CWDM and DWDM equipment

CWDM and DWDM technology is well-liked by telecommunications companies simply because they provide an efficient way to share one set of fiber strands and set together various communications interfaces like: 10G, SONET OC-192, STM-64, Fiber Channel 1G/2G/4G, Gigabit Ethernet, OC3/OC12 or OC48 and E1/T1, just by using different wavelengths of light for each channel. Thus they can expand the capacity of the network without laying more fiber.

CWDM and DWDM filters are passive fiber devices that split the common fiber into different channels. They're ideal for dual fiber either or single fiber. We all do custom filters covering all 18 CWDM channels and all sorts of 60 DWDM ITU channels. We do custom Active CWDW and DWDM.

FiberStore supplies a leading CWDM and DWDM equipment. The CWDM/DWDM System products here include CWDM/DWDM Mux/Demux, CWDM/DWDM transceivers, CWDM/DWDM Add & Drop, CWDM/DWDM Transponder, Optical Amplifier, Active CWDM/DWDM and other related components.

DWDM Mux/Demux Modules are designed to multiplex DWDM channels into a couple of fibers. The common configuration is 4, 8, 16 and 32 channels. These DWDM modules passively multiplex the optical signal outputs from 4 or even more electronics utilizing a DWDM multiplexer, send on them just one optical fiber and then de-multiplex the signals into separate, and then distinct signals for input into electronics in the other end from the fiber optic link.

For example, the most popular most channel DWDM module is 32-Channel DWDM Mux/Demux. There's two kinds of this DWDM module, DWDM Mux and Demux 32 Channels by dual fiber with 1U 19 Rack Mount Box, and DWDM Mux and Demux 32 Channels by dual fiber with Plastic ABS Box. Both are well suited for increasing the fiber capacity between two sites without the need for installing or leasing additional fibers. And one is a combined passive 32 channel 100GHz DWDM multiplexer and de-multiplexer in a single 1U 19 rack mountable metal box, one is a combined passive 32 channel 100GHz DWDM multiplexer and de-multiplexer in a tiny plastic ABS box.. They both combines any 32 standard 100GHZ DWDM ITU grid channels from channels 21 to 60, and may be used in pairs or in combination with every other vendor ITU grid-compliant DWDM MUX/DeMUX. Listed here are their key features.

1.Passive DWDM System
2.Simple to install, requires no configuration, Disassembles easily for cleaning
3.The module contains 2 pieces of 32 channel DWDM multiplexers (1 mux 1 demux)
4.DWDM multiplexer to mux and demux 32 channels in C or L-band
5.Completely passive, no power required, no cooling
6.Low insertion loss - high isolation
7.Fully transparent whatsoever data rates and protocols
8.The sub-system interoperates with any router, switch, DSLAM, SFP and GBIC, which assists the DWDM ITU standard
9.The performance of Dense WDMs has been carefully designed to meet Telcordia standards GR-1209-CORE and GR-1221-CORE.
10.Accepts data rate and any protocol on any port up to 10 Gbps, also 40 Gbps (DPSK, DQPSK) and 100 Gbps (DP-QPSK)
