Specialists in CWDM Multiplexers & DWDM Multiplexers

CWDM Multiplexers & DWDM Multiplexers

Pro Optix has been providing CWDM Multiplexers & DWDM Multiplexers since the company’s inception. A technology that was once seen as complex and timely to install is now a simple, robust solution to cost-effectively expand your fiber connectivity and create dedicated channels for specific services or customers. Our experience has led to the launch of the Pro MINI and Pro NANO series, the Pro NANO offering a world-first CS connector-based WDM multiplexer that delivers ultra-high-density never seen before.

Most Telcos, Carriers, City Carriers and large enterprises through to SMB’s have a cost-saving and redundancy-increasing application for WDM multiplexing. As specialists in WDM multiplexing, Pro Optix offer four different series of WDM multiplexers to our customers, depending on performance and density requirements, so please liaise with the Pro Optix team to qualify what meets your needs most effectively.

For an overview of our range of CWDM and DWDM multiplexers please read this page. For exact product specifications, stock and pricing please visit our customer portal >>

Considerations in selecting the correct WDM multiplexer solution


CWDM multiplexing or DWDM multiplexing

CWDM Multiplexers – Coarse Wave Division Multiplexing uses up to 18 wavelengths in a fiber pair and is suitable for shorter distances, max. 120 km.

DWDM Multiplexers – Dense Wavelength Division Multiplexing uses up to 96 wavelengths on one fiber pair and can send more data over longer distances without interference. CWDM and DWDM also use different types of laser plus it is also possible to complete DWDM with light signal amplification for longer distances.

CWDM or DWDM – What is the difference? Read more in our recent blog >

MUX DEMUX Solutions

MUX or DEMUX WDM Multiplexer Solutions

A MUX (multiplexer) multiplies signals into a single/dual fiber using different wavelengths / frequencies of light where each wavelength can send different types of data.

DEMUX (de-multiplexer) separates the signals again at the receiving end.

WDM Multiplexer Density – LC or CS Connectivity

LC connectivity is the traditional and current connectivity for multiplexers. This is a proven solution and is utilized in the Pro Optix Standard, OFM and MINI multiplexer series. LC can be applied in different formats hence density can vary.

CS connectivity is a new type of connectivity for the industry, offering significant density increases alongside upgraded robustness in a new connectivity design patented by Senko.

WDM Density

WDM Multiplexer density, flexibility & scalability

With the arrival of next-generation-high-density and ultra-high-density multiplexers has come the opportunity to save significant rack space – 300% and 600% respectively compared to standard options. To the left is a 9 channel CWDM example.

It is not just about reducing your data centre footprint; it is also about flexibility and scalability. How modular do you need your solution to be? Do you need east, west and north connectivity in 1U? Are you expecting your customer to expand their requirements? If you need flexibility for the future Pro MINI or Pro NANO are the suitable solutions.
