Newport 2×2 WDMs
Newport offers a wide range of single-mode 2×2 WDMs. These devices use fused biconic taper technology and offer low insertion loss, excellent environmental stability and high isolation.
They can be used to separate or combine optical signals at the indicated operating wavelengths. They can also be used as a dichroic coupler to combine signals of different wavelengths (e.g. combining signals in the 980 and 1550 transmission windows).
1. CWDM MUX DEMUX
CWDM MUX DEMUX is a passive optical device that allows multiple optical signals of different wavelengths to pass through the same fiber strand, thus expanding your network bandwidth capacity. It’s also highly stable and reliable. The CWDM Mux Demux Module can be used to combine up to 18 different wavelength signals into a single optical fiber or separate up to 18 optical signals from the same optical fiber to its original form.
Generally, there are two types of CWDM MUX Demux: dual-fiber and single-fiber. In the case where you have only one optical fiber to use, it’s better to choose a single-fiber CWDM Mux Demux. Because it requires only one optical fiber for transmission, it can save your costs and increase your network reliability.
On the other hand, if you want to transmit signals bi-directionally, you should opt for a dual-fiber CWDM Mux Demux. This type of CWDM Mux Demux is designed to transmit signals over the same optical fiber in both directions at the same time, so it is better for long distance transmission applications.
The essential ports on a CWDM Mux DEMUX include the line port, which is used to connect the external fibers to the Mux Demux, and the channel port, which is dedicated to multiplexing and demultiplexing different wavelengths. In addition, some CWDM Mux Demux can be equipped with additional special ports for better network construction. For example, the monitoring port can help you test the power of each individual wavelength and monitor the optical signal-to-noise ratio (OSNR).
2. CWDM MUX
Coarse Wavelength Division Multiplexing (CWDM) is a simple and cost-effective method to increase the capacity of existing fiber infrastructure. 2×2 WDM CWDM devices combine and split wavelengths, reducing the number of optical fiber lines needed for long distance connections.
CWDM devices work over single-mode optical fiber, which has greater travel capacity than multimode fiber and allows signals to reach their destinations more reliably. They are compatible with most standard SFP and SFP+ transceivers, which provide connectivity to CWDM switches, routers, and other networking equipment.
The essential function of a CWDM Mux Demux is to combine different data rates at various wavelengths on the same fiber. Typical ports include line ports used to connect the external fibers to the Mux Demux and channel ports that multiplex and demultiplex different wavelengths.
For example, a CWDM network might utilize 16 wavelengths to support 8 pairs of dual-way transmission. At Site A, an 8-channel CWDM Mux/DEMUX would be installed to use 8 wavelengths for transmitting and 8 for receiving, while at Site B, an identical Mux/DEMUX would be deployed using the opposite pair of wavelengths.
Many engineers choose to add a monitor port to their CWDM Mux Demuxes, which lets them check the incoming and outgoing signal’s dB level. This helps ensure uninterrupted service. Monitor ports are available on both single and dual fiber versions of CWDM Mux Demuxes.

Coarse Wavelength Division Multiplexing (CWDM) technology offers an easy way to increase the capacity of a fiber optic network. It allows you to combine multiple optical signals of different wavelengths into one single line, reducing the number of long fiber lines and thus saving on expensive installation. It also helps you to relieve the existing optical fiber resources, extending their life.
The basic function of CWDM Mux/Demux is to mix data rates of different wavelengths on the same optical fiber to increase network capacity. The essential ports on CWDM Mux/Demux are the line port used to connect the outside fibers and the channel port for multiplexing and demultiplexing wavelengths. This kind of passive MUX/DEMUX supports high bandwidth with low insertion loss, which is suitable for applications such as 1G/10G Ethernet, OTN, SDH/SONET and 8/4/2G Fiber Channel.
In addition to the essential line and channel ports, CWDM Mux Demux often incorporate/customize other special ports for better construction of WDM networks. These extra function ports are not as essential as the line and channel ports, but they will bring some other benefits to your network.
Besides the two essential channels, a CWDM Mux/Demux can include a monitor port which is used for monitoring and managing the signal’s dB level. With the help of this port, network engineers can easily keep data center track of the quality of a signal during transmission and ensure uninterrupted service.
4. CWDM MUX DEMUX
CWDM MUX DEMUX is a passive optical multiplexer/demultiplexer that allows multiple CWDM wavelength channels to pass through a single fiber optic cable. It can bundle and unbundle up to 9 different CWDM wavelengths in a single optical fiber. It has a small footprint and low insertion loss, high channel isolation, wide wavelength range, and low temperature sensitivity. It is suitable for a wide range of applications including 1G and 10G Ethernet, SDH/SONET, Fiber Channel, and CATV.
A CWDM Mux Demux can increase the capacity of an existing optical fiber network without using additional fiber lines. It can also be used to upgrade existing networks to support higher data rates and services. Its ports allow for many types of C/DWDM transceivers to be connected, which makes it a flexible solution for a variety of networking scenarios.
The most important ports on a CWDM Mux Demux are its Line Port and Channel Port. The Line Port is used to connect the outside fibers with the CWDM Mux Demux, while the Channel Port is used to multiplex and demultiplex different wavelengths on the same optical fiber. Channel ports typically use 1310nm or 1550nm wavelengths, which can be transmitted by regular fiber transceivers. This way, it can combine signals from many different sources on a single optical fiber without interference. Moreover, the CWDM Mux DEMUX is available with a Monitor Port which allows you to monitor the power and wavelength of the optical signal in both directions.
