4 Channels CWDM MUX/DEMUX, 1270nm to 1330nm, IL=1.5dB, LC

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

FiberOnSale 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.
FiberOnSale 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.

Front Panel Details

Wavegate front panel detaild example

A. Common port:
● LC, SC, ST and FC connectors available.

B. Standard port 1310nm:
● Allows a legacy 1310nm signal to pass. That is to say, it can carry LR optics, LX optics etc.
● LC, SC, ST and FC connectors available.

C. Standard port 1550nm:
● Allows a legacy 1550nm signal to pass. That is to say, it can carry ER optics, ZR optics, LX optics, ZX optics etc.
● LC, SC, ST and FC connectors available.

D. 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, need more details, please contact at info@FiberOnSale.com
● 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.
