WDM
Opticonnects offers a range of passive WDM devices for both Dual Fiber as Single Fiber Bidirectional connections, using Wave Division Multiplexing technology. Passive WDM is a technology that enables transport of multiple network connections over optical fiber. Passive means that no power is required for the device to operate. Passive WDM devices are used in combination with WDM optics that are placed directly into the switch or server. Opticonnects passive solutions are as straightforward as possible to install and to operate and require an absolute minimum in maintenance effort.
Our passive WDM portfolio includes:
- Single Fiber Wave division Multiplexers (CWDM and DWDM),
- Coarse Wavelength Division Multiplexers (CWDM),
- Dense Wavelength Division Multiplexers (DWDM),
- Coarse Wavelength Division Multiplexing (CWDM).
Coarse Wavelength Division Multiplexing (CWDM) is the best and most cost efficient solution for operating distances of up to 80 km and a limited number of connections. For longer distances and more connections Dense Wavelength Division Multiplexing (DWDM) is the recommended technology.
CWDM
WDM or Wave Division Multiplexing knows two international standards, one of them is CWDM, Coarse Wave Division Multiplexing. Coarse indicates a larger space between the waves or, as they are commonly referred to, channels. CWDM is often used in situations where only a few channels are needed and there is no need for distances longer than 70 km. Opticonnect offers a range of Passive CWDM Multiplexers using various channels.
DWDM
WDM or Wave Division Multiplexing knows two international standards, one of them is DWDM, Dense Wave Division Multiplexing. Dense indicates few space between the waves or, as they are commonly referred to, channels. DWDM is often used in situations where more than 16 channels are required and/or distances over 80 km. Opticonnect offers a range of passive DWDM Multiplexers using the wavelengths from 1528.77 nm through 1563.86 nm with a channel spacing of 0.8 nm (100 Ghz).
Single Fiber WDM
Single Fiber or BiDirectional WDM offers a solution to scarce fibers, patch errors and fault reduction. It also saves costs where fiber has to be leased, or simply at time of installation. There is no reason not to use the technology, it is a fact that light can’t collide, even in such a narrow space of a fiber cable. Single Fiber WDM is taking advantage of the fact that the receiver in an optic has a much wider band than the transmitter, by utilizing a different wavelength transmitted from the other side the result is a perfect link.
