Dual Fiber CWDM Mux Demux

Dual Fiber CWDM Mux Demux is a device used in fiber optic communications that employs Coarse Wavelength Division Multiplexing (CWDM) technology to multiplex and demultiplex multiple signals over two optical fibers. It enhances transmission stability and performance by using two fibers for separate sending and receiving. CWDM Mux Demux combines multiple signals with different wavelengths onto a single fiber for transmission and then demultiplexes them back into individual signals at the receiving end, significantly increasing the transmission capacity of a single fiber. With its larger wavelength spacing (typically 20nm), CWDM allows the transmission of multiple wavelengths on one fiber. This device is widely used in metropolitan area networks, access networks, and data centers to boost network bandwidth and efficiency, offering low insertion loss and high isolation for high-quality signal transmission.

Specifications

Example: LGX Module, Duplex, CWDM Mux & Demux

Front Panel Details：

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.These are available in ITU G.652, ITU G.652C and ITU G.652D on request. The 1390 and 1410 wavelengths are not recommend at ITU G.652 because of the higher attenuation.

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 [email protected].
• 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.
