Just as we FiberStore.com is a worldwide leading manufacturer & supplier of fiber optic products, and our goal is to be “Source of Optic Communication”, we are specialized in fiber optic communication products. For example, we can provide various of the CWDM Muxand Demux at good price and guaranteed quality, and they are really popular among our customers.
Now talking about the CWDM Mux/Demux (we can also provide the DWDM Mux/Demux), we should know that in the fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e. colors) of laser light. This technique enables bidirectional communications over one strand of fiber, as well as multiplication of capacity. And usually, a WDM system may uses a multiplexer at the transmitter to join the signals together, and a demultiplexer at the receiver to split them apart, that is exactly the working principle of our CWDM multiplexer and demultiplexer. Generally speaking, the CWDM Mux and Demux products can be applied in the following fields: All Enterprises and Carrier with Fiber Optic Infrastructure, Transmit additional applications via existing lines, Connect buildings to CWDM campus ring, Connect Field offices to central office, Ideal solution for metro-core, metro-access and enterprises. And the key features for our CWDM Mux/Demux with 1U 19 Rack Mount Box are: a. The Mux and Demux are combined in one 1U box. b. It compliant to ITU-T G.694.2 CWDM standard. c. It is completely passive, no power supply needed. d. All the date rates are fully transparent and protocols from T1 to 40 Gbps. e. It is of low-cost transceivers applicable, existing equipment can still be used. f. It accepts any data rate and any protocol on any port up to 10 Gbps, also 40 Gbps (DPSK, DQPSK) and 100 Gbps (DPQPSK). g. It meets the ISO 9001 stand. h. They are really simple to install, requires no configuration or maintenance. i. We provide lifetime warranty for it.
PS: Of the relationship of WDM, DWDM and CWDM, these three are based on the same concept of using multiple wavelengths of light on a single fiber, but differ in the spacing of the wavelengths, number of channels, and the ability to amplify the multiplexed signals in the optical space.
