It helps customers improve the yield, quickly enhance transmission network bandwidth, improve the efficiency of network operations, reduce operation costs, realize the network security and achieve the cooperation pattern. After years of development, it all have good performance , in optical fiber access network, optical transmission network and other aspects and has become an optical communication innovative high-tech enterprises.
The CWDM mux /demux (or CWDM multiplexer /demultiplexer) is often a plug- and-play flexible network solution that helps insurers and business companies to implement affordable point or base ring denote WDM optical networks. CWDM Mux/demux is perfectly created to transport PDH, SDH / SONET, Ethernet services over WDM, CWDM and DWDM optical front line metro and access networks.
CWDM multiplexer modules can be found in configurations 4, 8 and 16 channels. These modules passively multiplexing the optical signals output from 4 too many electronic products , sends them over one optical fiber and then de- multiplexing the signal into separate and distinct for gadgets input signals across the opposite end of the connection optical fiber.
CWDM solutions typically provide 8 wavelengths enable the transport capacity of eight customer interfaces through the same fiber. However, the relatively large spacing between the CWDM wavelengths allows expansion of the CWDM network with an additional of 44 wavelengths with a spacing of 100GHz using DWDM technology, thus increasing the capacity of existing infrastructure and using the same equipment as part of the integrated solution.
DWDM is a technology which allows high capacity throughput over longer distances typically ranging between 44-88 channels / wavelengths and transferring data rates from 100Mbps up to 100Gbps per wavelength. Packet multiplexer 16 channels or more channels in the spectrum of a narrow window near the 1550nm local attenuation minimum. Decreasing channel separation requires the use of precise and expensive optical, but allows for significantly more scalability. DWDM systems typically provide 1-44 channel capacity with some new systems, offering up to 80-160 channels. DWDM is typically used where high capacity over one fiber limited or where it is cost prohibitive to deploy more fiber resource is needed.
DWDM multiplexer/demultiplexer modules are made to multiplex multiple DWDM channels in one or two fibers. Based on CWDM unit Mux/Demux type, with optional expansion, can transmit and receive as much as 4, 8, 16 or 32 connections of different standards, rates or data protocols over a single link optical fiber without disturbing each other. Ultimately, the choice of using CWDM or DWDM is a difficult decision; we should first understand the difference between them clearly.
