WDM Multiplexer is a device that uses Wavelength Division Multiplexing (WDM) technology to combine different optical wavelengths from two or more optical fibers into just one optical fiber. This combining or coupling of the wavelengths can be very useful in increasing the bandwidth of a fiber optic system. WDM multiplexers are used in pairs: one […]

Current Situation of the Development of CWDM
In order to research the present situation and the existing problems about CEDM technology, Fiberstore invited some equipment manufacturers include Huawei, Shanghai bell alcatel(asb), CIENA, light bridge, Fire network to test CWDM equipments. Main test content includes: Main optical channel MPI interface, OTU testing, business interface testing (including SDH, Ethernet, transparent rate channel interface, ESCON, […]
The Future Trends of CWDM Transceivers
There are several trends for transceiver development with the majority of activities occuring at 10 Gbps, where DWDM XFPs are increasingly being deployed. Additionally, there is another new MSA standard called Quad Small Form Pluggable (QSFP), that is pushing the bit-rate to a 16-Gbps limit, thus promising a 3-times density improvement over current solutions. Jobs […]
A Comparison between CWDM and DWDM
Transporting a single data stream through an optical fiber can be costly and inefficient. Wavelength Division Multiplexing (WDM) technology can transmit multiple, independent data streams through a single optical fiber to better utilize the bandwidth of the given optical fiber. Each data stream adopts a different wavelength of light (also know as lambda λ) and […]
Using CWDM Technology To Construct Cost-Effective Fiber Networks
The utilization of fiber optic cables for communication has opened up gates for communication multiplexing technologies that increase the capabilities at minimum costs. Coarse wavelength division multiplexing (CWDM) modulates different wavelength laser beams with multiple signals. Essentially, what this means is maximized utilization of a single fiber optic to deliver and get a large number […]
Multiplex Your Fiber by Using CWDM or DWDM
Using a WDM(Wavelength Division Multiplexing) for expanding the capacity of the fiber to carry multiple client interfaces is a highly advisable way as the physical fiber optic cabling is not cheap. As WDM widely used you must not unfamiliar with it, it is a technology that combines several streams of data/storage/video or voice protocols on the […]
