ‘colors.’ CWDM is very beneficial at 1G as the optics are extremely cheap and can reach distances up to 180 kilometers. 10G CWDM is less popular because the lower wavelengths cause a lot of attenuation, only wavelengths 1470 - 1610 are used for distances up to eighty kilometers.

DWDM

Dense Wave Division Multiplexings uses steps of 0,8nm per optic. The wavelength are centered around 1550nm (C-Band, 1530 – 1565nm) and are available in 64 different channels. The most commonly used are channels 18 – 61.  DWDM is popular for long distances because the signal can be amplified using an Eribium Doped Fiber Amplifier, Raman amplification or Semiconduction Optical Amplification.

Solid Optics provides CWDM and DWDM multiplexers in various forms. Small trays for outdoor usage and 19’’ rack units for indoor applications. By testing every port for attenuation we can give you a life-time warranty on our MUXes. Every MUX comes with a test report to show every attenuation of every port. Most CWDM and DWDM optics are not available in the portfolio of the bigger router and switch manufacturers. Solid Optics is able to deliver nearly every optic for nearly every switch.
