CWDM BiDi technique is becoming more interesting as a fiber-to-the-home solution. GPON is still the most commonly used application for fiber-to-the-home, but some Internet Service Providers are encountering issues with this technology - This is where CWDM BiDi comes in as a welcome alternative to minimize the changes needed on your current Ftth infrastructure.
The prices of 10G multimode and single mode modules are very stable and it is becoming more economically feasible to upgrade to 10G modules. The most commonly used form factors are XFP and SFP+. Solid Optics can supply all form factors coded for all brands in all quantities.
CWDM and DWDM are the most popular techniques to maximize bandwidth over dark fiber. Coarse Wavelength Division Multiplexing (CWDM) is chosen over Dense (DWDM) for 1G speeds and for short distances at 10G. CWDM is also beneficial for outdoor applications because DWDM is more sensitive to shifts in temperature.
Dense Wavelength Division Multiplexing is used to take your dark fiber to the extreme. Especially for long distances on 10G, DWDM has many benefits over CWDM. The small spacing makes it possible to carry up to 80 times 10G over a single dark fiber, and the signal can be amplified to achieve extreme long distances without having to be repeated.
