State of the Art
Proximion offers the world's only FBG-based continuous Dispersion Compensation Modules (DCMs). Tens of thousands of units are deployed in networks worldwide, today compensating for dispersion in links that spans more than six laps around the globe.
Best of Both Worlds
Our products are the only ones that combine all the benefits of the FBG and DCF technology. Taking advantage of both full band and channel plan independent compensation.
Ultra Low Loss
The low loss enables a higher degree of freedom when optimizing your system with respect to reach and performance. In longer spans it is a major cost saver reducing the amount of amplification needed with a factor of 3 to 5 compared to DCF.
Perfect Slope Match
Our FBG based DCMs can be designed to perfectly mimic the dispersion slope characteristic of any given fiber type. We guarantee a residual dispersion of less than 2% compared to a value often higher than 10% with DCF. Low residual dispersion is crucial when you decide to migrate to higher bit rates.
With virtually zero latency, our FBG based DCMs can reduce your link latency up to 10 to 20 percent. It is perfectly suited for high-speed networks supporting low latency services.
No matter what your link dispersion looks like there is a solution with our continuous FBG DCMs. So whether you are using G.652 or G.655 fiber, or have a full-band terrestrial or a banded submarine solution you will have the possibility to have zero dispersion over all your channels and even in-between channels. The continuous solution also allows for seamless upgrade to higher bit rate, channel count or even change of channel plan.
Small form factor but full-band dispersion compensation. The FBG design enables an immense space saving resulting in substantial OPEX and CAPEX related savings.
Zero Nonlinear Effects
In a DWDM environment, non-linear effects limit the number of wavelengths per fiber and/or channel spacing. By using FBG DCMs with zero non-linearities you don't add any limitations to your system as is the case using DCF. FBG DCMs have actually proved to even decrease the problem with non-linearities in coherent systems.

The phenomenon that white light can be separated into different colors is named dispersion. Dispersion causes pulses to spread in optical fibers, degrading signals over long distances and ultimately resulting in bit errors.

Design your DCM perfectly tailored to your specific needs. Any dispersion, any bandwidth, any dispersion slope. This unique product offering originates from our ability to manufacture FBGs that are more than 10 times longer than our closest competitor. So do as 9 of the worlds 12 Tier-1 system vendors and provide us your dispersion specification.
Improved Coherent Systems
Continuous DCMs have the potential to improve long haul coherent systems from an economical as well as a technical perspective. Key benefits are: Reduced Power Consumption, Reduced Latency and Reduced Complexity.
Mixed 10G & 100G
When adding 100G coherent channels to legacy 10G networks it is a major risk that the new 100G channels are distorted to the level that signal transmission is impossible. Our technology makes it possible to upgrade any dispersion compensated network to a mixed +100G coherent network. Amongst others AARNet has deployed Proximion's DCMs on 1,600 km network that has Cisco hardware.
How Our FBG
Dispersion compensation utilizing FBGs is based on the introduction of wavelength‐specific time delays through the use of a precisely chirped FBG. Our ultra-long FBGs is inscribed with our versatile and proprietary grating writing technique that gives us unparalleled possibilities.
