WDM Optical Network
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. Powerlink, backed by China factories, supplies a complete series of WDM Optical Network Solutions, such as multiplexers, splitters, amplifiers, attenuators, transceivers and other active or passive optical components. We provide the best products to help build and expand fiber optic networks. Customers can buy these products directly from categories below or Make Customized Orders.
WDM optical networks need multiplexer (MUX) and demultiplexer (DEMUX) to combine and split the multi-wavelength optical signals. The MUX is used to join signals together at the transmitter, while the DEMUX) is used to split signals apart at the receiver. CWDM networks use CWDM modules such as CWDM MUX/DEMUX and CWDM OADM. DWDM networks use DWDM modules such as DWDM MUX/DEMUX and DWDM OADM. Powerlink provides a series of WDM modules which enable the expansion of existing fiber capacity. Our CWDM DWDM OADM modules are available with three packagings: ABS Pigtail Module, Rack Chassis and LGX Cassette.

CWDM MUX DEMUX
Coarse Wavelength Division Multiplexing (CWDM) networks need multiplexer/demultiplexer (MUX/DEMUX) modules to combine and split the multi-wavelength optical signals. These modules are generally called CWDM MUX/DEMUX. Coupled with highly reliable passive optics (e.g., CWDM SFP/SFP+), CWDM MUX/DEMUX modlues let operators make full use of available fiber bandwidth in local loop and enterprise architectures. Powerlink provides a series of CWDM MUX/DEMUX modules with as more as 18 channels (20nm spaced) in simplex or duplex configurations. All the CWDM modules are available with three types of packaging: ABS Pigtailed Box, Rack Chassis and LGX Cassette.

Duplex CWDM MUX & DEMUX
Multiplexer (MUX) and demultiplexer (DEMUX) are combined together into a single piece of equipment for bi-directional data transmission over two fibers.

Powerlink CWDM Mux/Demux is a passive technology, it allows for any protocol to be transported over the link, as long as it is at a specific wavelength (i.e. T1 over fiber at 1570nm transported alongside 10Gbps Ethernet at 1590nm). This allows for long-term future proofing of the networking infrastructure because the multiplexers simply refract light at any network speed, regardless of the protocol being deployed.

Powerlink provides a complete portfolio of CWDM Mux Demux and Optical Add Drop Multiplexer (OADM) units to suit all applications such as: Gigabit & 10G Ethernet, SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV. And we provide optional port configurations such as: Express Port, Monitor Port, 1310nm passband port and 1550nm port for these multiplexers according to customer choice.

Mux/Demux port for specific wavelengths:
LC, SC, ST and FC connectors available.
Compliant with the ITU G.657A1 standard as default.
E
Express port:
Enables the cascading of two CWDM mux/demux modules, doubling the channel capacity on the common fiber link.
Channel Isolation is 15dB as default, 16dB ~40dB available on request.
LC, SC, ST and FC connectors available.
F
Monitor port:
Connects measurement/monitoring equipment, such as power meters or network analyzers, to the module outputs.
When finished monitoring, disconnect the instruments and the network is left undisturbed.
LC, SC, ST and FC connectors available.
Tap percentage is 5% as default, 1%, 2%, 3%, or 10% available on request.

NOTE:
Actual layout depends on the chosen connector type as well as other factors. However, the principal scheme stays the same
We provide optional port configurations such as: Express Port, Monitor Port, 1310nm passband port and 1550nm port for these multiplexers according to customer choice. When using with 1310nm legacy SDH/SONET, CWDM wavelengths 1270, 1290, 1310, 1330 and 1350nm should not be used.
When using with 1550nm legacy SDN/SONET, CWDM wavelengths 1510, 1530, 1550, 1570 and 1590nm should not be used.
