Maximize Your Fibre

Maximize your infrastructure with Wave Division Multiplexing (WDM)

Let's talk about Wave Division Multiplexing (WDM) and how to get more from your fiber...

Generally, fiber connections use 2 fibers – one for transmitting (Tx) and one for receiving (Rx) data:

Both transmit and receive using the same single wavelength e.g. 850, 1310, 1550nm

Typically, if you need to increase bandwidth between sites you have two options:

Installing new optical fiber infrastructure is not only cost-prohibitive but can require months of planning that may impact the ability to turn up new services. Additionally, unlit or “dark” fiber can be scarce and thus expensive.

Upgrading an existing network of switches from say, 10G to 40G is also not without its challenges and requires a significant amount of design effort, planning, and cost.

Maximizing existing optical fiber infrastructure is a challenge faced by network operators large and small. Network operators often face hard choices that balance ROI, timing, and planning for the future; each of which ultimately impacts customer satisfaction.

ProLabs cost-effective Bi-Directional Transceiver and WDM solutions provide operators with solutions to maximize existing fiber infrastructure and avoid the time and expense of installing new optical fiber. ProLabs solutions offer operators opportunities to rapidly provision new services with the assurance of working with a trusted partner.

What are the different types of WDM?

Bi-Directional SFP/SFP+ = Double the bandwidth on existing fibers at relatively low cost


Put simply, WDM is adding multiple signals to the same fiber pair, using different colors of light.

CWDM = Coarse Wavelength Division Multiplexing.

Key applications will be campus networks such as schools and universities and larger businesses with multiple sites.

DWDM = Dense Wavelength Division Multiplexing.

The key application will be MSPs, Mobile Network Operators and Telcos (long haul 40km+ transmission)
