Customize Your DCM or FBG

Learn about our customization options below or contact us directly and we will personally help you out. 


Basically our DCMs Come in Four Designs:

Continuous full band – Do as the majority of the Tier-1 system vendors and get perfectly tailored and future proof dispersion solutions with low IL, no latency and no NLE

Continuous banded – If you have a submarine system or another banded solution you can also experience all the benefits of our unique continuous products

Channelized – A low cost alternative with all the benefits of the FBG-design but you have to live with the drawbacks of a non-continuous solution with limited bandwidth

Continuous Slope – Residual slope compensation for submarine and festoon links that often have extreme dispersion slope values



But our DCM variations are endless..

Calculate Link Length, Insertion Loss and Latency

What is your preferred bandwidth?

Any bandwidth and any frequency range is possible

Full C-band or L-band equals ~40 nm


Which fiber is used on your link?

Our solution can be tailored to any fiber type

As an example G.652 (SMF) has a dispersion coefficient of 16.8 ps/nm/km

and G.655 (LEAF) has a dispersion coefficient of 4.2 ps/nm/km


Longer links? The optical performance of our DCMs make them perfect to cascade

A DCM has an IL of 2.5 – 3.8 dB depending on configuration, add as many devices as your link requires


Choose Package

Basically we provide three alternative FBG-packages dependent on grating length

  • Continuous full band products -  Ø 160 x 16 mm
  • Banded solutions (low dispersion)
  • Channelized products – 28 x 15 x 180 mm

Outer packages for continuous solutions are often entirely customized

  • Standard box dimensions 197x212x22.5 mm
  • Standard box of up to four cascaded units in one box are also available
our continuous banded solution - patch cord

Customize Your FBG

Proximion is the leading supplier of advanced FBGs based products with a capability to manufacture straight, chirped or tilted FBGs with a customized group delay profile. Proximion offers continuous FBG lengths of 1 – 10000 mm, >10x longer than any other available FBGs. Our FBGs are currently used in a number of volume applications within the telecom and defense industry and we offer this world leading patented technology for industrial integration in a wide range of applications like fiber lasers, pulse compression, microwave photonics, sensors, metrology, shape sensing, and biotech. Proximion is a reliable partner that uses a flexible writing technique which allows for smaller series but that also easily scales to high volume production due to a highly automated production process.
